Abstract

The invention relates to a processing method of chain-shaped network redundancy check. Two tail ends of a chain-shaped network are provided with a head end exchanger and a tail end exchanger, and one head end exchanger or one tail end exchanger is preinstalled as block of a connection port of external network communication. When wire breakage occurs in the connection port of any exchanger in the chain-shaped network, the two exchangers adjacent to the broken connection port respectively transmit a control packet to the head end exchanger and the tail end exchanger so that the connection port originally preinstalled as the block is conducted, thus the network can rapidly restore the normal state, the head end exchanger and the tail end exchanger are used to respectively connect other chain-shaped network-external network devices or external redundancy network architectures so that network use nodes can be effectively expanded in a single network architecture, and use elasticity and compatibility of different redundancy mechanisms can exist.

Description

technical field [0001] The invention relates to a processing method for redundancy check of a chain network, especially to establish a redundancy mechanism in a chain network, wherein the connection ports of the head-end switch and the tail-end switch for external communication are respectively set to conduction and blocking. When the chain network is interrupted, the two switches adjacent to the interruption point will send control packets to the head-end switch and the tail-end switch respectively, so as to turn the preset blocked connection port into conduction, thereby Allows the network to quickly return to normal. Background technique [0002] With the rapid development of information technology and the vigorous development of Internet technology, through network technology, people can achieve the effect of communication without being restricted by region. The advancement of network technology not only adds more convenience to the public, For enterprises, it also brin...
