FIG. 3 is a flowchart of a method for transmitting service data according to an embodiment of the present invention. Referring to Figure 3, the method includes:

Step 301: In the process of transmitting, by the transport layer, the service data of the first service by using the first transmission protocol and the first transmission parameter, the transport service layer receives the transport status information, where the transport status information includes at least transport layer status information, and the first transport protocol And the first transmission parameter is a transmission protocol and transmission parameter currently configured for the transport layer.

When the terminal uses the services of video communication, video on demand, web browsing, etc., in order to obtain the data required by the service, the terminal needs to transmit the service data through the network, and the service layer is subjected to the transmission layer during the transmission process. The impact of state changes, for example, when transmission congestion occurs in the transport layer, it will cause problems such as packet loss and packet transmission delay. Therefore, in the process of service data transmission, in order to target different transmission state information, the transmission protocol is timely. And the transmission parameters are adjusted, and the transmission service layer of the terminal needs to receive the transmission status information of the information in the transmission process.

In addition, in the process of service data transmission, not only the transmission status of the transport layer will affect the service data transmission, but also the network status of the network layer will also affect the service data transmission. For example, when network congestion occurs at the network layer, It also causes problems such as packet loss and packet transmission delay. Therefore, the transmission status information may include not only transport layer status information but also network layer status information.

Further, before the transmission service layer receives the transmission status information, the transmission service layer may report the current transmission status information to the transmission service layer by using the following methods (1)-(3), as follows: Said.

(1) The transmission service layer receives a service requirement parameter sent by the application layer, where the service requirement parameter is a parameter required when the first service provided by the application layer is in a normal state, and obtains a threshold parameter from the service requirement parameter. And the key event is used to report the transmission status information to the transport service layer when the transmission parameter of the correlation layer exceeds the threshold parameter, and the related layer includes at least the transport layer.

The service requirement parameter includes a minimum threshold parameter that can be tolerated when the first service is in a normal state. In the service data transmission process, if the transmission parameter used for transmitting information exceeds the minimum threshold parameter, the terminal performs the A variety of problems occur in the process of a service, and the first service cannot be performed normally. Therefore, in order to ensure the normal use of the first service, after the transmission service layer receives the service requirement parameter sent by the application layer, Obtaining a threshold parameter from the service requirement parameter, and based on the threshold parameter, the transport service layer registers a key event with the relevant layer. After the key event is successfully registered, when the transmission parameter used for the service data transmission exceeds the threshold parameter, the relevant layer The current transmission status information is reported to the transport service layer.

The service requirement parameter may include multiple parameters. When the transport service layer obtains the threshold parameter from the service requirement parameter, the transport service layer may determine the service identifier of the first service currently provided by the application layer, and is based on The service identifier of the service currently provided by the application layer is obtained from the corresponding relationship between the stored service identifier and the parameter identifier, and the corresponding parameter identifier is obtained, and the obtained parameter identifier is obtained from multiple parameters included in the service requirement parameter. Corresponding parameters, and the obtained parameters are determined as threshold parameters.

In the process of the service data transmission, some request messages are transmitted between the application layer and the transport service layer, and the request message may carry the service identifier of the first service currently provided by the application layer. Therefore, the transport service layer may The request message obtains the service identifier of the service currently provided by the application layer. For example, the request message may be a connection establishment message, which is not specifically limited in the embodiment of the present invention.

It should be noted that the service identifier is used to uniquely identify the first service that is currently provided by the application layer, and the service identifier may be a service name, a service number, and the like of the first service currently provided by the application layer. This example does not specifically limit this.

It should be noted that the parameter identifier is used to uniquely identify the parameter, and the parameter identifier may be a name of the parameter, a symbol of the parameter, an abbreviation of the parameter, and the like, for example, a transmission delay included in the service requirement parameter. The identifier may be RTT, the identifier of the packet loss rate may be ρ, the identifier of the congestion window may be CWND, and the identifier of the network bandwidth may be BW, etc., which is not specifically limited in this embodiment of the present invention.

For example, the service identifier of the service currently provided by the application layer is ID1, and the transport service layer is based on the service identifier ID1, and the corresponding parameter identifier is obtained as RTT from the correspondence between the service identifier and the parameter identifier shown in Table 1 below. ρ, the transport service layer identifies the RTT and ρ based on the parameter, and obtains the transmission delay from the service requirement parameter, the parameter corresponding to the RTT is 50 ms, the parameter corresponding to the packet loss rate ρ is 0.04%, and the transmission service layer transmits the delay time RTT 50 ms and The packet loss rate ρ0.04% is determined as the threshold parameter.

Table 1

It should be noted that, in the embodiment of the present invention, only the correspondence between the service identifier and the parameter identifier shown in the foregoing Table 1 is taken as an example. The foregoing Table 1 does not limit the embodiment of the present invention.

For example, the service is a video on demand service, and the service requirement parameters sent by the transmission service layer to receive the application layer include a transmission delay, a packet loss rate, a congestion window at the transmitting end, a maximum transmission unit, a throughput rate, and the like, and the transmission service layer needs the service layer. In the parameter, the obtained threshold parameters are transmission delay and packet loss rate, and the transmission delay is 50 ms, and the packet loss rate is 0.04%. Based on the transmission delay of 500 ms and the packet loss rate of 0.04%, the transmission service layer registers with the relevant layer. After the critical event is successfully registered, if the current transmission delay of the relevant layer in the service data transmission process is 60ms, the current transmission delay is 60ms greater than the transmission delay in the threshold parameter by 50ms, so that the relevant layer will transmit the current transmission state. The information is reported to the transport service layer.

(2) The transport service layer sends the reporting period to the relevant layer, so that the related layer reports the transmission status information to the transport service layer every other reporting period.

In order to ensure that the service is in a normal state, that is, to ensure that the service data transmission of the transport layer is performed normally, the transport service layer can also periodically acquire the transport status information of the relevant layer, so that the service data transmission of the transport layer can be performed in real time. Ground monitoring will not impose an excessive burden on the relevant layers. Therefore, the transport service layer may send the reporting period to the relevant layer, so that the relevant layer reports the transmission status information to the transport service layer every other reporting period.

It should be noted that the reporting period may be set in advance, for example, the reporting period is 5 min, 10 min, 30 min, and the like, which is not specifically limited in this embodiment of the present invention.

For example, the reporting period is 10 minutes, and the transport service layer sends the reporting period to the relevant layer for 10 minutes, so that the relevant layer sends the transmission status information to the transport service layer every 10 minutes.

(3) when the first transmission connection of the related layer transmission service data is disconnected, reporting the transmission to the transmission service layer Enter status information.

Before the service data transmission, the transport service layer needs to establish a first transmission connection between the relevant layer and the server, and perform service data transmission through the first transmission connection, and the first transmission connection of the relevant layer for performing service data transmission. When disconnected, the application layer cannot obtain the data required by the currently provided service, thereby affecting the normal operation of the service. Therefore, when the first transmission connection of the relevant layer for performing service data transmission is disconnected, the relevant layer may transmit to the relevant layer. The service layer reports the transmission status information.

It should be noted that, in the embodiment of the present invention, since the related layer includes at least the transport layer, of course, in order to further improve the efficiency of the service data transmission, the related layer may further include a network layer. Therefore, the transport service layer can pass not only the foregoing three types. The method can obtain the status information of the transport layer. Of course, the transport service layer can also obtain the transport layer status information and the network layer status information by using the foregoing three methods, that is, the transport service layer can obtain at least the transport layer status information. This is not specifically limited.

Step 302: Obtain a transmission delay and a packet loss rate from the transmission state information, and determine a transmission state of the correlation layer based on the transmission delay and a packet loss rate.

When the transmission service layer receives the transmission status information, in order to determine the transmission status of the current service data transmission, and timely adjust the service data transmission process based on the transmission status, to ensure normal operation of the service data transmission, therefore, The transmission service layer may obtain a transmission delay and a packet loss rate from the transmission status information, and determine a transmission status of the correlation layer based on the transmission delay and the packet loss rate.

The operation of the transmission layer is determined by the transmission service layer based on the transmission delay and the packet loss rate. The operation may be: when the transmission delay is greater than or equal to the first specified delay and the packet loss rate is greater than or equal to the first designation. When the packet loss rate is determined, the transmission state of the relevant layer is determined to be an overload state. When the transmission delay is less than or equal to the second specified delay and the packet loss rate is less than or equal to the second specified packet loss rate, the transmission state of the relevant layer is determined to be light. If the transmission delay is less than the first specified delay and greater than the second specified delay, or the packet loss rate is less than the first specified packet loss rate and greater than the second specified packet loss rate, the transmission state of the relevant layer is determined to be normal. status.

It should be noted that the first specified delay, the second specified delay, the first designated packet loss rate, and the second specified packet loss rate may be set in advance, and the first specified delay is greater than the second specified delay, and the first The specified packet loss rate is greater than the second specified packet loss rate. For example, the first specified delay is 50ms, 55ms, and the second specified delay is 10ms, 20ms, etc., and the first specified packet loss rate is 0.04%, 0.05%, etc. The second specified packet loss rate is 0.01%, etc., which is not specifically limited in the embodiment of the present invention.

For example, the first specified delay is 50 ms, the second specified delay is 10 ms, the first specified packet loss rate is 0.04%, and the second specified packet loss rate is 0.01%, and the transport service layer obtains the transmission status information. The transmission delay is 60 ms and the packet loss rate is 0.06%. Since the transmission delay is 60 ms larger than the first specified delay of 50 ms, and the packet loss rate is 0.06%. The first specified packet loss rate is 0.04%. Therefore, the transport service layer determines that the transmission state of the relevant layer is an overload state.

It should be noted that, since the transport service layer can obtain at least the transport layer state information, when the transport state information includes the transport layer state information, the transport service layer can obtain the transport layer transmission delay and loss from the transport layer state information. Packet rate, and based on the transmission delay and packet loss rate of the transport layer, determine the transmission state of the transport layer, and when the transport state information includes not only transport layer state information but also network layer state information, the transport service layer can not only transmit In the layer state information, the transmission delay and the packet loss rate of the transport layer are obtained, and the transmission state of the transport layer is determined based on the transmission delay and the packet loss rate of the transport layer, and the network layer is also obtained from the network layer state information. The transmission delay and packet loss rate, and based on the transmission delay and packet loss rate of the network layer, determine the transmission state of the network layer.

Step 303: Determine the service type to which the first service belongs and the network type of the network currently connected to the network layer.

In order to make the service data transmission process more accurate and more targeted, to ensure the smooth progress of the service data transmission, improve the speed and quality of the service data transmission, and make the first service provided by the application layer in a normal state, The transport service layer needs to determine the type of service to which the first service belongs and the type of network to which the network layer is currently connected.

The operation of the service layer to determine the service type to which the first service belongs may be: the service layer obtains the service identifier of the first service, and based on the service identifier, the correspondence between the stored service identifier and the service type. And obtaining the corresponding service type, and determining the obtained service type as the service type to which the service currently provided by the application layer belongs.

For example, the transport service layer obtains the service identifier of the first service as the ID1, and the transport service layer obtains the corresponding service type as the type from the correspondence between the service identifier and the service type shown in the following Table 2 based on the service identifier ID1. 1, and determine the type 1 as the type of service to which the first service belongs.

Table 2

It should be noted that, in the embodiment of the present invention, only the correspondence between the service identifier and the service type shown in the foregoing Table 2 is taken as an example. The foregoing Table 2 does not limit the embodiment of the present invention.

Wherein, when the transport service layer determines the network type of the network currently connected to the network layer, the transport service layer can directly determine the network type of the network currently connected to the network layer based on the network currently connected by the terminal, and Obtaining a plurality of consecutive transmission delays and packet loss rates from the plurality of consecutively received transmission state information, and determining a network type of the network currently connected to the network layer based on the plurality of consecutive transmission delays and packet loss rates.

The operation layer of the transmission service layer determines the network type of the network currently connected to the network layer based on the multiple consecutive transmission delays and packet loss rates. The transmission service layer obtains the transmission time from the multiple consecutive transmission delays. Determining the maximum value and the minimum value of the transmission delay, and determining the amount of delay variation of the plurality of consecutive transmission delays based on the maximum value of the transmission delay and the minimum value of the transmission delay, and from the plurality of consecutive packet loss rates, Obtaining a maximum value of the packet loss rate and a minimum packet loss rate, and determining a packet loss rate change of the multiple consecutive packet loss rates based on the maximum packet loss rate and the minimum packet loss rate, when the multiple consecutive transmission delays If the first threshold is greater than the first threshold, the delay variation is less than the second threshold, and the packet loss rate is less than the third threshold, determine that the network type of the network currently connected to the network layer is a wireless network; otherwise, determine the current network layer. The network type of the connected network is a non-wireless network, that is, when the obtained multiple consecutive transmission delays are always large and occasional packet loss occurs, the transport service layer can determine the network connected network currently. The network type for the wireless network, otherwise, determining that the current network layer network of the type of network connected to a non-wireless network.

It should be noted that the first threshold, the second threshold, and the third threshold may be set in advance, for example, the first threshold is 30 ms, 35 ms, the second threshold is 5 ms, 7 ms, and the third threshold is 0.015%, 0.002%, and the like. This embodiment of the present invention does not specifically limit this.

In addition, the transport service layer can determine the network type of the network currently connected to the network layer based on the multiple consecutive transmission delays and packet loss ratios. Of course, in practical applications, the transport service layer can also be based on the multiple consecutive The transmission delay and the packet loss rate, as well as other consecutive parameters, determine the network type of the network currently connected to the network layer, which is not specifically limited in this embodiment of the present invention.

Step 304: Determine a second transmission protocol and a second transmission parameter based on the transmission delay, the packet loss rate, the transmission status, the service type, and the network type.

The transmission service layer needs to be based on the transmission delay, packet loss rate, and transmission, in order to ensure that the first service provided by the application layer can be in a normal state and avoid transmission congestion and data packet loss during service data transmission. The status, the type of service, and the type of network determine the second transmission and the second transmission protocol parameters. And determining, according to the transmission delay, the packet loss rate, the transmission status, the service type, and the network type, the operations of determining the second transmission and the second transmission protocol parameters: determining the second transmission based on the service type and the network type. The protocol determines the second transmission parameter based on the transmission delay, the packet loss rate, and the transmission status.

When the transport service layer determines the second transport protocol based on the service type and the network type, the transport service layer may be based on the service type and the network type, and the correspondence between the stored service type, the network type, and the transport protocol. In the relationship, the corresponding transport protocol is obtained, and the obtained transport protocol is determined as the second transport protocol.

For example, the network type is a wireless network, and the transport service layer can be based on the service type as type 1 and the wireless network. In the corresponding relationship between the service type, the network type, and the transport protocol shown in Table 3 below, the corresponding transport protocol is obtained as protocol 1, and the transport service layer determines the protocol 1 as the second transport protocol.

table 3

It should be noted that, in the embodiment of the present invention, only the correspondence between the service type, the network type, and the transmission protocol shown in the foregoing Table 3 is taken as an example. The foregoing Table 3 does not limit the embodiment of the present invention.

When the transmission service layer determines the second transmission parameter based on the transmission delay, the packet loss rate, and the transmission state, if the transmission state is a normal state, the transmission service layer determines that the service data transmission is in a normal state, and can fully utilize the The resources provided by the network layer and the transport layer do not cause congestion or packet loss, so that the transport service layer can directly determine the first transmission parameter as the second transmission parameter; if the transmission state is abnormal, That is, when the transmission state is an overload state or a light load state, the transmission parameters configured for the transport layer are different for different transmission protocols, and the transmission protocol can be classified into reliable according to the reliability of the service data transmission. Transmission protocols and unreliable transmission protocols. For example, the TCP protocol is a typical reliability transmission protocol, and the UDP protocol is a typical unreliable transmission protocol. Therefore, for whether the second transmission protocol is a reliable transmission protocol, and the transmission service layer determines the second transmission parameter based on the transmission delay and the packet loss rate, the two transmission parameters may include two cases, as described below.

In the first case, when the second transmission protocol is an unreliable transmission protocol, the transmission service layer determines, according to the transmission delay and the packet loss rate, the delay range to which the transmission delay belongs and the packet loss to which the packet loss rate belongs. Rate range, and based on the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs, obtain the corresponding correspondence from the correspondence between the stored delay range, the packet loss rate range, and the transmission parameter. The parameters are transmitted and the obtained transmission parameters are determined as the second transmission parameters.

The operation of the transmission service layer to determine the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs may be: the delay interval of the transmission service layer to obtain the storage, based on the transmission delay and the packet loss ratio. And the corresponding relationship between the packet loss rate range and the transmission parameter includes a delay range and a packet loss rate range, and multiple delay ranges and multiple packet loss rate ranges are obtained, for each of the multiple delay ranges. The extension range, when the transmission delay is greater than the minimum value of the delay range and less than the maximum value of the delay range, the transmission service layer determines the delay range as the delay range to which the transmission delay belongs; for the same reason, For each of the multiple packet loss rate ranges, when the packet loss rate is greater than the packet loss rate When the minimum value of the rate range is less than the maximum value of the packet loss rate range, the transport service layer determines the packet loss rate range as the packet loss rate range to which the packet loss rate belongs.

Further, when the transmission state is an overload state, the transport service layer determines that congestion occurs in the service data transmission, and the phenomenon of packet loss is accompanied by adjusting the first transmission parameter to alleviate congestion and packet loss of the transport layer. The phenomenon ensures that the service currently provided by the application layer can be in a normal state; if the transmission state is a light load state, the transport service layer determines that there are fewer data packets transmitted during the service data transmission process, and fails to fully utilize the network layer and transmission. The resources provided by the layer can adjust the first transmission parameter to enable the service currently provided by the application layer to be in a better state to improve the service quality of the service.

For example, the transmission state is an overload state, the transmission delay is 60 ms, and the packet loss rate is 0.06%. The transmission service layer determines that the service layer transmission process of the transmission layer is congested, and is accompanied by a packet loss phenomenon, in order to slow down. The loss of the data packet ensures that the service currently provided by the application layer can be in a normal state. The transmission service layer determines the delay range of the transmission delay of 60 ms based on the transmission delay of 60 ms and the packet loss rate of 0.06% (50, 65). The packet loss rate of the packet loss rate of 0.06% belongs to (0.04%, 0.08%), so that the transport service layer is based on the delay range (50, 65) and the packet loss rate range (0.04%, 0.08%). From the correspondence between the delay range, the packet loss rate range and the transmission parameter shown in Table 4 below, the corresponding transmission parameter is obtained as parameter 2, and the parameter 2 is determined as the second transmission parameter.

Table 4

It should be noted that, in the embodiment of the present invention, only the correspondence between the delay range, the packet loss rate range, and the transmission parameter shown in Table 4 is taken as an example. The foregoing Table 4 does not apply to the embodiment of the present invention. The composition is limited.

In the second case, when the second transmission protocol is a reliability transmission protocol, the transmission service layer determines the delay range to which the transmission delay belongs and the packet loss rate to which the packet loss rate belongs based on the transmission delay and the packet loss ratio. Range, and based on the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs, obtain corresponding congestion from the correspondence between the stored delay range, the packet loss rate range, and the congestion algorithm. The algorithm, the transport service layer determines the second transmission parameter based on the congestion algorithm.

The transmission service layer determines, according to the transmission delay and the packet loss rate, a delay range to which the transmission delay belongs and the The packet loss rate range of the packet loss rate is similar to that of the first case described above, and details are not described herein again.

In addition, when the transport service layer determines the second transmission parameter based on the congestion algorithm, the transport service layer may be based on the congestion algorithm, from the stored congestion algorithm and the adjustment ratio, due to different congestion algorithms, corresponding to different adjustment ratios. In the correspondence, the corresponding adjustment ratio is obtained, and the adjustment ratio is multiplied by the first transmission parameter to obtain a second transmission parameter.

For example, the second transmission protocol is a reliability transmission protocol, and the transmission service layer determines the delay range of the transmission delay of 60 ms based on the transmission delay of 60 ms and the packet loss rate of 0.06%, and the packet loss rate is (50, 65). The packet loss rate of 0.06% belongs to (0.04%, 0.08%), so the transmission service layer is based on the delay range (50, 65) and the packet loss rate range (0.04%, 0.08%), as shown in Table 5 below. In the corresponding relationship between the delay range, the packet loss rate range and the congestion algorithm, the corresponding congestion algorithm is obtained as algorithm 2, and the transmission service layer is based on the algorithm 2, from the congestion algorithm and the adjustment ratio shown in Table 6 below. In the corresponding relationship, the corresponding adjustment ratio is obtained as the ratio 2, and based on the ratio 2, each parameter included in the first transmission parameter is multiplied by the ratio 2 to be adjusted to obtain the second transmission parameter.

table 5

It should be noted that, in the embodiment of the present invention, only the correspondence between the delay range, the packet loss rate range, and the congestion algorithm shown in Table 5 is taken as an example. The foregoing Table 5 does not apply to the embodiment of the present invention. The composition is limited.

Table 6

Congestion algorithm Adjustment ratio Algorithm 1 Ratio 1 Algorithm 2 Ratio 2 Algorithm 3 Ratio 3 ...... ......

It should be noted that, in the embodiment of the present invention, only the correspondence relationship between the congestion algorithm and the adjustment ratio shown in Table 6 above is taken as an example, and the above-mentioned Table 6 does not limit the embodiment of the present invention.

Further, the transmission status information may include not only the transport layer status information but also the network layer status information. Therefore, the transport service layer may obtain the second transmission and the second not only through the transport layer status information but also through the foregoing steps 302-304. When transmitting the protocol parameters, the second transmission protocol and the second transmission protocol parameters may be comprehensively determined based on the transport layer state information and the network layer state information, so that the adjusted second transmission protocol and the second transmission parameter may be further Accurate to ensure the smooth transmission of business data transmission at the transport layer, improve the speed and quality of business data transmission.

That is, in the embodiment of the present invention, the transport service layer determines the second transport protocol and the second transport protocol parameters to include two methods: the first method, the transport service layer determines the second transport protocol based on the transport layer state information. The second transmission protocol parameter; the second method, the transmission service layer determines the second transmission protocol and the second transmission protocol parameter based on the transport layer state information and the network layer state information.

Step 305: Send the second transmission protocol and the second transmission parameter to the transport layer, so that the transport layer transmits subsequent service data of the first service based on the second transmission protocol and the second transmission parameter.

When the transport service layer determines the second transport protocol and the second transmission parameter, the transport service layer sends the second transport protocol and the second transmission parameter to the transport layer, so that the transport layer performs the second transport protocol and the second transmission parameter. Service data transmission to control the data transmission process of the service, avoid congestion and packet loss at the transport layer or network layer, and enable service data transmission to fully utilize the resources of the transport layer and the network layer to improve service data transmission. Speed and quality, while ensuring that the services currently provided by the application layer are in a normal state.

Further, after the transport service layer sends the second transport protocol and the second transmission parameter to the transport layer, so that the transport layer performs service data transmission based on the second transport protocol and the second transmission parameter, in order to make the next service data The transmission can enter the normal state more quickly to reduce the time of adjusting the transmission protocol and transmission parameters of the transmission layer, and the transmission service layer can store the second transmission protocol and the second transmission parameter, when the transmission layer re-establishes the second transmission of the service data. When transmitting the connection, the transport service layer can directly configure the transport protocol and transmission parameters of the transport layer as the second transport protocol and the second transmission parameter.

For example, the second transmission protocol is a TCP protocol, and the second transmission parameter includes parameters such as a congestion window, a maximum transmission unit, a buffer, and a transmission bandwidth, and the congestion window is 20 kb/s, the maximum transmission unit is 110 bits, the buffer is 3 M, and the transmission is transmitted. The bandwidth is 5 M/s, etc., and the transport service layer stores the congestion window 20 kb/s, the maximum transmission unit 110 bit, the buffer 3M, the transmission bandwidth 5 M/s, etc. included in the second transmission protocol TCP protocol and the second transmission parameter, when the When the transport layer re-establishes the second transport connection for transmitting service data, the transport service layer can directly configure the transport protocol of the transport layer as the TCP protocol, configure the congestion window included in the transmission parameter to be 20 kb/s, and configure the maximum transmission unit to be 110 bits. The buffer configuration is 3M, and the transmission bandwidth is configured to 5M/s, so that the service data transmission can enter the normal state more quickly.

In the embodiment of the present invention, when the transport layer transmits the service data of the first service by using the first transmission protocol and the first transmission parameter, the transport service layer receives the transport status information, where the transport status information includes at least the transport layer status information, and the transmission The service layer determines the second transmission protocol and the second transmission parameter based on the transmission status information, and sends the second transmission protocol and the second transmission parameter to the transport layer, so that the transport layer transmits the first according to the second transmission protocol and the second transmission parameter. The service data of the service can be used to transmit the service data of the first service by using a more efficient second transmission protocol, thereby avoiding congestion and packet loss during the transmission of the service data, and improving the speed and quality of the service data transmission. .
