DESCRIPTION:The Internet routing table has been growing rapidly for the pa
 st few years. Further\, as the IPv4 address space runs out\, this growth w
 ill see substantial acceleration. Such routing table growth has several ha
 rmful implications\, and led a recent Internet Architecture Board workshop
  to conclude that scaling the routing system is one of the most critical c
 hallenges of near-term Internet design. To this effect\, there have been a
  number of proposals in the IETF and research community to address the pro
 blem through novel architectures.\n\nThis talk presents ViAggre (Virtual A
 ggregation)\, a ``configuration-only'' approach to shrinking the routing t
 able on routers. ViAggre does not require any changes to router software a
 nd routing protocols and can be deployed independently and autonomously by
  any ISP. ViAggre is effectively a scalability technique that allows an IS
 P to partition the global routing table such that individual routers in th
 e ISP's network only maintain a fraction of the routing table. We find tha
 t ISPs today can use ViAggre to shrink the routing table on their routers 
 by an order of magnitude. Beyond performance results\, I will detail the d
 eployment of ViAggre and show that ViAggre can also yield faster route con
 vergence.\n\nBio:\nHitesh Ballani has recently joined Microsoft Research C
 ambridge as a Researcher. He received a Ph.D. from Cornell University in 2
 009 and a B.Tech degree from IIT Roorkee\, India in 2003. His research int
 erests are in networked systems with his work striking a balance between c
 lean-slate and dirty-slate proposals. Past projects include research in ne
 twork management\, routing\, security and network architecture.\n
