From strategy to implementation - Tool based planning of optical networks

This paper presents a comprehensive tool based planning process of optical networks to solve the problems from strategy to implementation, especially for brown-field planning with network merge, migration or convergence. Referring to cross layer design, this planning strategy is proposed for fixed and mobile convergence from IP networks to transports networks. The importance of a tool support is verified for strategic planning, detailed design and implementation. In addition, two case studies from previous projects are discussed to identify the planning issues and the efficiency of this approach.
