HIGH-ORDER NODE, NETWORK, PROGRAM, AND RECORDING MEDIUM |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To effectively use network resources by providing a fault recovery control technique matching a multi-layer network. <P>SOLUTION: A high-order node having detected a fault of a low-order network suspends update of its topology information for a specified time. Namely, a high-order node does not update the topology information immediately once a fault occurs to the low-order network, but expects the low-order network to speedily recover and suspends the update of the topology information for the certain time to avoid route calculation which becomes ineffective. <P>COPYRIGHT: (C)2003,JPO</p> |
