Router design method for sharing routing control logic

Abstract

The invention discloses a router design method for sharing a routing control logic, and relates to the field of router design. According to the method, routers in a control region are divided into a master router and slave routers, so that a plurality of routers logically constitute an X-router (one routing control logic and a plurality of high-speed forwarding logics distributed at different physical places exist in the control region); the routing control logic of the master router sends control and inquiry data packets to the high-speed forwarding logics of a plurality of slave routers, the high-speed forwarding logics of the slave routers carry out parsing and carry out software and hardware configuration (which mainly relates to forwarding table information and the like) on the instruction data packets by a deployment interface function, and the routing control logics of the slave routers enter a dormant state. According to the method, a network structure is simplified, and deployment cost and router energy consumption are reduced.

Description

technical field

[0001] The invention relates to a design method of a novel router, in particular to a design method allowing routers to share routing control logic to reduce network management complexity and energy consumption. Background technique

[0002] The router is mainly composed of two subsystems, routing control logic and high-speed forwarding logic. The former is used to advertise and collect network routing information, and calculate neighbor tables and global routing tables according to algorithms, and finally generate forwarding tables for different network ports (network segments) ; The latter is responsible for processing the data packet (calculating the checksum, updating the MAC address, etc.), and forwarding the data packet at high speed according to the content of the forwarding table. The routing control logic subsystem is responsible for a large amount of calculations and low processing delay requirements, while the high-speed forwarding logic subsystem ...
