  • Provider backbone bridging—provider backbone transport internetworking
    Patent number: 9036641
    Abstract: An Ethernet virtual switched sub-network (VSS) is implemented as a virtual hub and spoke architecture overlaid on hub and spoke connectivity built of a combination of Provider Backbone Transport (spokes) and a provider backbone bridged sub-network (hub). Multiple VSS instances are multiplexed over top of the PBT/PBB infrastructure. A loop free resilient Ethernet carrier network is provided by interconnecting Provider Edge nodes through access sub-networks to Provider Tandems to form Provider Backbone Transports spokes with a distributed switch architecture of the Provider Backbone Bridged hub sub-network. Provider Backbone transport protection groups may be formed from the Provider Edge to diversely homed Provider Tandems by defining working and protection trunks through the access sub-network.

  • Communicating data units in a communications network that provides failure protection
    Patent number: 9025441
    Abstract: A node comprises a first communications interface to a customer network element, where the first communications interface is part of a group of communications interfaces to the customer network element to provide failover support. The node further includes a network interface to communicate over a trunk group to other nodes, where the trunk group includes a primary trunk and a secondary trunk. Just one of the primary and secondary trunks is active for communicating data units.

  • COMMUNICATING DATA UNITS IN A COMMUNICATIONS NETWORK THAT PROVIDES FAILURE PROTECTION
    Publication number: 20130286816
    Abstract: A node comprises a first communications interface to a customer network element, where the first communications interface is part of a group of communications interfaces to the customer network element to provide failover support. The node further includes a network interface to communicate over a trunk group to other nodes, where the trunk group includes a primary trunk and a secondary trunk. Just one of the primary and secondary trunks is active for communicating data units.
