A kind of SDN switch and the application management method of SDN switch

Abstract

The present invention proposes an SDN switch and an application management method for the SDN switch. The switch includes: an access card, a switch card, a service card and a control card, and the switch card is provided with a physical switching network; the service card is provided with a network processor and a high-speed The cache memory module, the control card is equipped with an SDN controller; the cache memory module includes: a cache unit, a main control unit and a redirection unit, the cache unit is used for downloading cache, the main control unit is used for centralized management of the entire system, and the redirection unit Used for access redirection; wherein, the cache space of the cache memory module also includes at least one or a combination of the following: the memory component of the network processor in the service card, the storage component of the processor of the switch card, the memory component of the processor of the control card The storage component and the storage component of the processor of the access card improve the efficiency of responding to client requests, reduce the processing pressure on the server when distributing application content, and improve the business processing capability of the server.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to an SDN switch and an application management method of the SDN switch. Background technique [0002] Today, with the rapid development of the Internet and mobile applications, users are increasingly dissatisfied with conventional Internet browsing, query, email and other applications, and hope to have better services in online audio, video, high-speed download, mobile terminal services and other applications. user experience. [0003] In order to alleviate the huge pressure on the egress bandwidth of network devices, in the existing technology, in addition to expanding bandwidth and controlling traffic, a cache acceleration system is also deployed to realize web download, online audio and video, P2P download, mobile APP and other applications. The automatic cache acceleration function reduces the repeated consumption of egress bandwidth by the same service requ...

Problems solved by technology

[0007] Due to this acceleration method, only the remote application content is retrieved to the local server, which reduces the delay on the network during user access. Once multiple users access concurrently, the server’s processing capacity and network forwarding capacity are still limited. Bottlenecks will also cause user access congestion and untimely server responses. Especially when dealing with online video and webcast applications, this cache acceleration method will also be unable to achieve high efficiency and high concurrency.
