Measurements
Performance statistics
- Impact of traffic demands on the network
- delay, loss, throughput from active probes between edge systems
- Utilization, loss statistics from passive monitoring of links, nodes
- Mapping of statistics onto the network topology
Traffic Demands
- An accurate view of the demands themselves is extremely useful for effective traffic engineering
- A large fraction of the traffic is interdomain, and a large number of customers are multihomed
- Model traffic demands as loads from an edge interface to a set of candidate edge interfaces
