5- Capacity planning
- Simultaneously choosing a topology, link capacity, and routing metrics for a new network
- Or, which link capacity to enhance in an existing network
- Usually a matter of trial and error
- Some steps
- measure busy hour traffic
- create traffic matrix
- decide topology
- assign capacity
- choose routing weights
- Routing and link capacity interact
- What to measure for building traffic matrix?
- How to pick routing weights?
- Heterogeneity?
