摘要： A method and system for managing the distribution of multicast content are provided. The method involves creating a list of multicast group addresses to be made available to user units supported by a group of nodes. The list is distributed to all of the nodes in the group of nodes. Filters are created to limit the multicast content that each user unit can receive. The filters are created by referencing the list of multicast addresses previously created. The filters are distributed to the appropriate nodes and applied on customer ports.

摘要： The invention includes a method and apparatus for configuring logical connectivity for a network comprising a plurality of nodes. A method includes determining a physical topology of the network, determining a set of LSP paths based on the physical topology of the network, and determining a set of LSPs using the set of LSP paths, where the set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The physical topology is determined using information indicative of physical connectivity between nodes of the network. The set of LSP paths includes, for each pair of nodes in the network, at least two logical paths between the nodes of the node pair. The set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The full logical connectivity between the nodes of the network may be maintained in response to physical topology change events, such as addition of nodes to the network removal of nodes from the network, and the like.

摘要： Techniques for managing tiered communication services in a composite communication service are disclosed. Component communication services for providing a composite communication service are arranged into tiers in a structure of the composite communication service. The tiers and order facilitate visualization of composite communication services and assessment of the effects of events which impact a portion of a composite communication service on other portions of the composite communication service, for example. Related data structures and user interfaces are also disclosed.

摘要： A network management system, and a method of, centrally provisioning a full transport LSP mesh and a full targeted LDP signaling session mesh in support of VPN services provisioning are provided. A network management system repository tracks Provider Edge nodes (PE) having label switch router functionality, transport LSP meshes and targeted LDP session meshes. The method includes selecting PE nodes for inclusion in a node group, identifying PE node pairs, and issuing commands to paired PE nodes to commission managed transport LSPs and targeted LDP signaling sessions. The advantages are derived from the full mesh LSP content transport provisioning and targeted LDP signaling session provisioning effected in a centralized network management context enabling service providers to: assure network resiliency, assure service quality, and provide accounting, in respect of Layer-2 and Layer-3 VPN services irrespective of client side deployed infrastructure while leveraging installed infrastructure in the service provider communications network core. Additional advantages are derived from increased operations management personnel productivity while reducing the probability of human error compared to manual provisioning thereof enabling wide availability of VPN services.
