I am a Distinguished Member of Technical Staff at Bell Laboratories, Alcatel-Lucent.

I also hold joint appointments as an adjunct faculty in the computer science department at the Illinois Institute of Technology in Chicago, and as a Research Fellow at the Interdiscplinary Center for Security and Trust at the University of Luxembourg, Luxembourg.

Since 1998, I have been working on multimedia signaling protocols, especially Session Initiation Protocol (SIP). I am also doing work on systems-related security areas for SIP in particular and Voice-over-IP (VoIP) in general. Another area of research is studying peer-to-peer (p2p) networks and distributed hash tables, especially in the context of supporting VoIP as an application and the resultant effect on the network when the peer selection process yields local peers first.

I am fairly active in the Internet Engineering Task Force (or IETF), especially in the SIP-related working groups. Besides being an author and contributor, I also co-chair two working groups: ALTO and CUSS. In Application Layer Traffic Optimization (or ALTO) working group, we are designing a protocol that will provide p2p applications with information to perform better-than-random initial peer selection. In Call Control UUI Services for SIP (or CUSS) working group, we are defining an extension to SIP for transporting user-to-user information for applications using SIP to establish multimedia sessions.

The ALTO working group attracted fair amount of press when it was in the process of being formed. When we met as a BoF session in the Dublin IETF (Aug, 2008), Heise Online printed this. Their coverage of our Minneapolis meeting resulted in this. Things have quieted down more recently as the novelty of the working group has worn off. The CUSS working group did not elicit comparable media frenzy, alas.
