  1. WheelFS Jeremy Stribling, Frans Kaashoek, Jinyang Li, Robert Morris MIT CSAIL and New York University

  2. I Want to Publish an SOSP Paper • But I don’t want to do a lot of work • Idea: New cooperative Web cache!

  3. Exploit a Network File System Apache Caching Proxy Apache Caching Proxy Apache Caching Proxy Apache Caching Proxy foo.html Network File Server (/mnt/awesome-cdn/cache)

  4. It Is Too Good to Be True • Tries to mask failures with long timeouts • Strict consistency prevents use of cached data under failures • My naïve SOSP strategy might not work

  5. So What Are My Options? • Give up dream and just not graduate • Submit random paper [Rooter, WMSCI ’05] • Build an FS that would work for real apps • Apache can use old copies of data • And can always fall back to the origin • Why not tell the FS?

  6. WheelFS: Storage for Wide-area Apps • File system API • Semantic cues give apps control of behavior under failures •  Make Apache distributed with 1 line change

  7. Cooperative Web Cache on WheelFS Apache Caching Proxy Apache Caching Proxy Apache Caching Proxy Apache Caching Proxy WheelFS WheelFS WheelFS WheelFS /wfs/cache/ .maxtime=500 /.bestversion /.lax /$URL Use newest version you can find quickly Time out operations after T milliseconds Allow multiple versions of a directory to be updated

  8. I’m Running Out of Time, So: • A compact but powerful set of cues • Useful to other applications, including: • PlanetLab measurement studies • Parallel Grid computations • Distribute make • See you at the next big conference!
