Data message transmission method and device, and machine readable storage medium

Abstract

The invention provides a data message transmission method, a data message transmission device and a machine readable storage medium. The method comprises the steps of after a data message is received,querying a first FIB table via a target address of the data message; if the FIB table does not have a forwarding table item corresponding to the target address, sending a request message carrying thetarget address to computing equipment, wherein the request message is used for allowing the computing equipment to query the forwarding table item corresponding to the target address from the secondFIB table of the computing equipment, and returning the queried forwarding table item; and receiving forwarding table item corresponding to the target address sent by the computing equipment, storingthe received forwarding table item into the first FIB table, and using the received forwarding table item to send the data message. According to the technical scheme provided by the invention, the processing pressure of the network equipment can be relieved, the CPU resources of the network equipment can be saved, the problem of high CPU utilization rate is avoided, and the stability of the network equipment is improved. The utilization rate of the table item resources is improved, and the service experience of the user is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data message transmission method, device and machine-readable storage medium. Background technique [0002] A network device (such as a router) usually maintains a routing table and a FIB (Forwarding Information Base, forwarding information base) table. The routing table is used to store all routes. The network device can optimize the routes in the routing table and download the preferred routes Send to the FIB table to guide the forwarding of the message through the FIB table. Wherein, each forwarding entry in the FIB table may include: the corresponding relationship between the destination IP address and the outgoing interface, so that when a message matching the destination IP address is received, it can be forwarded through the outgoing interface. [0003] Due to the limited resources of the FIB table of the network device, that is, only a certain number of ...

AI Technical Summary

Problems solved by technology

[0003] Due to the limited resources of the FIB table of the network device, that is, only a certain number of forwarding table entries can be stored. Therefore, when the number of forwarding table entries exceeds the resource limit, the preferred route of the routing table cannot be delivered to the FIB table, resulting in business interruption

When the number of routes is large, the process of optimizing the routes in the routing table and sending the preferred routes to the FIB table will cause a lot of processing pressure on the network equipment, and the CPU (Central Processing Unit, central processing unit) usage rate High, affecting the stability of network equipment
