A distributed splitter based on SDN architecture and its creation method

Abstract

The invention discloses a distributed splitter based on SDN architecture and its creation method. The whole splitter includes an access layer for collecting mirrored traffic in different areas, and a core for summarizing received data streams in different areas. The access layer and the core layer, and the core layer and the delivery layer are interconnected in pairs. And add filtering strategy, delivery strategy and network processing node on the infrastructure of the access layer, core layer and delivery layer. The splitter of the present invention is a traffic collection and distribution platform with simple configuration, strong expansibility, and very accurate flow, which meets the ever-increasing demand for more efficient and refined management of traffic.

Description

technical field [0001] The invention relates to a distributed splitter based on an SDN architecture and a creation method thereof, belonging to the technical field of network communication. Background technique [0002] At the egress of the campus network or campus network, some bypass traffic analysis devices are generally deployed. At present, the commonly used method is to transmit the network mirrored traffic to the bypass device by means of mirroring port traffic, network TAP (tap) and optical splitter. However, as more and more bypass devices are deployed, this method encounters more and more problems, such as: [0003] 1. Lack of unified planning: various monitoring devices are deployed and monitored independently; [0004] 2. Limited resources: The traditional method of port mirroring and optical splitter is complicated to operate, and port mirroring occupies limited ports of the core device. If the optical path attenuation is too high, it will not only cause the n...

AI Technical Summary

Problems solved by technology

[0003] 1. Lack of unified planning: various monitoring devices are deployed and monitored independently;

[0004] 2. Limited resources: The operation of port mirroring and optical splitter in the traditional method is complicated, and port mirroring occupies limited ports of the core equipment. If the optical path attenuation is too high, it will not only cause the network port of the bypass device to go down, but also affect the stability of the inline link. ;

[0005] 3. Cloud incompetence: Traditional methods cannot cover virtual network architecture, collect cloud data, etc.;

[0006] 4. Limited expansion: Traditional methods can only provide limited filtering functions, which have low scalability and difficult management

This has great restrictions on the development of business and the expansion of network scale.

For example, the replacement of core equipment (with a large number of interfaces) will increase operating costs, require rewiring, and cause business interruption and other problems; moreover, if the monitoring equipment wants to obtain the traffic of a specific destination port or a specified protocol, traffic mirroring and optical splitters are difficult to complete the task
