DESCRIPTION:Prof. Jennifer Rexford\, Princeton University\, USA\nThe tradi
 tional view of a router is as a networking device that computes routes and
  forwards packets from one link to another. Recent technical advances in v
 irtualization enable a fresh rethinking of the relationship between router
  software and the underlying physical hardware. In this talk\, we present 
 two ways to capitalize on router virtualization to improve network reliabi
 lity and simplify network management. First\, we argue that many network-m
 anagement problems stem from the difficulty of maintaining consistency bet
 ween the physical and logical configuration of the routers. To address thi
 s problem\, we propose VROOM (Virtual ROuters On the Move)\, a new network
 -management primitive that allows (virtual) routers to freely move from on
 e physical node to another. In addition to simplifying existing network-ma
 nagement tasks like planned maintenance and service deployment\, VROOM can
  also help tackle emerging challenges such as reducing energy consumption.
  Second\, we argue that the complexity of router software leads to bugs th
 at can have serious\, network-wide consequences. To address this problem\,
  we propose the design of a bug-tolerant router (BTR) that runs multiple d
 iverse instances of routing software in parallel to detect faulty results 
 before they impact data traffic or propagate to other routers. For both VR
 OOM and BTR\, we present the design and evaluation of prototype systems ru
 nning on commodity platforms using unmodified open-source routing software
