摘要： In a communication apparatus, a receive data processor receives data and retrieves a group data record corresponding to the received data out of a group data memory. A forwarding processor forwards the received data according to the group data record retrieved by the receive data processor. The group data memory stores group data records which associate protection group identifiers with path selection data. The protection group identifiers each identify a protection group that provides logical paths constituting a redundant logical path for transporting a group of data, and their corresponding path selection data specifies which logical path to use to forward data in that protection group.

摘要： A communication apparatus that performs instant switchover from working links to backup links. The communication apparatus has a plurality of output interfaces each comprising a set of physical links constituting a different portion of a logical link. Aggregate destination management data is provided to define which physical links to use to forward frames. Upon receipt of a frame, a frame distributor consults the aggregate destination management data to select an output interface and its physical links for use in transmitting the received frame, from among the physical links constituting the logical link. When a switchover command is received, the frame distributor performs switchover from the current physical links to other physical links belonging to another output interface.

摘要： 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.
