<p>PROBLEM TO BE SOLVED: To solve a problem such that a packet, having a reduced bandwidth due to a ling aggregation (LAG) failure, is discarded in a LAG failure occurrence section.SOLUTION: On the occurrence of the LAG failure due to a physical link failure, a relay node processes reading of a failure occurrence LAG ID, a reduced band and an effective band, triggered by the detection of connectivity abnormality at periodic LACP transmission and reception, to store into an AIS frame and transfer to an edge node. The edge node terminates and analyzes the AIS frame to grasp a failure occurrence LAG ID, a band reduction amount, and an LSP ID passing through the LAG. The edge node then refers to LSP priority to save traffic to a preset standby LSP in order from LSP having the lowest priority to the highest by the amount of the reduced band.</p> |
