Description
Technical Field
The present invention relates to the field of traffic processing, and in particular, to a burst traffic processing method and apparatus for a data center traffic scheduling system.
Background
In order to improve the performance and stability of the flow scheduling system, a polling algorithm is often adopted to decide the distribution of the flow so that the flow is uniformly distributed on a plurality of servers or paths.
Networks using IPv6 traffic are gradually increasing, and a traffic scheduling system adopting IPv4 traffic in the prior art cannot be compatible with scheduling of IPv6 traffic.
In the prior art, when a polling algorithm is adopted to decide the distribution of the traffic, if the polling time is too short when the polling time is set, frequent convergence routing may be caused, so that frequent network oscillation is caused, and bad influence is brought to customer service. However, when the polling time is too long, partial port congestion is caused when the burst traffic is faced, so that traffic scheduling is affected.
Disclosure of Invention
The invention provides a method and a device for processing burst traffic of a data center traffic scheduling system, which are used for solving the problem that partial ports are congested when the current traffic scheduling system faces the burst traffic, so that traffic scheduling is affected.
In a first aspect, the present application provides a method for burst traffic processing in a data center traffic scheduling system, including:
Acquiring flow data of each flow node in real time, and adding an IPv6 header to all data packets transmitted in a first flow node when the flow variation amplitude of the first flow node is larger than or equal to a preset value to acquire an IPv6 data packet;
Determining network planes of all IPv6 data packets corresponding to the first flow node according to the flow property of the first flow node, and determining IPV6 over IPV4 tunnels appointed by all IPv6 data packets according to the network planes;
Carrying out network slicing on each IPv6 data packet to obtain a plurality of data packets to be transmitted, and forwarding each data packet to be transmitted respectively according to an IPV6 over IPV4 tunnel appointed by each IPv6 data packet;
and receiving the transmission data packet of each IPV6 over IPV4 tunnel outlet, merging all the transmission data packets according to the header in the transmission data packet to obtain a merged data packet, and converting the merged data packet into an IPv4 data packet for normal transmission.
Thus, when the burst traffic is faced, the IPv4 data packet is converted into the IPv6 data packet for transmission, so that the transmission of the IPv6 network is supported. And determining the requirements of clients in each flow node according to the flow properties of the flow nodes, and selecting a proper network plane according to different requirements. Furthermore, by performing network slicing on the IPv6 data packet and merging the data packets to be transmitted at the tunnel outlet, the data transmission efficiency can be improved, the problem of port congestion caused by flow change can be solved, and the reliability of flow scheduling can be improved. Meanwhile, the data center network flow is classified, so that the service quality of the data center network can be remarkably improved. The network connection quality of the key service can be ensured.

the data transmission module is used for receiving the transmission data packet of each IPV6 over IPV4 tunnel outlet, combining all the transmission data packets according to the header in the transmission data packet to obtain a combined data packet, and converting the combined data packet into an IPv4 data packet for normal transmission;
Wherein, the data forwarding module includes: a data slicing unit and a tunnel transmission unit;
the data slicing unit is used for carrying out network slicing on each IPv6 data packet to obtain a plurality of data packets to be transmitted, and adding an identification data segment into each data packet to be transmitted;
The tunnel transmission unit is used for setting SRv paths, and sending each data packet to be transmitted to an IPV6over IPV4 tunnel appointed by the corresponding IPv6 data packet through SRv paths according to the identification data segment in each data packet to be transmitted;
the tunnel specifying module includes: a first judging unit and a network plane determining unit;
the first judging unit is used for judging whether the flow property of the first flow node is low-delay flow or not;
The network plane determining unit is configured to determine, when the first judging unit determines that the traffic property of the first traffic node is low-delay traffic, the IPv6 data packets as a traffic plane according to the message headers in all the IPv6 data packets;
the network plane determining unit is further configured to determine, when the first judging unit determines that the traffic property of the first traffic node is not low latency traffic, the IPv6 data packet as a storage traffic plane according to the header of the packet in all the IPv6 data packets.
5. The burst traffic processing apparatus of a data center traffic scheduling system according to claim 4, wherein the header adding module comprises: a preset value determining unit and a data adding unit;
the preset value determining unit is used for determining a preset value according to the flow bearing capacity of each flow node and the polling time in the flow scheduling system;
The data adding unit is configured to transmit all data packets transmitted in a first traffic node to a SRv server when a traffic variation amplitude of the first traffic node is greater than or equal to a preset value, and obtain an IPv6 data packet after adding an IPv6 header to the data packet by the SRv server.
6. The burst traffic processing device of the data center traffic scheduling system according to claim 4, further comprising a real-time monitoring module;
the real-time monitoring module is used for acquiring flow data of each flow node in real time, stopping adding an IPv6 header to a data packet transmitted in a first flow node when the flow variation amplitude of the first flow node is smaller than a preset value, and normally transmitting the data packet by an IPv4 protocol.
