Multi-Layer Network Design: A Model-Based Optimization Approach
Source: Zuse Institute Berlin
This paper presents a model-based optimization approach for the design of multi-layer networks. The proposed framework is based on a series of increasingly abstract models - from a general technical system model to a problem specific mathematical model - which are used in a planning cycle to optimize the multi-layer networks. In a case study one shows how central design questions for an IP-over-WDMnetwork architecture can be answered using this approach. Based on reference networks from the German research project EIBONE, the paper investigates the influence of various planning parameters on the total design cost. This includes a comparison of point-to-point vs. transparent optical layer architectures, different traffic distributions, and the use of PoS vs. Ethernet interfaces.
