    摘要: In a provider backbone—traffic engineering network, a method and a bridge node are provided for setting up path between edge bridges connected to customer premises. A first edge bridge advertises towards peer edge bridges a tuple comprising a port identity and a layer two address. When it needs to set up a path towards the first edge bridge, one of the peer edge bridges uses information in the tuple to compute a path label.

    摘要: Problems caused by Internet Protocol datagram fragmentation are solved by creating a session context for the datagram fragments without actually reassembling the datagram from its fragments. The session context enables treatment of the datagram without actually reassembling it. Processing fragments can be followed by forwarding the processed fragments to another node that can further fragment the IP datagram.

    摘要: A method that improves multi-area routed Ethernet network design, in which multipath implementation in each of the areas is independent of each other area to allow optimal network design in each area. The network implements a shortest path bridging medium access control (SPBM) protocol. The areas include a Level 2 (L2) routing area coupled to a Level 1 (L1) routing area via multiple area border bridges (ABBs). The L1 routing area including a backbone edge bridge (BEB) coupled to the ABBs via multiple L1 multipath instances identified by respective backbone VLAN identifiers (B-VIDs). The ABBs receive an advertisement from the BEB that indicates a set of BEB identifiers, each of which identifies the BEB and is associated with a respective B-VID. Each of the BEB identifiers is unique. The ABBs also advertise into the L2 routing area, and translate the B-VIDs based on service identifiers for frames transiting the ABBs.

    摘要: Exemplary embodiments provide for methods and systems that enable frame generation by fields taken from various queues. Protocol control can also or alternatively be distributed so that one or more header fields can be generated separately from other portions of a frame, e.g., the payload. The one or more header fields can be entered into queues from which they are taken to generate frames.

The one or more optical components are operable to process optical signals between the first and second optical physical interfaces. The optical physical interface module may be provided at the edge of a circuit board so that the circuit board has an optical interface for external communication. The optical physical interface module may be a stand-alone module or integrated into a connector of an optical cable, among other configurations.
