Abstract

Continuously increasing traffic volumes raise hardware requirements of core networks considerably. Dynamic network operation combined with the use of flexrate transponders promises a viable potential for improved efficiency in core network operation. In this paper, we analyze the additional topological flexibility offered by flexrate transponders based on a simple model which is then used in a dynamic network reconfiguration approach adapting the network periodically according to the given traffic demands. We evaluate the resulting resource efficiency in terms of required line cards and latency by event-driven simulations. Results show that the gains in topological flexibility in the presented approach do not offer any additional advantage and that the approach can incur increased transmission latencies which can be avoided by an extension at a cost in terms of reduced efficiency gains.
