Problems solved by technology

[0004] As can be seen from the above description, in the existing distributed system routing processing method, the FIB management module on the main control card is not only responsible for sending routing information to the forwarding engine on the main control card, but also responsible for the main control card and Synchronization of routing information between line cards is complicated to implement and difficult to develop
And, in the existing routing processing method, the routing management module on the main control card first sends the changed routing information to the FIB management module of the main control card, and then the FIB management module of the main control card sends the routing information to the FIB management module of the main control card. The information is sent to the FIB management module of the line card synchronously, and finally the FIB management module of the line card sends it to the forwarding engine of the line card. There are many sending processes, which is not conducive to quickly updating the forwarding on the line card when the route changes. engine

Abstract

The invention provides a route processing method in a distributed system and the distributed system, wherein the method comprises the following steps: a route management module on a master control card transmits route update information to an FIB (Forwarding Information Bank) management module on the master control card and an FIB management module on a line card; the FIB management module on the master control card generates forwarding information according to the route update information and sends the generated forwarding information to a forwarding engine on the master control card; and the FIB management module on the line card generates forwarding information according to the route update information and sends the generated forwarding information to a forwarding engine on the line card. According to the invention, the update speed of the forwarding engine is quickened when a route is changed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a routing processing method in a distributed system and a distributed system. Background technique [0002] Existing distributed systems such as distributed routers or switches include a main control card and multiple line cards, figure 1 A distributed system including only one main control card and one line card is shown, and the principles of other cases are similar. exist figure 1 Among them, the main control card includes a routing management module, a forwarding information table (FIB) management module and a forwarding engine, and the line card includes a FIB management module and a forwarding engine. [0003] based on figure 1 In the shown distributed system, the existing distributed system routing processing method includes: the routing management module of the main control card is used to update the routing information table (RIB) when the routing change...
