摘要： Described are a system and method for managing a service across an optical network over a dedicated circuit between a first and second service termination points. Each service termination point generates a service performance report message. Each service performance report messages has information related to a performance of the service as determined by the service termination point generating the message. The service termination points exchange the service performance report messages over a service management channel to enable an assessment of the performance of the service based on the service performance report messages from both service termination points. Through access to and use of the service management channel, service providers can implement an edge management model or a core management model for measuring the performance of their services with respect to service level agreements governing those services.

摘要： A system, method and/or station that provides for spatial reuse over a resilient packet ring (RPR) network. A sublayer in a station on an RPR network tracks associations between MAC addresses of bridges on the RPR network and remote addresses in an association database. Frames addressed to a remote destination may be sent directly to the associated MAC address. A sending station uses an extended frame format for sending frames to remote addresses. If the association database in the sending station specifies an associated bridge MAC address local to the RPR network then the extended frame is addressed to the specified MAC address and flooding is disabled. If there is no association in the database, then the sending station uses a reserved group address and floods the RPR network. The sublayer “learns” associations based upon frames received from stations that also have a spatially aware sublayer.

摘要： An edge device is used to support a backbone provider bridging network to facilitate interconnection of a plurality of networks. The edge device is coupled between the backbone and a first one of the networks, and is operable to encapsulate data units received from the first network with a header, and to forward the encapsulated data unit to the backbone. The header is indicative of a tunnel that is used to support traffic from the first network to a second network over the backbone. The edge device also de-encapsulates data units received from the backbone that are destined for the first network.

摘要： Network topography may be discovered by a network element on an Ethernet network by collecting connectivity check messages periodically issued by other network elements on the network and using the information gleaned from those messages to build a topography database. Since the connectivity check messages may be link level or service instance based, the topography database may include network topography as well as service topography on the Ethernet network. Ethernet OAM loopback frames may also be used to cause network elements on the Ethernet network to issue response frames directed to the initiating network element. By collecting responses from the responding network elements, the initiating network element can build a topography database of network elements on the Ethernet network. This topography database may show the overall network topography or service instances on the network, and may provide visibility within one or more domains.
