    摘要: MPLS networks offering PW or VPLS services may be interconnected with Ethernet networks implemented according to 802.1ah or 802.1Qay. The MPLS network may be a core and offer services to the Ethernet access networks, or vise-versa. Additionally, a mixture of different types of access networks may be interconnected by an MPLS core or an Ethernet core. Both network interworking and service interworking are provided. OAM fault detection may be implemented via maintenance entities extending across the network or end to end depending on the combination of networks and services offered by the networks.

    摘要: A method and system for protecting a service available on a broadcast domain. A sub-domain is established within the broadcast domain. The sub-domain includes a group of nodes used to provide a communication path to the service. A primary sub-domain maintenance association and a back-up sub-domain maintenance association are monitored. The primary and sub-domain maintenance associations are a set of primary and back-up paths, respectively, representing connectivity between nodes acting as edge nodes in the sub-domain. A fault is detected within the primary sub-domain maintenance association and a switch to the back-up sub-domain maintenance association occurs.

    摘要: The present disclosure provides protection systems and methods that provide a mechanism to identify/determine when an interconnection node has been isolated (i.e. when there is no connectivity between a pair of interconnection nodes), from a data path perspective. If/when this condition exists, actions are triggered on the subtending sub-ring that essentially perform a protection switch (which causes the subtending sub-ring nodes to cleanse their forwarding tables), and, more importantly, that remove any channel blocks on the subtending sub-ring. Extensions to the ITU-T G.8032 state machine are also provided that include support for operator command interactions (e.g. DNR, force switch, manual switch, etc.). The protection systems and methods of the present disclosure enable the reliable application of ITU-T G.8032 and the like to more complex (i.e. meshed) deployment environments, among other significant advantages.

    摘要: A method and apparatus is described which enables location information associated with a client to easily be obtained by a service provider in a packet-based network. The location information may be the location of the client itself, or may be location information associated with devices in a communication facility established by the client. Location information associated with the client may be provided to services such as emergency services to facilitate fast dispatch of resources to assist the client. Location information associated with facilities of the client may be used to facilitate lawful interception of client communications. In one embodiment, the location information is obtained using information included in one of a Provider Backbone Bridge (PBB) or Provider Backbone Transport (PBT) packet.
