Abstract: Systems, methods, and tangible computer-readable media are described for network routing of traffic. The system includes a source node for multicast traffic assignment across multiple networks. The source node chooses a first node and at least one different node for transmitting a message, the message to be transmitted from the source node to the first node, then to the at least one different node, then to a destination node.

Abstract: Methods and apparatus for routing mixed cast requests through a Clos-like network are disclosed. According to one aspect of the present invention, a method for processing a routing request within a network system includes computing costs associated with input links between a center stage and an input stage and computing costs associated with output links between the center stage and an output stage. The method also includes comparing the costs associated with the input links and the costs associated with the output links to identify a first input link, a first output link, and a second output link. The first output link is associated with a first center stage node and the second output link is associated with a second center stage node. The request is routed using the first input link, the first output link, and the second output link.

Abstract: A programmable call processing system (52) provides a standard call processing process (80) performing call processing according to industry standard call models, at least one database (84, 86) storing call processing data accessible by the set of standard call processing process (80), and at least one customized call logic program (92) for implementing extended subscriber features on the telecommunications switching system (10, 30). Further, an application program interface (56, 94) provides access by the at least one customized call logic program (92) to the at least one call processing database (84, 86) and further interrupting the standard call processing process (80) to execute the customized call logic program (92).

Abstract: A programmable call processing system (70) provides a standard call processing process (82) performing call processing according to industry standard call models, at least one database (84, 86) storing call processing data accessible by a set of call processing state machine process (80), and at least one customized call logic program (92) for implementing extended subscriber features on a telecommunications switching system. Further, an application program interface (94) provides access by the at least one customized call logic program (92) to the at least one call processing database (84, 86) and further interrupting the standard call processing process (82) to execute the customized call logic program (92).
