Abstract

The invention relates to an intelligent dual-redundant gigabit Ethernet processing board which is intelligent, can fast switch, and can reduce the load of a system. The board realizes the design and the fast switching of a redundant network and simultaneously can greatly reduce the load of the host of the system so as to enhance the real time, reliability and availability of the entire network system through introducing an intelligent network processing chip and locating a switching process on the board to carry out. Meanwhile, eight network switch ports are expanded on the board, thus the functions of networking and data exchanging can be conveniently and quickly carried out. A VxWorks operating system is operated on the board provided by the invention, thus the fast switching for a dual-redundant gigabit network is realized through a software switching technology; and the reinforced PCI (Peripheral Command Indicator) bus technology is adopted, thus the intelligent dual-redundant gigabit Ethernet processing board can be widely applied to industrial network environments which have higher requirements on reliability and real time.

Description

technical field [0001] The invention relates to a board, in particular to an intelligent double redundant Gigabit Ethernet processing board. Background technique [0002] The development trend of modern industrial networks has higher and higher requirements for the reliability and effectiveness of network equipment. In order to improve the reliability and effectiveness of network equipment, it is a very necessary measure to introduce dual redundancy design into network cards. When one of the dual redundant network cards fails, it can quickly switch to the other redundant backup to ensure network reliability. Since dual-network switching has high requirements for real-time performance, how to quickly realize the switching of dual redundant network cards has become a key technology. [0003] Most of the currently used dual redundant network cards are based on host software switching technology, relying on the system host to poll the link status of the dual network to achieve ...
