• NetReplay: Supporting playback of network packets to aid targeted troubleshooting of network-induced glitches [HotMetrics09].


• New Approaches to Network Management
  • NetAna: "Complexity models" to benchmark network designs and aid network management [IMC09, NSDI09, NSDI poster]
  • NetBargain: Nash Bargaining-based management and performance tuning of wired and wireless networks [COMSNETS10, MobiCom08 Poster, Infocom07]
  • DC-Internal Traffic Management: Characterizing traffic inside datacenters, motivating the need for new approaches to managing DC-internal traffic [SIGCOMM WREN 2009].
  
  
• Network Security
  • E-mail spam: A proposal for router-level spam filtering [CEAS09] and analyzing the sources of E-mail spam [UW-Madison TR, COMSNETS10]
