A data message transmission method, device and machine-readable storage medium

Abstract

The present disclosure provides a data message transmission method, device, and machine-readable storage medium. The method includes: after receiving the data message, querying the first FIB table through the destination address of the data message; if the first FIB table is not There is a forwarding entry corresponding to the destination address, and sending a request message carrying the destination address to the computing device; the request message is used to make the computing device query the forwarding table corresponding to the destination address from the second FIB table of the computing device. post items, and return the query forwarding table items; receive the forwarding table items corresponding to the destination address sent by the computing device, store the received forwarding table items in the first FIB table, and use the received The forwarding entry sends the data packet. Through the technical solution of the present disclosure, the processing pressure of the network equipment can be reduced, the CPU resources of the network equipment can be saved, the problem of high CPU usage can be avoided, and the stability of the network equipment can be improved. Improve the utilization of table item resources and improve user service experience.

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
