Description

A kind of multi-layer switches

Technical field:

The present invention relates to a kind of switch, more particularly, relate to a kind of multi-layer switches of the 24GE+2GE of being applied to structure.

Background technology:

Propelling and broadband Large scale construction along with the industrial application of information technology, various application constantly increase, traditional switch is difficult to realize application demands such as VOD (video request program), multimedia resources database, library automation, on the other hand, the expansion of network size, prior art can not effectively guarantee network security and suppress broadcast storm effectively, this to a great extent obstacle the development of network emerging service.

Summary of the invention:

Technical problem to be solved by this invention is: prior art is difficult to realize application demands such as VOD (video request program), multimedia resources database, library automation, on the other hand, the expansion of network size, prior art can not effectively guarantee network security and suppress broadcast storm effectively, this to a great extent obstacle the development of network emerging service.In order to solve the problems of the prior art, the invention provides a kind of multi-layer switches, form by risc processor and interface circuit, it is characterized in that described risc processor has comprised three layer interface management function modules, described three layer interface management function module-external are connected with Configuration Manager, described three layer interface management function module-external are connected with the IP module, described three layer interface management function module-external are connected with routing management module, described three layer interface management function module-external are connected with two layer interface administration modules, described three layer interface management function module-external are connected with interface Hot Spare module, and described three layer interface management function module-external are connected with SRM﹠amp; The FSU module, described each functional module of utilizing described risc processor has realized the Ethernet exchange based on 2/3/4 layer, described three layer interface management function modules and described Configuration Manager, the IP module, routing management module, two layer interface administration modules, interface Hot Spare module and SRM﹠amp; All full-duplex communication between the FSU module.

The present invention and prior art contrast, and effect is positive and tangible.In the present invention, described risc processor provides based on the exchange of 2/3/4 layer Ethernet for the user, can be as required configuration network neatly, each functional module makes the present invention have reliable and abundant managerial ability.
