First Claim
Patent Images
1. A method of determining paths in a network topology using a computer including a microprocessor, comprising:
- providing at least one source/destination pair, each pair representing a source and a destination in the topology;
providing a node list comprising a topological ordering of node identifiers representing communication nodes in the network topology;
providing at least one path connecting the source and the destination based on the node list;
selecting a source from the topology;
identifying the position of the source in the node list; and
generating at least one path from the selected source to the destination based on traversing the node list from the identified position to a first position.
