CMSC 712 Distributed Algorithms and Verification:
The design and analysis of distributed systems and network protocols, from
both correctness and performance aspects. My current work is on:
Earlier work includes
(fast computation of evolution of ensemble metrics for M(t)/M(t)/. networks),
minimal latency transport protocols, scalable ToS/policy
routing testbed , link-state vs distance-vector routing.
Assertional methods for concurrent/realtime systems, particularly layered
systems as found in operating systems and networking.
Recently completed book on this topic.
TSS (Time-step simulation): a diffusion-based method to simulate
general queueing networks with state-dependent delayed feedback
(e.g., TCP/IP networks).
Provides the accuracy of packet-level simulation
at a cost several orders cheaper than simulation.
TSS for wireless networks and wired-wireless networks.
