Xunet II (a wide-area ATM network) and IDLInet (a PC-based local-area ATM network). My recent work has been in two broad areas: network management and
Internet-telephony integration. My research group and I are creating the next generation of network management tools. These include tools for network discovery, monitoring, simulation, visualization, and configuration
management. We believe that these tools will allow network managers to design and maintain reliable, robust networks that provide users with macroscopic quality-of-service guarantees. We have also built in the ITX project, a testbed that allows us to rapidly create
services that span the telephone network and the Internet. These services, written entirely in Java, are constructed from four fundamental building blocks: a) IP data transport b) SIP signaling c) directory service and d) Internet-telephony gateway. My group is also working on techniques for fast simulation, scripting for
web-based applications, smart environments, web caching and application level routing.

My research interests in the area of computer networking span the spectrum from protocol design and mathematical
analysis to hands-on system implementation. Much of my work is motivated by the need for protocols and
mechanisms that provide end-to-end quality of service guarantees. This has led me to do research in the areas of traffic
manage- ment, flow and congestion control, scheduling, and pricing and to implement ideas in two experimental
