  • Virtual path merging in a multipoint-to-point network tunneling protocol
    Patent number: 6967955
    Abstract: A computer network includes frame- or packet-based subnetworks connected by switches, the switches being interconnected by high-capacity trunks using a connection-based data transfer protocol similar to Asynchronous Transfer Mode (ATM). Some of the trunks include a Permanent Virtual Path (PVP) trunk crossing an ATM core network, the PVP trunk including one or more bidirectional PVPs. A multipoint-to-point (MPT) protocol is used among the switches to transfer packets as groups of cells directly from “leaf”, or source, switches to “root”, or destination, switches without requiring significant routing-related processing during cell transmission.
    Type: Grant

    Date of Patent: November 22, 2005
