摘要： A system and method for providing communication connection resilience between a mobile subscriber device and a network, such as the Internet. In one aspect, the invention provides improved communication connection resilience by using multiple nodes in multiple chassis to create redundant communication routes and to provide redundancy for control data relating to a mobile subscriber device. In one embodiment, a first node resides in a first chassis and a second node resides in a second chassis, and when an active communication link between the mobile subscriber device and the network via the first node becomes disrupted, the active communication link is rerouted such that data is communicated between the mobile subscriber device and the network via both of the first and second nodes.

摘要： 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.
