Patent ID: 7974188

Claim:
A repeater for sending and receiving a routing message for changing routing information, comprising: a fault information receiver for receiving fault information sent from a first adjacent repeater which is disposed adjacent to said repeater; a repeating device for receiving a routing message from said first adjacent repeater and sending the received routing message to a second adjacent repeater which is disposed adjacent to said repeater; a repeating suppressor for analyzing the routing message from said first adjacent repeater and determining whether the routing message from said first adjacent repeater is to be sent or not; and a proxy responder for generating and sending a pseudo-routing message to said second adjacent repeater, instead of the routing message from said first adjacent repeater; wherein if said repeating suppressor judges that the routing message from said first adjacent repeater is to be sent, said repeating suppressor returns the routing message to said repeating device, and if said repeating suppressor judges that the routing message from said first adjacent repeater is not to be sent, said repeating suppressor does not return the routing message to said repeating device, and sends the result of analysis of the routing message to said fault information receiver; said repeating device sends the routing message returned from said repeating suppressor to said second adjacent repeater; said fault information receiver instructs said proxy responder to generate and send a pseudo-routing message based on the result of analysis of the routing message from said repeating suppressor or the fault information; and when instructed by said fault information receiver, said proxy responder generates the pseudo-routing message and sends the generated pseudo-routing message to said second adjacent repeater.
