Data forwarding method and device and network equipment

Abstract

The invention provides a data forwarding method and device and network equipment. The method comprises the steps of receiving a to-be-forwarded message sent by external equipment through an input interface, and searching whether a target MAC address corresponding to a target IP address of the to-be-forwarded message exists in a virtual ARP table or not; when the target MAC address exists in the virtual ARP table, removing wide area network link encapsulation at the head of the message to be forwarded, encapsulating the message to be forwarded into an Ethernet message, sending the Ethernet message to a switching chip, and sending the Ethernet message to an output interface corresponding to the target MAC address by the switching chip; and forwarding the message to be forwarded according tothe interface type of the outgoing interface. In the scheme, the encapsulation processing of the message is realized by the interface, the operand of the processor is reduced, and the data forwardingperformance is favorably improved.

Description

technical field [0001] The present application relates to the field of data communication, in particular, to a data forwarding method, device and network equipment. Background technique [0002] At present, traditional datacom network devices such as routers and gateways all support WAN interfaces and Ethernet interfaces, and can realize the mutual forwarding of WAN data and Ethernet data. The dedicated hardware chip supports header conversion between WAN and Ethernet packets. Therefore, traditional WAN packet data forwarding usually relies on the Central Processing Unit (CPU) for processing. The analysis and processing of link headers not only consumes a lot of CPU resources but also It will increase the complexity of software processing, which will easily lead to the reduction of the entire IP data forwarding performance. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a data forwarding method, device and networ...
