Description, Development and Analysis of Network Structures

Objectives:
• Extend existing frameworks for evaluation, comparison and benchmarking of net-work structures. Main focus on parameters, which are useful for real world network planning, and more sophisticated models for reliability.
• Describe properties of known and new network structures according to the frame-works developed.
• Develop better reference models for regular structures.
• Test and develop routing, restoration and protection schemes for network struc-tures.
• Develop methods for combining and connecting different network structures. Hier-archical extensions for good structures should be developed, preserving good struc-tural properties and support for algorithms.
• Develop extensions of schemes for routing, restoration and protection, which can be used for wavelength routing in fibre networks.
Methods:
• Graph theoretic tools, methods and concepts.
• Simulations and calculations.
• Further development of the test and demonstrator network
