A router design method with shared routing control logic

Abstract

The invention discloses a router design method for sharing routing control logic, and relates to the field of router design. This method carries out master-slave division with the router in the control area, makes a plurality of routers logically form a super router (has a routing control logic and a plurality of high-speed forwarding logics that are distributed in different physical locations in the control area); The routing control logic sends control and query data packets to the high-speed forwarding logic of multiple slave routers, and the high-speed forwarding logic of the slave router parses the instruction data packets and performs software and hardware configuration (mainly related to forwarding table information, etc.) by deploying interface functions. The router's routing control logic goes to sleep. The method simplifies the network structure, reduces deployment cost and router energy consumption.

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 ...
