  • System and method using switch fabric to support redundant network ports
    Patent number: 7170854
    Abstract: In a method for providing protection switching in a voice-over-broadband (VOB) gateway, egress traffic is multicast from a switch fabric to a working port and to a protection port. The working port forwards the egress traffic to a network in a working mode of operation, and the protection port forwards the egress traffic to the network in a protection mode of operation. Also, the working port forwards ingress traffic to the switch fabric in the working mode of operation, and the protection port forwards the ingress traffic to the switch fabric in the protection mode of operation. In one aspect, ingress traffic is forwarded from the protection port and not from the working port in the protection mode of operation. In another aspect, the working port and the protection port share status information, and the status information is used to select between the working mode of operation and the protection mode of operation.
