Problems solved by technology

With the growth of the network scale, the number of interfaces supported by network devices is increasing, and the routing information that needs to be updated is also increasing. Frequently traversing all the routes of each interface and grouping and sending packets seriously consumes processing resources and brings a lot of damage to the CPU. The number of interfaces and routes that such a node can support is quite limited, resulting in poor diffusion performance of the RIP protocol.

Embodiment Construction

[0052] For a node running the RIP protocol or RIPng protocol, the routing entries in its routing database are stable most of the time, that is, most of the time the interface enabled with the RIP protocol or RIPng protocol on the node expires when the Update timer expires. , the routing update content to be sent remains unchanged. That is to say, the routing update information found by traversing the routing database each time, and the protocol packets packaged according to the routing updating information are consistent most of the time. Therefore, in the present invention, the protocol information to be sent can be saved, and the protocol message can be encapsulated according to each sending; the encapsulated protocol message can also be saved, and the protocol message can be directly sent each time. When the protocol information to be sent changes, the protocol information is regenerated or the protocol message is re-encapsulated. In this way, during the time period when t...

Abstract

The invention discloses a method for sending protocol messages with network nodes. The method includes the following steps; protocol information is generated and stored; the stored protocol information is encapsulated into a protocol message when required conditions are met; and the protocol message is transmitted. The invention can reduce CPU time taken for transmitting protocol messages and save processing resources.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a device for sending a protocol message by a network node. Background technique [0002] As the most widely used interior gateway protocol, RIP (Routing Information Protocol, Routing Information Protocol) and its next-generation RIPng (RIP Next Generation, next-generation RIP protocol) are suitable for the transmission of routing information in autonomous systems of small similar networks. Among them, RIP is used to support the publishing and learning of IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) routes, and RIPng is used for publishing and learning IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) routes. RIP and RIPng are protocols based on a distance vector algorithm, and exchange routing information through UDP (User Datagram Protocol, User Datagram Protocol) packets. The basic mechanism of the RIPng protocol is similar to ...
