Technical Report – D 41 - 2 Design of study case solutions & Study cases evaluations

This document, which is an update of the previous D41 deliverable, describes problems, approaches and solutions in the area of network management, from the TIGER2 point of view. Besides solution design, it provides detailed evaluations of the proposals showing the feasibility of self-* paradigms when addressing network control and management issues. Higher manageability issues are tackled in six areas. 1) The hitless maintenance approach eases the work of the human operator by mastering maintenance tasks through automated processes. 2) The approach for energy aware routing exploits ideas of flow aggregation, and aims at finding the optimal type and amount of resources for balanced network performance and power efficiency. 3) OPEX and CAPEX awareness through a new networking architecture is described through the LOCARN concept of TIGER2. 4) Further self-optimized network resource allocation can be achieved by fine-tuning the characteristics of the Spanning Tree Protocol. 5) Inter-domain traffic engineering problems are proposed to be tackled through sharing the intelligence between control planes. 6) Finally, more knowledge could also be gathered through extensive traffic monitoring, which allows traffic mix and traffic matrix analysis (among others) to support decision making in order to actuate proper modifications at the network node level for optimal operation.
