    摘要： A system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) domain includes at least two Backbone Edge Bridges (BEBs) of the PLSB domain. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path in the PLSB domain. An inter-node trunk is provided in the PLSB domain for interconnecting the BEBs. A phantom node is defined in the PLSB domain and is notionally located on the inter-node trunk. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress packet destined for the client system is forwarded to the client system through the connection in the first network domain.

    摘要： A method system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) network domain. At least two Backbone Edge Bridges (BEBs) of the PLSB domain 20 are provided. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path defined within the PLSB domain 20. An inter-node trunk is provided in the PLSB domain 20 for interconnecting the at least two BEBs. A phantom node is defined in the PLSB domain 20. The phantom node has a unique address in the PLSB domain 20 and is notionally located on the inter-node trunk one hop from each of the BEBs. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress subscriber packet destined for the client system is forwarded to the client system through the connection in the first network domain.

    摘要： A system for increasing the call capacity of an access point in a WLAN, allowing the number of WLAN phones that can be supported to be increased. The system determines whether a maximum total voice path delay would be exceeded if the packetization delay is increased for packets in a call. In the event that the packetization delay can be increased without the total delay exceeding the maximum delay, the disclosed system increases the size of packets used in the call, if all participating devices can process the increased packet size. The maximum delay may be predetermined, and reflect a maximum delay that cannot be exceeded without adversely impacting the voice quality of a call. If the two end points for a call are determined to be physically “local” to each other, packetization delay for the call may be increased based on the assumption that the increased packetization delay will not decrease the voice quality of the call.

    摘要： A virtual private network is provided across a Provider Link State Bridging (PLSB) network between a first node connected to a private LAN and a second node connected to a roaming device. The roaming device is authenticated. A successful authentication results in a Service Identifier for the VPN being sent to the second node. Connectivity between members of the VPN service instance is maintained as part of the PLSB Link State process for forwarding table maintenance, rather than by any form of explicit signalling. A single Customer Virtual Bridge/Virtual Switch Instance can be located at the first node to provide point-to-point connectivity to each roaming device. A virtual Residential Gateway function can be combined with the Customer Virtual Bridge/Virtual Switch Instance.

    摘要： The downstream IP packets of uni-cast services, such as Internet Access or Voice over IP network, are transported over the pseudo wire from service provider nodes at the metro hub to the access edge, whereupon they are converted to be transported on the first mile technology, such as a DSL loop, that serves the subscriber's residence. A television service provider delivers the collection of television channels through the regional network to an intermediate node, herein called the metro edge device. The function of the metro edge for downstream uni-cast traffic is to de-multiplex the downstream pseudo-wires coming on packet trunks from metro hubs, into a greater number of packet trunks leading to access edges. In this invention the metro edge device is operable to unicast individual selected channels to the subscriber's residence by adding copies of the IP packets of the selected channels into the downstream flow of packets in the subscriber's pseudo wire.
