For over a decade Dr. Lavian served as a principal scientist, architect and senior software engineer at Nortel Networks, where he designed software for switches, routers, and network communications devices and developed systems and architectures for managing them. Similarly, his doctorate in computer science from UC Berkeley focused on communication networks. Routing and switching are thus a natural fit for his expert witness practice.
There are cases where analyzing the behaviors of packet switching and routing is an integral part of the litigation. Furthermore, there is a need to understand networking principles, routing algorithms, software and hardware architectures, ASIC, firmware, high-speed backplanes, control plane, data plane, blocking and none-blocking architectures, priority queuing, time-to-live, packet addressing, routing and switching table structures, just to name a few. Dr. Lavian has both the academic background as well as industry experience to analyze and review the technical aspects of routing and switching for patent validity or infringement, and if required in the broader contexts of cloud architectures, Internet protocols, wireless networking and unified communications.
