Unified Telecommunications

The Internet is the fundamental technology of the Information Age; more than any other technology, network communications have changed the way we live, putting the Internet at our fingertips. 

The Networking and Communications areas focus on the architecture, design, and implementation of data networks, communication systems, computer networks, and Web technologies. The Internet is the best example of interconnected computer networks that use the Internet protocol suite (TCP/IP) to communicate between many data networks, computer networks, and devices. In network communications, packet switching is the underlying mechanism for grouping data transmitted over a digital network into packets.

Dr. Lavian earned his Ph.D. from the University of California, Berkeley, in Computer Science, specializing in network communications. His research focus was on network communications, telecommunication systems, Internet protocols, and cloud computing. He has served as a scientist at UC Berkeley’s RAD Lab, and as a Technical Co-Chair for IEEE Interconnects at Stanford University.

Dr. Lavian spent over ten years working at Nortel Networks’ Research Labs, where he successfully spearheaded the development of the first network resource-scheduling service for Grid computing. He was the first to demonstrate the dynamic transatlantic allocation of 10Gbs Lambdas as a grid service, created the first wire-speed active network device on commercial hardware, and is a Senior Member of IEEE. He is an active member of ACM and IEEE-CNSV.
