Network Planning Tools
Support tools: Business
• Required functionality for Business tools
- Service Demand Projection
- Dynamic modeling for technology substitution and migration rates
- Dimensioning multiple flows (circuit and packet modes)
- Evaluation of network resources and associated investment
(CAPEX)
- Evaluation of revenues for given tariffs and installation rate
- Modeling multiple resource lifetimes
- Modeling of demand elasticity to tariffs
- Interrelation between network growth and operational cost (OPEX)
- Cost assignment as a function of utilization rates
- Generation of standard financial results like Cash Flow, Profit &
Loss, Balance Sheet, NPV, IRR, etc.

Support tools: Design and Optimization (I)
• Required functionality for Technical design tools
– Service demands characterization and traffics for VoIP and NGN
multiservice flows
– Conceptual Network Design and Capacity Planning
– Comparison of different network structures
– Routing flows for most typical cases including OSPF, shortest path,
widest path and weighted cost functions.
– Optimizing locations and connections of network gateways
– Cost, Performance and Reliability Analysis
– Estimation of investment costs for the rollout and the extension of the
investigated multi-service network
