Abstract:
A method of automatically forming a virtual circuit, comprising:creating a configuration cell; passing the configuration cell to a destination node by way of at least one connective node, the configuration cell updates and validates an associated connection table, the associated connection table being capable of defining a virtual link, the virtual link being part of the virtual circuit, the virtual circuit being included in an ATM switch system having a first bi-directional port, and the virtual circuit being used to transport an ATM cell from the first bi-directional port to the destination node; generating a configuration request cell, the configuration request cell being associated with a plurality of related ATM data cells wherein the plurality of related ATM data cells define an associated communication session; and receiving the configuration request cell at the first bidirectional port included within an ATM switch, wherein the first bi-directional port includes, a configuration cell translator, a memory device having readable/writeable lookup table suitable for storing a plurality of routing parameters and a first connection table coupled to the configuration cell translator, and a configuration cell handler coupled to the memory device and the configuration cell translator, the configuration request cell includes a plurality of virtual circuit routing parameters and a plurality of quality of service (QoS) parameters associated with the virtual circuit.
