SDN SWITCH, AND APPLICATION AND MANAGEMENT METHOD FOR SDN SWITCH

摘要

Proposed are an SDN switch, and an application and management method for an SDN switcher. The switch comprises: an access card, a switching card, a service card and a control card, wherein the switching card is provided with a physical switching network; the service card is provided with a network processor and a cache memory module; and the control card is provided with an SDN controller. The cache memory module comprises: a cache unit, a main control unit and a redirection unit, wherein the cache unit is used for downloading and caching; the main control unit is used for the centralized management of the entire system; and the redirection unit is used for access redirection. A caching space of the cache memory module further comprises at least one of or a combination of the following: a memory component of a network processor in the service card, a storage component of a processor of the switching card, a storage component of a processor of the control card, and a storage component of a processor of the access card. The present invention improves the efficiency of responding to a request of a client, reduces the processing pressure of a server during the distribution of application contents, and improves the service processing capability of a server.
