Self-distributed logical channel node failure restoring system
First Claim
1. A self-distributed transmission line failure restoring system including at least three nodes arbitrarily interconnected by bidirectional transmission lines, each of said nodes comprising:
- an alternate route search information transmitting unit for transmitting alternate route search information to all of said connected transmission lines when a given node is determined to be a channel terminal of a failed transmission line in accordance with failure detection information;
an alternate route connection information transmitting unit for generating alternate route connection information having anode trace and transmitting the information to a connection destination node upon receiving the alternate route search information from both channel terminal nodes connected by said failed transmission lines;
a check information transmitting unit for receiving the alternate route connection information to set an alternate route and transmitting check information having a ode trace to a connection source node through the set alternate route when said given node is determined to be a connection destination node; and
a check information receiving unit for receiving the check information to determine an alternate route of said failed transmission line when said given node is determined to be the connection source node.

Abstract
A self-distributed transmission line failure restoring system includes three nodes or more arbitrarily interconnected by bidirectional transmission lines. Each of the nodes includes an alternate route search information transmitting unit, an alternate route connection information transmitting unit, a check information transmitting unit, and a check information receiving unit. The alternate route search information transmitting unit transmits alternate route search information to all of the connected transmission lines. The alternate route connection information transmitting unit forms alternate route connection information having a node trace and transmitting the information to a connection destination node. The check information transmitting unit receives the alternate route connection information to set an alternate route and transmitting check information having a node trace to a connection source node through the set alternate route. The check information receiving unit receives the check information to determine an alternate route of a failed transmission line.
