Abstract: 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.

Abstract: 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.

Abstract: 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.
