  • Multichannel ring and star networks with limited channel conversion
    Patent number: 8134939
    Abstract: A ring communication network according to an embodiment of the present invention includes a plurality of nodes in which a single one of the nodes is configured for full channel conversion and the remaining nodes, other than the single node, are configured for no channel conversion. Links with no more than W channels couple the nodes. The ring communication network also may include N nodes and links connecting the nodes for carrying data in W channels such that N?2 log2 W?1 where W is a power of 2. Each of the N nodes includes switches connected such that each channel of a first one of the links adjacent to any one of the N nodes can be switched to no more than W?1 channels of another one of the links adjacent any one node.
