Problems solved by technology

Of course, with the backup of a large amount of data, the load on the MCP increases, and eventually leads to the continuous omission of data
Since the data transmitted by the working card and the backup card are not synchronized, once the working card fails, the data transmitted by the backup card and the working card are not synchronized, resulting in the data processing of the two being out of sync, which eventually leads to unstable operation of the network equipment

Abstract

The invention provides a network device for which the 1+1 redundancy architecture is adopted. The network device comprises a master card and a slave card. The master card is communicatively connected with a terminal device and is used for receiving and processing a plurality of data sent by the terminal device. The slave card is communicatively connected with the terminal device and the master card and is used for receiving a plurality of data sent by the master card so as to backup the data and process the data together with the master card under the same state. The invention also provides a synchronous data transmission method. The master and slave cards transmit the data adopting the same sequence and principle and process the data under the same state so as to reach the synchronization of the data transmission, thus reducing the risk of omission of the data transmission and realizing the backup of the data without the MCP so as to reduce the burden of the MCP.

Description

technical field [0001] The invention relates to a network device, in particular to a network device adopting a 1+1 redundant architecture and a data synchronous transmission method thereof. Background technique [0002] With the continuous development of the network, more and more attention has been paid to the stability of network equipment. However, the emergence of redundant architecture has solved the problem of network equipment stability. Network devices use redundant architecture to back up data. When a network device fails, the network device will run the backup data to restore normal operation. [0003] Network equipment usually adopts a 1+1 redundant architecture. The 1+1 redundant architecture includes a working card and a backup card. The working card is used for the normal operation of the network equipment, and the backup card is used for data backup when the network equipment operates normally. . The working card and the backup card achieve data backup throu...
