Latest Patents
One of his latest patents is titled "Content caching in the radio access network (RAN)." This invention presents a system and method to intercept traffic at standard interface points defined by cellular and wireless networks. It emulates the respective protocols on either side of the interception point, extracts user and application payloads within the intercepted packets, performs optimizations, and re-encapsulates the data with the same protocol for transparent delivery. The optimizations include content caching, prediction and pre-fetching of frequently used content, and content-aware transport optimizations to reduce back-haul bandwidth and improve user experience. Another significant patent is the "Burst packet scheduler for improved RAN efficiency in UMTS/HSPA networks." This method generates optimal packet workload to balance maximizing cell throughput and fairness across multiple users in UMTS/HSPA networks. The scheduler enhances the performance of existing schedulers by monitoring recent RAN bandwidth and controlling egress burst rates while delivering packets.
