EtE: Passive End-to-End Internet Service Performance
Yun Fu, Duke University; Ludmila Cherkasova, Wenting Tang, Hewlett-Packard Laboratories; Amin Vahdat, Duke University
This paper presents, EtE monitor, a novel
approach to measuring web site performance. Our system passively
collects packet traces from a server site to determine service
performance characteristics. We introduce a two-pass heuristic method
and a statistical filtering mechanism to accurately reconstruct
different client page accesses and to measure performance
characteristics integrated across all client accesses. Relative to
existing approaches, EtE monitor offers the following benefits: i) a
breakdown between the network and server overhead of retrieving a web
page, ii) longitudinal information for all client accesses, not just
the subset probed by a third party, iii) characteristics of accesses
that are aborted by clients, and iv) quantification of the benefits of
network and browser caches on server performance. Our initial
implementation and performance analysis across two sample sites
confirm the utility of our approach.
