Title: METHOD AND APPARATUS FOR MULTIPOINT TRUNKING
Abstract:
Multipoint trunking is effected among a plurality of network devices (20, 22, 24) connected by a trunk (10) comprising at least two physical links (12, 14, 16). A trunk control message protocol assures that message traffic may be delivered to the respective devices (20, 22, 24) over the individual links (12, 14, 16) of the trunk (10) prior to inclusion of the respective links (12, 14, 16) as active links in the trunk (10). The trunk (10) acts as a single network port (28, 30, 32) for each of the devices (20, 22, 24) and is layered over a plurality of media access control ports (38, 40, 42, 44, 46, 48, 50, 52, 54) which interface to the respective links (12, 14, 16).
