Uniform link layer multi-protocol exchange method based on Ethernet bus

Abstract

The invention provides a uniform link layer multi-protocol exchange method based on an Ethernet bus. The method comprises the steps that virtual channels are defined, the virtual channels are made to correspond to forwarding interfaces of a routing module, the virtual channels correspond to the forwarding interfaces of the routing moduleone to one, and the routing module is configured for data routing, that is, the virtual channel is selected for data forwarding; the data transmitted through the virtual channels are received by an interface processing module on an interface plate, and are sent to corresponding interface protocol processing modules, and the different protocol processing modules correspond to different interfaces; uniform link layer multi-protocol exchange is achieved through the configured virtual channels, and comprises data sending and data receiving. According to the uniform link layer multi-protocol exchange method, interface expansion is carried out based on network exchange equipment through the interface plate, data exchange on an Ethernet link layer is completed by defining the virtual channels, the data forwarding efficiency is improved, and expansion and upgrading of the network exchange equipment are facilitated.

Description

technical field [0001] The invention relates to the technical field of device interface protocol exchange, in particular to an Ethernet bus-based unified link layer multi-protocol exchange method. Background technique [0002] Network switching equipment, as the hub connecting various communication transmission equipment, plays an important role in the communication network. With the continuous development of communication networks, the types and quantities of communication transmission equipment continue to increase, and the types of interfaces of transmission equipment are increasing. Currently commonly used interfaces are: MRC / CAN port, Ethernet port, serial port, K ​​port, E1 port, wired port, optical fiber port, etc. Different interfaces follow different protocols. Generally speaking, the serial port follows the slip protocol, the K port / E1 port follows the K port / E1 port protocol, and the Ethernet follows standard protocols such as IEEE802.3. However, in some special...

Problems solved by technology

However, in some special fields, these interface protocols of communication transmission equipment are mostly customized by the manufacturers themselves and will not be disclosed to the public. The interface protocol can be customized for different interface boards

[0003] Most of the current network switching devices use the UDP transmission protocol when connecting to the interface board, and the data transmission and exchange efficiency is low.

Moreover, even if the interface protocol is known, it is directly expanded on the hardware board through the PCIE bus, which is not conducive to the expansion and upgrade of network switching equipment.
