Abstract

Each of hub nodes (100,101) transmits, from its ports (1,2), keep-alive frames to be broadcasted by relay nodes constituting communication media (106,107). Arrivals of the keep-alive frames are monitored at the respective ports. During a normal state, the two communication media connected to the ports (1,2) are used virtually as a single node so as to expand the communication band. During detection of a trouble, only the communication medium, which is connected to a port where no trouble has been detected, is used to continue the communication.

Description

technical field

[0001] The present invention relates to a communication system that realizes high reliability, and particularly to a communication system with high reliability that transmits data frames using a plurality of bandwidth to suppress congestion, and when a failure is detected, communication continues using only the communication path where the failure was not detected. Background technique

[0002] In recent years, computer networks have made great progress in various fields of society. They are not only widely used as communication means for information transmission by email and information disclosure by Web sites, but also play an important role as an infrastructure for providing various services. social role.

[0003] In today's society that cannot be separated from computer networks, due to accidents such as failure of devices constituting the network, cuts of communication cables, or narrowing of the communication bandwidth due to congestion, etc., events t...
