ABSTRACT
Abstract
Traffic grooming in optical networks has gained significance due to the prevailing sub-wavelength requirement of end users. The networks on the other hand get upgraded to the latest technology, however slowly with time. The networks are thus comprised of nodes employing heterogeneous switching architectures. In this talk, a framework for connection establishment in a wavelength division multiplexed (WDM) grooming network with heterogeneous switching architectures will be discussed. The information that could be collected from the links and various operators that could be used to obtain information on a path are illustrated with examples. This information can be used to select a path dynamically depending on the network status. The framework is completed by providing a generic channel assignment procedure that could be employed to implement different channel assignment schemes. The proposed framework can be implemented in networks that collect network information through link-state protocol and employ source-based routing. For large networks, a set of candidates paths can be probed and a path could be selected.
