    ABSTRACT: A Colorless and Directionless (C&D) ROADM architecture has empowered today's networks with the much needed flexibility and scalability to handle the unpredictable high bandwidth demands, provide any-to-any connectivity and provision new services without disrupting the existing ones. In this paper, we realize the C&D ROADM architectures using PXC and WSS at a multi-degree node. We then evaluate both the architectures based on the various advantages offered by them. We also discuss some of the drawbacks of the two architectures. Subsequently, we propose a Colorless, Directionless and Contentionless (CD&C) architecture which combines the features offered by both the C&D architectures. Finally, we discuss practical implementation issues of the proposed architecture.

    ABSTRACT: Service Providers are constantly searching for means to reduce costs, generate new revenue streams and thus increase their competitive advantage. The migration to a Colorless and Directionless mesh architecture will enable the Service Providers to realise scalable, flexible and dynamically reconfigurable optical networks. But commodification and standardization of the underlying technologies has made it very difficult to differentiate their service offerings especially in terms of price and performance. Hence, leveraging the intelligence of efficient routing algorithms, Service Providers can notably reduce the total cost of ownership of the network. This paper presents a rationalized routing algorithm for a Colorless and Directionless mesh core optical network, which enables a significant CAPEX reduction by decreasing the number of active degrees of a node.
