Problems solved by technology

[0003] However, the interface board is connected to other devices through non-Ethernet interfaces (such as E1 interface, T1 interface, asynchronous serial port, synchronous serial port, AM (Analog Modem, analog modem) interface, etc.), and the transmission rate of the non-Ethernet interface is relatively slow, such as The transmission rate is 100M level. Therefore, the rate at which the main control board sends data to the interface board does not match the rate at which the interface board sends data to other devices. As a result, after the interface board receives a large amount of data through the Ethernet interface, the A small amount of data is sent, resulting in packet loss

Abstract

This application provides a data transmission method, device, and network device. This method includes: the interface board and logical channel corresponding to the first data to be sent;The first data adds the head information, obtains the second data, and stores the second data to the buffer corresponding to the logical channel; the header information includes the interface board logo and logical channel logo;The second data, and obtain the interface board logo and logical channel logo from the head information of the second data read, remove the head information of the read second data, get the first data, and send the first data obtained toThe interface board identifies the interface board.Through the technical solution of this application, the problem of incomparable to the interface board rate can be solved to avoid the problem of packet loss of the interface board.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, device and network equipment. Background technique [0002] Network devices (such as routers, switches, etc.) usually include a main control board and an interface board, and the main control board is connected to the interface board through an Ethernet interface. Since the transmission rate of the Ethernet interface is very fast, such as the transmission rate of the GE level, by using The Ethernet interface can reduce the CPU (Central Processing Unit, central processing unit) occupation, improve the concurrency of multi-core CPUs, and the main control board will not become a performance bottleneck. [0003] However, the interface board is connected to other devices through non-Ethernet interfaces (such as E1 interface, T1 interface, asynchronous serial port, synchronous serial port, AM (Analog Modem, analog modem) interface, etc.),...
