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.
