LOW-ORDER NODE, NETWORK, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To effectively use network resources by providing a fault recovery control technique matching a multi-layer network.

SOLUTION: A low-order node which sends LSA packets suspends transmission of the LSA packets for a specified time. Namely, the low-order node does not send official announcement to a high-order node immediately once a fault occurs to a low-order network, but expects the low-order network to speedily recover and suspends the official announcement for the certain time to avoid route calculation which becomes ineffective.
