The Advanced Computing Systems Association (USENIX) selected a paper written by an HP Labs team as "best student paper" at its annual technical conference this month.
The paper, "EtE: Passive End-to-End Internet Service Performance Monitoring," describes a new technique for measuring performance characteristics of Internet services.
The paper's authors are: Yun Fu, a Duke University PhD student who is now a second-year intern at HP Labs; HP Labs researchers Lucy Cherkasova and Wenting Tang and Amin Vahdat, a professor in Duke's computer science department.
EtE monitor introduces a novel approach for measuring Web site performance. It passively collects network packet traces at the server site to determine service performance characteristics. EtE monitor is based on a two-pass heuristic method and a statistical filtering mechanism to accurately reconstruct composition of individual pages and to measure performance characteristics integrated across all client accesses.
E+E monitor has several advantages over existing approaches:
- a breakdown between the network and server latency for retrieving a Web page
- longitudinal information for all client accesses, not just the subset probed by a third party
- characteristics of accesses that are aborted by clients
- quantification of the benefits of network and browser caches on server performance.
An extended version of the paper is now available as an HP Labs technical report.
Also at USENIX: John Wilkes of HP Labs and Theodore Wong of Carnegie Mellon University presented their paper, "My Cache or Yours? Making Storage More Exclusive." Mirjana Spasojevic of HP Labs was a member of the USENIX program committee.
