Evaluation Methodology

• Develop QoS enabled version of OSPF

• Benchmark key operations from implementation

  • Computation of QoS routing table
  • Processing of LSA
  • Access to topology database
  • Path selection (pre-computation)

• Combine benchmarking and simulation to emulate operation in “large” network

  • Simulation trace logs events at router
  • Router load is “computed” based on trace and stand-alone costs
