Abstract:
In a system comprising first and second packet switches interconnected via a primary interconnect path, the packet switches each including a plurality of device ports, the packet switches adapted to exchange a plurality of packet streams including voice packets and non-voice packets, the voice packets having a higher priority than the non-voice packets, a method comprising:connecting at least one device port of the first switch to at least one device port of the second switch, thereby forming a secondary interconnect path; upon identifying any voice packets at one of the packet switches destined for the other of the packet switches, exchanging only said voice packets between the first and second packet switches using the secondary interconnect path; and upon identifying any non-voice packets at one of the packet switches destined for the other of the packet switches, exchanging said non-voice packets between the first and second packet switches using the primary interconnect path.
