    Abstract: A method and system for reducing congestion and latency in a communication system by creating a pruned forwarding set for scalable tunneling applications. The communication system provides a communication link between a mobile communication device and a network, such as the Internet. The method entails using information included within a data packet to determine a corresponding tunnel peer address, which is then resolved onto a set of paths. Each path includes respective adjacency information. A determination of whether to prune each respective path is made by using the respective adjacency information. The pruned set of paths is used to identify available paths for the communication link. By pruning in this manner, the line card being used as the home slot for a given session may also be used as the egress slot, thereby reducing congestion and latency in the communication system.
