Abstract

A method and apparatus provide reserved bandwidth and QOS/COS virtual circuit connections in a network using both conventional and novel reservation protocols and frame formats. An apparatus according to the invention includes an enterprise control point that communicates with switches via a reserved signaling channel. The switches have been upgraded or replaced to include enhanced functionality. The enhanced switched detect packets that include requests for reserved connections according to existing reservation protocols such as RSVP and IEEE 802.1P/Q.
Such detected packets are forwarded to the enterprise control point for processing via a reserved signaling channel.
The enterprise control point identifies a path within the network that can satisfy the requested QOS/COS and reserves the requested resources all along the path from beginning to end. A method according to the invention includes detecting packets that include requests for reserved connections according to existing reservation protocols such as RSVP
and IEEE 802.1P/Q, forwarding detected packets to an enterprise control point for processing via a reserved signaling channel, identifying a path within the network that can satisfy the requested QOS/COS and reserving the requested resources all along the path from beginning to end.
