Abstract

The energy consumption of transport networks gets more and more attention as it is expected to become a problem with future traffic increase. Dynamic optical bypassing is a promising approach to tackle increasing energy consumption as well as growing resource usage. Performance evaluations are necessary in order to find suitable bypassing approaches. Recently, distributed approaches for bypass establishment and teardown have been proposed. There is so far no comprehensive performance evaluation available. In this paper, we present four different distributed heuristics for bypassing. We implemented a simulation framework for the performance evaluation of these heuristics. Two approaches without dynamic bypassing serve as reference. The results show benefits of dynamic bypassing with respect to required energy and resources. We relate these benefits to the necessary switching operations.
