Problems solved by technology

[0005] However, a large number of user terminals are usually gathered in the network. When these user terminals communicate with each other, a large number of fast forwarding tables will be established in the network equipment, resulting in insufficient memory of the network equipment, affecting the performance of the network equipment, and even causing the equipment to hang up. die or restart

Abstract

The embodiment of the invention provides a method and a device for establishing a fast forwarding table, and belongs to the technical field of communication. The method comprises the following steps: when a communication message is received, according to a service matching rule set according to a message processing strategy, determining a target service matched with the communication message, if the fast forwarding table corresponding to the communication message is not stored locally, obtaining a preset target priority of the target service, according to a corresponding relation between a preset priority and a resource utilization rate threshold value, obtaining a resource utilization rate; and determining a target resource utilization rate threshold value corresponding to the target priority, judging whether the current resource utilization rate exceeds the target resource utilization rate threshold value, and if the current resource utilization rate does not exceed the target resource utilization rate threshold value, establishing a fast forwarding table corresponding to the communication message. By adopting the method and the device, the memory pressure of the network equipment can be reduced, and the network equipment is prevented from being suspended or restarted.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a method and device for establishing a fast forwarding table. Background technique [0002] At present, network devices are usually provided in the network, and the network devices include access switches, aggregation switches and core switches. Among them, the user terminal can be connected to the access switch, the access switch is connected to the core switch through the aggregation switch, and the core switch is connected to the external network through the egress router, so as to realize the data transmission between the user terminal and the external network. [0003] A network device (such as a core switch) is usually provided with a fast forwarding function, and the process of processing packets by the network device is as follows. [0004] When a network device receives a communication message, if the fast forwarding table corresponding to the communica...
