From the proposal submitted to DOE (April, 2001). section 3.6.2 ORNL Timeline in Milestones Year 1. 1. Deploy Web100 at ORNL and NERSC nodes to develop Net100 expertise 2. Develop and demonstrate Web100-aware data transfer application for Probe/HPSS testing between NERSC and ORNL 3. Contribute to test and evaluation of existing end-to-end tools 4. Get access to ESnet ORNL and NERSC routers and investigate possible realtime feedback to application (e.g. using SNMP) 5. Explore transport optimizations for single TCP flows 6. Develop file transfer application/protocol to support out-of-order packet arrivals 7. Deploy a small emulator testbed to test transport protocol modifications and out-of-order resilient protocols/applications 8. Explore tuning the IBM/AIX 5.1 TCP stack and investigate extending it with Net100 mods 9. Test net100 tools on ESnet's OC48 testbed 10. Publish tools and tips on web page and in formal publications and presentations Year 2. 1. Integrate Net100 tools into HPSS transfer protocols 2. Modify kernels to support ECN and use Net100 tools to tune DOE TCP applications with ECN feedback (assumes DOE's ESnet routers will be ECN-capable) 3. Continue Net100 integration with other vendor TCP stacks (Solaris, Irix, Compaq) 4. Integrate ORNL's network-daemon statistical sampling research with NWS/Net100 5. Extend Net100 tools to include adaptive source-based routing and multipath routing via application daemons Year 3. 1. Continue Net100 integration with other vendor TCP stacks (Irix, FreeBSD) 2. Extend Net100 tuning to include DOE's IPv6 network (jumbograms)
