Operational Costs
Simulation used to generate trace of router activity
- Requests with exponential duration (avg. 3 min) and Poisson arrivals (avg. about 1 req/sec)
- Non-uniform traffic patterns
- Request size uniformly distributed in [0-1] Mbit/sec
Drive router with trace or compute router load based on trace and stand-alone costs
Evaluation of router load
- “Instantaneous” utilization (over 50 msec intervals)
- Average utilization (over the simulation duration)
