Latest Patents

One of his latest patents is titled "Path provisioning for service level agreements in differentiated service networks." This invention presents a system and method for path provisioning in a network that calculates an optimal path using a greedy algorithm with backtracking to execute service level agreements (SLAs). The sequential path shifting (SPS) algorithm compares the cost of a suboptimal path for a present quadruplet with the cost of switching a path for a previous quadruplet configured for alteration. If the present path is already optimal, no further operations are performed. However, if the cost of a suboptimal path exceeds the switching cost, the previous path is altered to configure an optimal path for the present quadruplet. The capacity of the network is iteratively adjusted to accommodate path selection, making this system applicable to differentiated services networks or optical networks.

Another significant patent is "Connection splitting: an efficient way of reducing call blocking in ATM." This technique addresses ATM call blocking by splitting wideband connections into multiple low-bandwidth sub-connections and routing them independently through the network. This innovative approach utilizes fragmented network bandwidth to support calls that would otherwise be blocked by conventional routing. The patent includes a detailed cell-level design for the split scheduling algorithms and provides a system for implementing splitting without requiring any protocol changes within the network, modifying control plane protocols only within the end-stations.
