Hardware routing table management method and device and communication equipment

Abstract

The invention provides a hardware routing table management method and a hardware routing table management device and communication equipment. The method comprises the following steps of: copying routing information, informed by a hardware forwarding device, into a software routing table by using a protocol control device, and configuring the routing information into a hardware routing table; and monitoring the hardware routing table and performing aging and / or recovery treatment on the routing information in the hardware routing table according to a monitoring result. The device comprises a copying module and an aging module and / or a recovery module. The communication equipment provided by the invention comprises the protocol control device, the hardware forwarding device and the hardwarerouting table management device. The method and the device and the communication equipment solve the problem of limited capacity of the hardware routing table in the prior art, expand network capacity and optimize network performance on the premise of not increasing hardware cost or network topology, and make effective and full use of hardware and software resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a hardware routing table management method, device and communication equipment. Background technique [0002] The three-layer switch based on hardware forwarding is mainly composed of two parts, the protocol control plane and the hardware forwarding plane, that is, the protocol control device and the hardware forwarding device. Among them, the protocol control plane is mainly used to run various protocols, conduct route learning through the interaction of protocol messages, and notify the learned routing information to the hardware forwarding plane; and the hardware forwarding plane is composed of one or more switching chips, When the network data flow arrives at the switch, routing lookup and wire-speed forwarding are completed on the switching chip. The routing information of the protocol control plane is stored in the software database. The capacity of the software data...
