The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for modifying an MSS.

Step S104: Modify the first MSS value to a second MSS value, where the second MSS value refers to an MSS value obtained by the data device according to the network where the data device is located.

Through the foregoing steps, the first MSS value in the network connection performed by the data device is uniformly modified into the second MSS value saved in the data device, and the foregoing technical solution is used to solve the related technology, because the operator has the MSS value Different definitions, the server often needs to shard the data packet when sending the data packet, which is easy to cause the server to send the data packet with low transmission rate and poor user experience, and thus can pass the number The second MSS value in the network connection performed by the device is consistent with the first MSS value stored in the data device to ensure the data transmission rate of the server, which brings a good user experience to the user.

In other words, the above technical solution of the embodiment of the present invention intelligently adjusts the MSS value to ensure that the rate is up to standard, and ensures that the MTU value does not change, thereby preventing such a situation that seriously affects the user experience that cannot be used by some applications.

Optionally, determining the second MSS value by: obtaining some or all network nodes in the network where the data device is located; transmitting a transmission control protocol TCP connection to some or all network nodes, and receiving a TCP handshake fed back by some or all network nodes Data packet; parsing all MSS values corresponding to some or all network nodes from the TCP handshake data packet, and selecting the smallest one from all MSS values as the first MSS value, that is, taking some or all network nodes between the terminal and the server as objects, All MSS values corresponding to some or all network nodes are parsed, and the smallest one is selected as the first MSS value from all MSS values.

The abbreviation of the WiFi, which may be a ufi device, or other data device having a WiFi function, is not limited in this embodiment of the present invention.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A better implementation. Based on such understanding, the technical solution of the present invention, which is essential or contributes to the prior art, may be embodied in the form of a software product stored in a storage medium (eg, ROM/RAM, disk, and optical disk include instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the methods of various embodiments of the present invention.

In the embodiment, a modification device of the MSS is further provided, and the device is used to implement the foregoing embodiments and preferred embodiments, and details are not described herein. As used below, the term "module" may implement a combination of software and/or hardware of a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware, is also possible and contemplated.

2 is a structural block diagram of a modification apparatus of an MSS according to an embodiment of the present invention. As shown in FIG. 2, the apparatus includes:

The first obtaining module 20 is configured to acquire a first MSS value received by the data device with the WiFi function for performing a network connection;

The modifying module 22 is configured to modify the first MSS value to a second MSS value, where the second MSS value refers to an MSS value obtained by the data device according to the network where the data device is located.

The first MSS value in the network connection performed by the data device is uniformly modified into the second MSS value saved in the data device by using the foregoing various functions of the modules, and the foregoing technical solution is adopted to solve the related technology, because the operator The MSS value is defined differently, so the server often needs to perform operations such as fragmentation of the data packet when sending the data packet, which may easily lead to the problem that the server transmits the data packet with low transmission rate and poor user experience, and thus can pass the data packet. The second MSS value in the network connection performed by the data device is consistent with the first MSS value stored in the data device to ensure the data transmission rate of the server, which brings a good user experience to the user.

FIG. 3 is another structural block diagram of a device for modifying an MSS according to an embodiment of the present invention. As shown in FIG. 3, the device further includes: a second acquiring module 24 configured to be part or all of the network nodes in the network where the data device is located; The sending module 26 is configured to send a transmission control protocol TCP connection to some or all of the network nodes; and the receiving module 28 is configured to receive some or all of the network nodes. The TCP handshake packet is fed; the parsing module 30 is configured to parse all MSS values corresponding to some or all network nodes from the TCP handshake packet, and select the smallest MSS value from all MSS values as the second MSS value.

In the embodiment of the present invention, a system for modifying an MSS is further provided, including:

a data device having a wireless fidelity WiFi function, wherein the data device is configured to acquire a first MSS value received by the data device having the WiFi function for performing a network connection; and modify the first MSS value to the second The MSS value, where the second MSS value refers to the MSS value obtained by the data device according to the network where the data device is located.

With the modification system of the MSS provided by the present invention, the first MSS value in the network connection performed by the data device is uniformly modified into the second MSS value saved in the data device, and the foregoing technical solution is used to solve the related art. Since the operator defines the MSS value differently, the server often needs to perform the operation of fragmenting the data packet when sending the data packet, which may cause the transmission rate of the server to transmit the data packet and the user experience to be poor. The second MSS value in the network connection to be performed by the data device and the first MSS value stored in the data device can be consistent to ensure the data transmission rate of the server, which brings a good user experience to the user.

Optionally, the foregoing data device is further configured to acquire some or all network nodes in the network where the data device is located; send a transmission control protocol TCP connection to some or all network nodes, and receive a TCP handshake packet fed back by some or all network nodes. And parsing the MSS value corresponding to some or all network nodes from the TCP handshake data packet, and selecting the smallest MSS value from the MSS value as the second MSS value.

The above technical solutions are explained below in conjunction with an example, but are not intended to limit the embodiments of the present invention.

The example of the present invention can be used to adjust the MSS value to adapt to the operator's network, if the user terminal does not modify the MTU by using the intermediate device (ie, the data device with the wireless fidelity WiFi function). This can achieve higher performance when downloading data, and bring a good experience to the user, while not modifying the MTU value to prevent failure problems that cannot be segmented.

The technical solution of the exemplary embodiment of the present invention can also be considered from the following points:

4 is a structural block diagram of a modified system of an MSS according to an example of the present invention. As shown in FIG. 4, the method mainly includes:

The network status module 40 is detected, the network node module 42 is acquired, the intelligent analysis module 44 is set, and the installation module 46 is set. After detecting the network connection success, the network status module 40 first sends a series of ping packet data on the board side, and records an address that can be normally communicated. Then, the acquiring network node module 42 obtains the IP address on each node by using the address obtained in the previous step, and then through route tracking, and saves and records these addresses. The intelligent parsing module 44 will parse the TCP handshake data returned by the node according to all the IP addresses obtained in the previous step, and intercept the TCP handshake data packet returned by the node, and then parse the MSS value, and finally select the smallest MSS. value. The setup installation module 46 sets the optimal MSS value to the above data device, whereby all the data devices will automatically modify the MSS value to maintain the same network value as the operator, and when downloading data, the data rate will be lower than The rate at which any modification is made is greatly improved, and the MTU value is not modified, so that the performance and evaluation of the device by the user will be very high.

FIG. 5 is a flowchart of a method for modifying an MSS according to an example of the present invention. The following detailed flowchart is used to explain how the above modules can intelligently adjust the MSS value.

Step S502: The terminal device is normally connected to the network. After the network is successfully connected, the network status module 40 is invoked. The module uses a ping, domain name server (DNS) analysis to determine whether the network can access the internet network normally. And select a well-known IP address, the following 8.8.8.8 address as an example. When the network is not normal, the detection network status module 40 is continuously called until the network is normal.

Step S504, after the network status is normal, call the acquisition network node module 42, and then use the traceroute tool to obtain some or all network nodes between the terminal and the server 8.8.8.8, some of which may be in the carrier network, some It may not be in the carrier network. Since it is impossible to distinguish whether it belongs to the carrier network node, all network nodes are recorded.

Step S506, after successfully acquiring the network node, calling the intelligent parsing module 44, the module will perform a TCP connection with the recorded network node by constructing a socket, and intercept the returned TCP handshake data packet by using the hook function, and the slave data packet. Obtain the MSS value returned by each network node, compare all MSS values, and select the smallest MSS value.

Step S508, after the intelligent parsing module 44 is completed, the setting installation module 46 is invoked, and a rule is constructed in the data device by using the iptables tool, for example, the following rules are

Iptables-t mangle-I POSTROUTING-p tcp--tcp-flags SYN,RST SYN-j TCPMSS--set-mss$min_mss

This rule will modify the mss value of min_mss for all tcp handshake connections over the data device to ensure that the device can better adapt to the carrier's network.

It should be noted that each of the above modules may be implemented by software or hardware. For the latter, the foregoing may be implemented by, but not limited to, the foregoing modules are all located in the same processor; or, the above modules are in any combination. The forms are located in different processors.

The present invention also provides a method for setting the smart identification mss value. Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method provided by the method, which mainly includes four modules and is disposed in a wireless router. The provided process ultimately installs the optimal MSS value into the wireless routing module.

Since the MTU values in many carrier networks are different, the MSS values are different. Modifying the MTU value directly has some problems that affect the user experience. Therefore, modifying the MSS value can ensure a better user experience. At the same time, the MSS value can be modified. In the above-mentioned data device (which may include a ufi device or a MiFi device), the network can be intelligently adjusted to ensure that the network can be adjusted under each operator's network. The equipment can achieve a good rate effect, which brings users a high quality experience and improves the competitiveness of the product.

In summary, the embodiment of the present invention achieves the following technical effects: in the related art, since the operator defines the MSS value differently, the server often needs to perform the operation of fragmenting the data packet when sending the data packet. In this way, the problem that the transmission rate of the data packet sent by the server is low and the user experience is poor, and the second MSS value in the network connection to be performed by the data device can be consistent with the first MSS value stored in the data device. Guarantee the data transmission rate of the server, bringing a good user experience to the user.
