I am a faculty member with the department of Communication Systems at EPFL , Switzerland. I am currently on sabbatical leave at Sprint Advanced Technology Labs in Burlingame, California, in the IP and internetworking group . In 1996, I joined the Communication Networks Laboratory of the same institution, where I am involved in various aspects of traffic control in computer networks. I am also a Fellow of the Belgian American Educational Foundation, and I received the 1996 EPFL Doctoral Prize. Every best effort packet is marked as either green or blue.
