Abstract

The embodiment of the present invention discloses a message forwarding method and device, which relate to the field of data communication. In one BD, the multi-BD message sending function supported by the sending port of the network device is used to reduce the CPU overhead during message forwarding, thereby effectively improving the message forwarding performance of the CPU. The method includes: acquiring an adjacency table entry corresponding to the IP address of the next hop of the message to be forwarded, the adjacency table entry including link layer header information corresponding to the IP address of the next hop of the message to be forwarded ; respectively storing the adjacency table entry and the message to be forwarded in an idle buffer descriptor BD; sending the message to be forwarded according to the BD.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a message forwarding method and device. Background technique [0002] For network devices based on three-layer forwarding, such as routers, message forwarding performance (that is, message throughput) is a very important performance index, which determines the network layer that the network device can be suitable for. Generally speaking, , higher-level network nodes have higher requirements on packet forwarding performance, for example, devices located in the core network have higher requirements on packet forwarding performance than devices on the lower-level aggregation network. [0003] Generally speaking, improving the packet forwarding performance of a network device can be achieved by improving the hardware configuration, such as using a more advanced central processing unit (Central Processing Unit, CPU), but improving the hardware configuration means higher h...
