摘要： A communication system comprises a plurality of packet rings, each composed of a plurality of node devices, the node devices each transmitting and receiving a packet and being interconnected in a ring; two of the packet rings being interconnected via a pair of node devices each in each of the packet rings; the communication system further comprising: a table having recorded therein the correspondence between inter-ring service classes set between the packet rings and intra-ring service classes set in each packet ring; wherein the packet transferred in the packet ring includes information on the intra-ring service classes, as intra-ring header information, and information on the inter-ring service class, as inter-ring header information, the inter-ring service class(es) being correlated with the intra-ring service class(es), and being determined based on the table; the intra-ring header information being deleted when the packet is transferred from one of the packet rings to another.
