Abstract
|
We study an access trace containing a sample of Wikipedia's
traffic over a 107-day period aiming to identify appropriate
replication and distribution strategies in a fully decentralized
hosting environment. We perform a global analysis of the whole
trace, and a detailed analysis of the requests directed to the
English edition of Wikipedia. In our study, we classify client
requests and examine aspects such as the number of read and save
operations, signicant load variations and requests for
nonexisting pages. We also review proposed decentralized wiki
architectures and discuss how they would handle Wikipedia's
workload. We conclude that decentralized architectures must
focus on applying techniques to efficiently handle read
operations while maintaining consistency and dealing with
typical issues on decentralized systems such as churn,
unbalanced loads and malicious participating nodes.
