Abstract: Disclosed herein are systems, methods, and computer readable media for modifying IP backbone link weights such that multicast traffic and unicast traffic will not travel on a same path between nodes. The method comprises assigning link weights to nodes within an IP backbone such that multicast forwarding paths and unicast forwarding paths are failure disjoint, and delivering undelivered multicast packets using IP unicast encapsulation to the loopback address of next hop router on a multicast tree upon link/interface failure.

Abstract: Aspects of the subject disclosure may include, for example, a broadcast services platform includes a memory that stores operational instructions. A processor executes the operational instructions to: receive user data, the user data including a list of users and performance metric data corresponding to individual ones of the users; sort the list of the users in order of the performance metric data to generate a sorted list of the users; partition the sorted list of the users to generate a plurality of user groups; and generate network resource allocation data that allocates network resources to provide broadcast services to the users. Other embodiments are disclosed.

Abstract: A method and apparatus for providing a route recommendation are disclosed. For example, the method obtains network topology information, wherein the network topology information comprises a plurality of underlying subnetwork types for a network. The method creates a cost model for the network, and receives a request from a user for a connection to be supported by the network. The method provides the route recommendation for supporting the connection by applying the cost model.
