Document Type and Number:
Japanese Patent JP7091923
Kind Code:
B2
Abstract:
Transfer apparatuses perform communications for path control with a centralized control apparatus that performs centralized control from the outside of a switch cluster including the group of transfer apparatuses, through a path similar to D-plane (main signal). A packet flow controller serving as a separation unit that separates a packet for the inside of the cluster and a packet for the outside of the cluster transmitted through the similar path from each other, and an internal route engine that performs path control of obtaining a path for freely passing through a plurality of paths in the cluster are provided. The packet flow controller separates a path control packet for the inside of the cluster, and the engine performs, when a failure to communicate the path control packet for the inside thus separated occurs, path control of generating a path that bypasses a path with the failure.
