  1. Tapestry on PlanetLab Deployment Experiences and Applications Ben Zhao, Ling Huang, Anthony Joseph, John Kubiatowicz

  2. Our Experience • Tapestry on PlanetLab • Deployed Java implementation on 67 nodes • Large scale routing and location measurements • 6-7 node instances per physical node • A wish list • Uniformity in network configuration • Isolation (bounded scheduling latencies) • Dynamically updated pair-wise distance map • Transparent file synchronization ravenben@eecs.berkeley.edu

  3. Our Goals • A persistent Tapestry on PlanetLab • Application platform with extensible P2P routing • Persistent on selection of distributed PlanetLab nodes • Global backbone for larger Tapestry • Dynamic integration via introduction service • Incremental upgrades via ordered node restarts • Practical utility services available to PL users • Application / service control via IM (Shuttle) • Quick and dirty file sharing (Interweave) • Distributed file system (OceanStore) ravenben@eecs.berkeley.edu

  4. Snapshot Measurements • Real Tapestry network of 400+ nodes • Measured routing and location RDP under load • Scheduling / contention artificially increases RDP • Routing RDP median: 2.5  1 • Location RDP median: 5  1 ravenben@eecs.berkeley.edu

  5. Infrastructure Services • Simple but useful utility applications • Shuttle: decentralized chat service • Persistent state replicated across network • Decentralized message routing via Tapestry • Graphical UI, w/ AIM-like functionality • command mode can be used as a wall / zephyr – like tool • Interweave: deterministic file sharing • Simple file sharing via object location • Metadata replicas distributed across network • Search (match) on primary fields, pruning via secondary fields • Locates nearby object replicas ravenben@eecs.berkeley.edu
