SUMMARY:EndRE: An End-System Redundancy Elimination Service for Enterprise
  Traffic - Ram Ramjee (MSR India)

DESCRIPTION:In many enterprises today\, middleboxes called WAN optimizers 
 are deployed across WAN access links in order to eliminate redundancy in n
 etwork traffic and reduce WAN access costs.  However\, middleboxes do not 
 cope well with end-to-end  encrypted traffic and do not improve performanc
 e of mobile smartphones operating over wireless links. In this talk\, we p
 resent the design and implementation of EndRE\, an end system-based redund
 ancy elimination service. Since the service relies on opportunistically le
 veraging resources on end hosts\,  EndRE is designed to be adaptive\, asym
 metric and parsimonious in resource usage. Based on the enterprise traffic
  traces\, testbed experiments and a pilot deployment\, we show that EndRE 
 delivers ~30% bandwidth savings\, processes payloads at speeds of 1.5-4Gbp
 s\, and translates bandwidth savings into equivalent energy savings on mob
 ile smartphones.\n\nBio:\nRam Ramjee received his B.Tech in Computer Scien
 ce from IIT Madras in 1992\, and his M.S./Ph.D. in Computer Science from U
 niversity of Massachusetts\, Amherst in 1994 and 1997\, respectively. He i
 s currently a Senior Researcher at Microsoft Research\, India. Previously\
 , he spent ten years at Bell Labs\, NJ as a technical manager and a distin
 guished member of technical staff. His research interests include network 
 protocols and architecture\, wireless networking and mobile computing. He 
 has taught two graduate-level courses in wireless networks as an adjunct f
 aculty at Columbia University. He has served as the Technical Program Co-C
 hair of IEEE ICNP'04 and ACM MobiCom'06. He has published over 50 papers\,
  holds 16 patents and is a Fellow of the IEEE.\n
