Abstract
There is provided a packet transmission device which comprises a packet transfer processing part and a control part. The packet transfer processing part includes a table memory comprising a path selection table, a link status table, and a node status table. In these tables, information of each of paths, links, and nodes are stored and linked each other. A link/node status monitoring part in the control part monitors a packet outputted from the packet transfer processing part transmission and detects a fault occurred in a transmission of the packet. The fault is reflected on the information of paths in the tables only by updating the information of links and nodes and the path for packets outputted from the device is assigned in a short time.
