  • Logical port system and method
    Patent number: 8611363
    Abstract: Logical ports allow multiple customers to be connected to and to receive different services over a common physical port of a packet forwarding device. Such logical ports allow for customer separation and may be created based on VLAN ID and MPLS labels. In one embodiment, each service provided via a packet forwarding device is associated with a unique logical port. The logical port may span multiple physical ports.

  • Achieving super-fast convergence of downstream multicast traffic when forwarding connectivity changes between access and distribution switches
    Patent number: 7719959
    Abstract: In one embodiment a switch has active and standby LAYER 2 switch interfaces coupled, respectively, to device interfaces of first and second LAYER 2/LAYER 3 network devices. The active switch interface is configured to forward all egress traffic and accept all ingress traffic and the standby switch interface is configured to forward only IGMP messages and configured to block all ingress traffic.
