Zied Ben Houidi, France Telecom R&D Orange Labs

Zied Ben Houidi is a last year PhD student at UPMC Sorbonne Universités doing his research at Orange Labs, France Telecom R&D, Paris, France. His research interests are in the design and the measurement of data communication networks in general. Prior to his PhD, Zied successfully completed a master degree in Computer Science from UPMC Sorbonne Universités and an engineering degree in Telecommunications from the higher engineering school of communications of Tunis.

Srikanth Sundaresan, Georgia Tech

Srikanth is a third year PhD student at the College of Computing, Georgia Tech, where he works with Professor Nick Feamster. He completed his MS in Computer Engineering at the University of Massachusetts Amherst, where his thesis was on energy aware sensor networks, and his Bachelors in Electrical Engineering at the National Institute of Technology, Jaipur, India. His current research interests include routing and management for future networks, and understanding access network performance for broadband users.

Vyautus Valancius, Georgia Institute of Technology

Vytautas Valancius is a Ph.D candidate at Georgia Institute of Technology, advised by professor Nick Feamster. His research interests include interdomain routing, Internet economics, and network virtualization. Prior to his Ph.D studies, Vytautas obtained M.S. in KTH, Sweden and worked in the networking industry as a systems engineer for 5 years, earning CCIE#14359 certification.
Abstract: The Research Forum will include:

  • Wide-Area Route Control for Distributed Services



    by Vyatautas Valancius, Georgia Tech



    Many distributed services would benefit from control over the flow of traffic to and from their users, to offer better performance and higher reliability at a reasonable cost. Unfortunately, although today's cloud-computing platforms offer elastic computing and bandwidth resources, they do not give services control over wide-area routing. We propose replacing the data center's border router with a Transit Portal (TP) that gives each service the illusion of direct connectivity to upstream ISPs, without requiring each service to deploy hardware, acquire IP address space, or negotiate contracts with ISPs.



  • Understanding Slow BGP Routing Table Transfers



    by Zied Ben Houidi, France Telecom R&D Orange Labs



    Researchers and network operators often say that BGP table transfers are slow. Despite this common knowledge, the reasons for slow BGP transfers are not well understood. This work explains BGP table transfer delays by combining BGP messages collected at a large VPN provider backbone and controlled experiments with routers of three different vendors as well as a software BGP speaker.



  • Autonomous Traffic Engineering with Self-Configuring Link Weights



    by Srikanth Sundaresan, Georgia Tech



    Network operators use traffic engineering to control the flow of traffic across their networks. Existing TE methods establish static topologies offline, either by setting link weights or by configuring paths a priori. These methods require manual configuration and may not be robust in the face of failures. Some methods also require knowledge about traffic demands and may not be able to handle traffic fluctuations. Even when changes in demand are expected, operators must manually tune network configurations to prepare for them.Because adjusting configurations is difficult to get right, we start from an extreme design point, asking instead whether it is possible to perform traffic engineering online without having to perform any a priori configuration. Our traffic engineering technique, SculpTE, adapts to changing traffic demands by automatically configuring link weights in a stable manner. SculpTE balances load across the network by continually adjusting link weights to expose lightly-loaded paths. We evaluate SculpTE using simulations on realistic ISP network topologies. Our results show that SculpTE achieves excellent load balancing, responsiveness, and stability compared to state-of-the-art TE schemes, without requiring network operators to perform any offline configuration.
