Abstract

A network element for a virtual path ring network is provided. The network element includes a first ring interface module with a ring input and a ring output. Further, the network element includes a second ring interface module with a ring input and a ring output. A first bus is coupled to the first ring interface. A second bus is coupled to the second ring interface. The first and second ring interface modules each include a switch fabric that passes packets from the ring input of the interface module to its ring output for packets with a destination address for an endpoint associated with another network element. The switch fabrics of the first and second ring interfaces further pass packets from the ring input to the first and second buses, respectively, for packets with destination addresses for endpoints that are associated with the network element. An access interface module is coupled to the first and second buses that adds and drops traffic to and from the ring network.
