Title: PLANet: An Active Network Testbed


1
PLANet An Active Network Testbed
  • Michael Hicks and Jonathan T.Moore
  • Presented by Moonjoo Kim

2
Overview of PLANet
  • Network based on PLAN system
  • Implementation detail
  • OCaml in user space
  • Linux 2.0.30 kernel
  • 300 MHz Pentium II with 256 MB mem
  • 100 Mbps Ethernet

3
PLANet performance
  • Latency measurement
  • For IP, ICMP based ping
  • For PLANet
  • one which evaluates on the dest and source
  • one which evaluates on every hop
  • Bandwidth measurement

4
Three experiments with active internetworking
  • Adaptation to traffic condition on a path
  • Compress its payload for making fewer fragments
  • Modification of a queueing strategy
  • Use fair queue rather than FCFS
  • Selection of a better route
  • "Shop around" for a route with the best bandwidth
