  • System for defining multicast message distribution paths having overlapping virtual connections in ATM networks and assigning identical labels to overlapping portions of the virtual channels
    Patent number: 5684961
    Abstract: In a communication network having a set of hosts and switch based label swapping communication nodes, each node has a control processor that is also a host that sends and receives messages via the switching apparatus in its associated node. At least one of the hosts includes a distribution tree set up procedure. That procedure stores source and destination data designating a set of source hosts and a set of destination hosts in the communication network, and defines a distribution tree of virtual connections. The designated source hosts and destination hosts may include the control processors of some or all the network nodes. The defined virtual connections include a virtual connection from each designated source host to all of the designated destination hosts, and message labels for all messages sent by the source hosts to be routed to the destination nodes.
