Abstract

The routing and wavelength assignment algorithm is a complex task in today's dynamically switched networks. As the number of network nodes and links increases, advertising link states requires more control messages, larger databases and more processing capacity while searching for an available path. Information aggregation in multi-domain networks helps us to reduce the number of advertised links. Furthermore, there are numerous information update strategies that also result in less link state control messages. However, these enhancements are done on the account of information inaccuracy, which leads to higher blocking ratio and longer setup delays. In our article we present a Physical Device Abstraction Layer for the Control Plane where interior optical switches having different multiplexing capabilities and exterior autonomous domains are treated in a unified way. Next we show and analyse solutions for how to apply information update strategies on multilayer networks and how to extend these strategies to fit info multi-domain environment.
