A message transmission method and device

Abstract

The present invention provides a message transmission method and device. The method includes: a central processing unit obtains a plurality of aggregation routes corresponding to non-aggregation routes, determines a forwarding chip corresponding to the aggregation routes, and sends the plurality of non-aggregation routes to the forwarding chip. The chip sends the aggregation route to other forwarding chips other than the forwarding chip; when the forwarding chip receives the message, it obtains the route corresponding to the message; when the route corresponding to the message is a non-aggregating route, the forwarding chip uses the The ARP entry corresponding to the route determines that the forwarding chip sends the message, and uses the ARP entry corresponding to the non-aggregation route to send the message; when the route corresponding to the message is the aggregation route, the forwarding chip uses the ARP entry corresponding to the aggregation route to determine The message is sent by other forwarding chips, and the message is sent to other forwarding chips by using the ARP entry corresponding to the aggregation route. Through the technical solution of the present invention, resources of all forwarding chips can be utilized, and the number of routes that can be stored by network equipment is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message transmission method and device. Background technique [0002] During the process of transmitting a packet from a source device to a destination device, routing (routing) is used to determine a transmission path between the source device and the destination device. When a network device (such as a router, etc.) receives a packet, it forwards the packet based on a route, so as to realize network interconnection. The network device may support protocols such as TCP (Transmission Control Protocol, Transmission Control Protocol) / IP (Internet Protocol, Internet Protocol). Network devices usually connect two or more logical ports identified by IP subnets or point-to-point protocols, and have at least one physical port. Network devices reflect the current network topology by dynamically maintaining routing tables, and maintain routing tables by exchanging routing and l...

AI Technical Summary

Problems solved by technology

[0003] Since the number of routes that the forwarding chip can store is limited by the specifications of the forwarding chip, when the number of routes established by the network device is large, the forwarding chip cannot store all the routes, and when the network device delivers routes to the forwarding chip, it cannot deliver all the routes to the chip

For example, if the forwarding chip can store 100,000 routes and the number of routes established by the network device is 1 million, the network device can only deliver 100,000 routes to the forwarding chip, and the other 900,000 routes cannot be delivered to forwarding chip
