At Georgia Tech, we know how to network…

From Aug. 15-19, 2011, several faculty and students from Georgia Tech’s College of Computing will be at SIGCOMM 2011 to present research papers, participate in workshops, and demo emerging technologies. This site provides a quick snapshot of who we are, what we’re doing at SIGCOMM and how to contact us or join in our conversation. Check back often as we’ll be rolling out news leading up to SIGCOMM and Tweeting live from the presentations, workshops, demos and networking events.

Feel free to reach out to us through the links below, or just say hi while you’re in Toronto!

MAIN PROGRAM

“Broadband Internet Performance: A View From the Gateway”

  • Could an Internet “nutrition label” help consumers make more informed choices in selecting broadband service? Once they make that choice, they can also monitor their ISP’s performance using BISMark, a new, open-source router platform designed in Nick Feamster’s lab.
  • Nick Feamster & Srikanth Sundaresan
  • Co-authors: Walter de Donato (University of Napoli Federico II); Renata Teixeira (CNRS and UPMC Sorbonne Universités); Sam Crawford (SamKnows) & Antonio Pescape (University of Napoli Federico II)
  • Wednesday, Aug. 17, 9 a.m. to 10:30 a.m.
  • Press release

“How Many Tiers? Pricing in the Internet Transit Market”

  • Internet service providers made recent headlines with plans to start charging customers based on how much data they consume. But what if they also charged according to how far that data travels? Some already do—and it’s a smart move.
  • Nick Feamster, Vytautas Valancius, Cristian Lumezanu & Vijay Vazirani
  • Coauthor: Ramesh Johari (Stanford University)
  • Wednesday, Aug. 17, 2 p.m. to 3:30 p.m.
  • Press Release

“The Evolution of Layered Protocol Stacks Leads to
an Hourglass-Shaped Architecture”

  • As the Internet has grown and evolved, its various component networks have arranged themselves into an “hourglass”-type structure. A similar structure has evolved in certain biological systems, such as gene regulatory networks. What lessons can be gleaned from this finding—and these connections to biology—as we design the Internet of the future?
  • Constantine Dovrolis & Saamer Akhshabi
  • Wednesday, Aug. 17, 2 p.m. to 3:30 p.m.
  • Press Release

WORKSHOPS

Helping Users Shop for ISPs with Internet Nutrition Labels

  • ISPs advertise their available service plans using only generic upload and download speeds, but is this really what today’s broadband consumers need to know? If every ISP service plan carried a “nutrition label” coveying information about network metrics along many dimensions—including various aspects of throughput, latency, loss rate and jitter—users could make much more informed choices about their Internet service.
  • Nick Feamster, Keith Edwards, Beki Grinter, Srikanth Sundaresan, Anthony Tang & Marshini Chetty
  • Co-presenters: Renata Teixeira (CNRS/UPMC Sorbonne Unversites), & Walter de Donato (University of Napoli Federico II)
  • Monday, Aug. 15, 11:15 a.m. to 12:45 p.m.

Content Management in the Home

  • Nick Feamster chairs this workshop that brings together researchers and practitioners to talk about networks in homes, to share new ideas and experiences, and to discuss the challenges and important questions posed by home networks, both today and in the future.
  • “Socially-aware Gateway-based Content Sharing and Backup”
    • Jin Jiang & Claudio Casetti (Politecnico di Torino)
  • “Home Networking as a Distributed File System View”
    • Serge Defrance, Rémy Gendrot, Jean Le Roux, Gilles Stra, and Thierry Tapie (Technicolor)
  • Monday, Aug. 15, 4 p.m. to 4:45 p.m.

Getting Students Hands Dirty with Clean-Slate Networking

  • Conventional networking courses treat today’s protocols and mechanisms as fixed artifacts, rather than as part of a continually evolving system. But students must learn to think critically about Internet architecture, so what about a course that combines “clean slate” networking research with hands-on experience in analyzing, building, and extending real networks?
  • Nick Feamster
  • Co-presenter: Jennifer Rexford (Princeton University)
  • Monday, Aug. 15, 2 p.m. to 3:30 p.m.
  • Named Best Paper, ACM SIGCOMM 2011

DEMOS

LifeNet: A Flexible Ad hoc Networking Solution for Transient Environments

  • In the wake of major disasters, communications infrastructure is often destroyed or otherwise rendered inoperable, resulting in increased casualties and considerable resource wastage. LifeNet is free, open-source software that can turn consumer devices—laptops, Android phones, battery-powered routers, etc.—into an ad hoc WiFi network, making it ideal for providing connectivity in disaster-response situations.
  • Santosh Vempala, Hrushikesh Mehendale & Ashwin Paranjpe
  • Tuesday, Aug. 16, 3:30 p.m. to 5 p.m.
  • LifeNet website
  • Press Release

Communicating with Caps: Managing Usage Caps in Home Networks

  • As Internet service providers increasingly implement and impose “usage caps,” consumers need better ways to help them understand and control how devices in the home use available network resources or capacity. The researchers will demonstrate a system that allows users to monitor and manage their usage caps.
  • Hyojoon Kim, Srikanth Sundaresan, Marshini Chetty, Nick Feamster & W. Keith Edwards
  • Wednesday, Aug. 17, 3:30 p.m. to 5 p.m.

Wide-area Routing Dynamics of Malicious Networks

  • Maria Konte, Nick Feamster
  • Wednesday, Aug. 17, 3:30 p.m. to 5 p.m.
