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

The application provides a data transmission method, a data transmission device, and network equipment. The method comprises: determining an interface board and a logical channel corresponding to thefirst data to be sent; if the logical channel has the capability of transmitting the first data, adding the header information to the first data to obtain the second data, and storing the second datain a buffer corresponding to the logical channel, wherein the header information includes an interface board identifier and a logical channel identifier; reading the second data from the buffer, obtaining the interface board identifier and the logical channel identifier from the header information of the read second data, removing the header information of the read second data to obtain the firstdata, and sending the obtained first data to the interface board corresponding to the interface board identifier. The technical solution of the application is capable of solving the problem that the rates of the main control board and the interface board do not match, and avoiding the 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.),...
