    摘要: Ethernet nodes, interconnected logically or physically to construct a closed loop, may be controlled using a control protocol that governs placement of blocks on the ring. The control protocol allows one of the nodes to be designated as a root node in normal operation. The root node will block data traffic on one of its ports on the ring to prevent a forwarding loop from being created on the ring. Each node on the ring performs link level connectivity detection and, upon detection of a failure, will send out a Failure Indication Message (FIM). When a node receives a FIM, it will flush its forwarding database associated with the ring and, if it is the root node, will remove the data block on the port. When the failure recovers, the nodes adjacent the failure will transmit a recovery indication message to allow the ring to revert to its normal state.

    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: Described are a system and method for identifying private resources associated with a communications network. A structured address format is defined having a plurality of character positions. Each character position is associated generally with a property of a managed resource in the communications network. A structured private address, constructed according to the structured address format, is assigned to the managed resource. Each character position of the assigned structured address has a value that identifies a specific instance of the property of the managed resource associated with that character position. Operations Systems Support (OSS) gives a common name to the managed resource and maintains an association between the common name and the structured address. The structured address format can follow a four-byte dotted decimal notation similar to IPv4 addresses. For addresses following this format, the OSS can use standard domain name system services to translate between common names and structured addresses.

    摘要: Described are a system and method for managing a service transported over a transport network between first and second service termination points. Packet traffic associated with the service is received at a service termination point connected to the transport network. Performance of the packet traffic is measured at the service termination point. The measured performance of the packet traffic and the service are correlated to produce a performance of service (PoS) service metric. Based on the PoS service metric, other service metrics associated with the service are correlated, including a rate of service (RoS) service metric and availability of service (AoS) service metric. These service metrics can be used to develop service level agreement (SLA) and service level metrics that define the operation of the service and operation of the network supporting those services.

    摘要: An optical network and method for managing a service across an optical network over a dedicated circuit between first and second service termination points include generating a service performance report message (PRM) at each service termination point. Each service PRM has service-specific information related to a performance of the service as determined by the service termination point generating that service PRM. Each service PRM identifies the service to which the service-specific information in that service PRM pertains. Each service termination point transmits the service PRM generated by that service termination point across the optical network over the dedicated circuit to the other service termination point through a service management channel of an optical transport facility. Either of the first and second service termination points is accessed to evaluate an end-to-end performance of the service based on a comparison of the service PRM generated by the first service termination point with the service PRM generated by the second service termination point.

    摘要: Described are a system and method for managing a service transported over a transport network. Service traffic is transmitted from a first network element to a second network element over a transport network. If one of the network elements detects a condition occurring in the transport network, the network element determines each service affected by the condition. Service traffic performance is measured at each of the first and second network elements. Each network element correlates its measure service traffic performance and the service to produce a performance of service (PoS) service metric. Each network element transmits its measured PoS service metric to the other network element over a service management channel. This enables each network element to correlate both performance (SPC) and fault (SFC) for both near and far end service metrics and enables a complete end to end service definition in support of a service level agreement (SLA).

    摘要: Systems and methods are provided for a multi-floor and/or multi-site distributed switch. As video applications such as “video on demand” (VoD) start to become more used by the general public and desire for combining networks capable of carrying voice, data, internet and video increases, service providers are requiring broadband networking capabilities that require new scaleable infrastructure solutions. Existing network technologies are not flexible enough to deliver broadband traffic required for each floor of a multi-floor network data center (NDC) or multiple NDCs connected in a ring. Conventional solutions involve direct cabling from each floor to a common room on one floor of the site. Embodiments of the present invention provide for a distributed switch including a plurality of switching elements on different floors/sites that is non-blocking under defined traffic conditions. By understanding some key dynamics of the NDC, including the attributes of the services being implemented and what functionality exists on each floor, the distributed switch is designed to handle a capacity much greater (>>3×) than independent monolithic switching elements on each floor joining in a “meet-me” room.

    摘要: Described are a system and method for establishing zone-based pricing for services transported over connectionless and connection-oriented networks. The connectivity network supporting the service is partitioned into one or more zones. A node connected to a packet transport network receives a packet associated with the service. The packet has information that is used to identify one of the zones of the connectivity network to which the packet can be transmitted. Service providers are thus able to use zoning to apply a pricing structure for services traditionally lacking distance-based pricing, such as Ethernet, Storage, and Internet Protocol services.

    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.
