Problems solved by technology

The increase of source IP address entries will lead to the decrease of destination IP address entries, which will affect the packet forwarding service
And in the strict mode, it is necessary to look up another table entry through the next hop index obtained from the source IP, and compare whether the incoming interface meets expectations, and the packet forwarding process is complicated.

Abstract

The invention provides a unicast message processing method, and the method comprises the steps: receiving a unicast message, and obtaining a source IP address carried in the unicast message; determining an incoming interface of the unicast message; if the URPF mode of the ingress interface is started, obtaining a preset strategy in the ACL according to the type of the started URPF mode, and processing the unicast message according to the source IP address, the ingress interface and the strategy; according to the embodiment of the invention, the incoming interface of the unicast message and the URPF mode type are taken as consideration factors of message forwarding, so that source IP address information does not need to be stored in a routing table, the resources of the routing table are not occupied, the consumption of the resources of the routing table is reduced, and the message forwarding process in the URPF mode is simplified; in a strict mode, the step of searching the next hop index according to the source IP address can be omitted when the message is forwarded, a table look-up process is saved, and the message forwarding efficiency is improved. The invention further provides unicast message processing equipment, computer equipment and a readable medium.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a method, device, computer equipment and readable medium for processing unicast messages. Background technique [0002] The rapid development of IP (Internet Protocol, Internet Protocol) technology has greatly enriched people's material and cultural life, and the level of network development has also become an important symbol to measure a country's strength and modernization. The advantages of IP network openness and ease of operation also introduce various risks. A common network attack method is: the attacker uses the method of changing the source IP address to attack other devices, that is, source IP address spoofing. [0003] For source IP address spoofing, a defense technology has emerged: Unicast ReversePath Forwarding (URPF). More strictly, while confirming the existence of the entry, it also checks whether the entry of the message is correct. If the ...
