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.

    ABSTRACT: In this paper, we propose a novel bandwidth-flexible reconfigurable optical add/drop multiplexer (ROADM) architecture based on coherent optical-orthogonal frequency division multiplexing (CO-OFDM) technology. The bandwidth-flexible ROADM architecture enables sub-wavelength, superwavelength, and multiple-rate data traffic accommodation in a highly spectrum-efficient manner, thereby providing a fractional bandwidth service. We simulate and compare the blocking performance of bandwidth-flexible ROADM with and without wavelength converters. It is found that wavelength converter could obviously improve the blocking performance of bandwidth-flexible ROADM with different frequency grid. Moreover, the conversion ratios are calculated for different load and channel spacing. Based on the analysis of conversion ratio, we could make an appropriate configuration of wavelength converters in bandwidth-flexible ROADM.

    ABSTRACT: Elastic optical networks are envisaged as promising solutions to fulfill the diverse bandwidth re-quirements for the emerging heterogeneous network applications. To support flexible allocation of spectrum re-sources the optical network nodes need to be agile. Among the different proposed solutions for elastic nodes, the one based on architecture of demand (AoD) exhibits consider-able flexibility against the other alternatives. The node modules in the case of AoD are not hard-wired, but can be connected/disconnected to any input/output port accord-ing to the requirements. Thus, each AoD node and the net-work (fabricated with AoD nodes) as a whole acts like an optical field-programmable gate array. This flexibility in-herent in AoD can be exploited for different purposes, such as for cost-efficient and energy-efficient design of the networks. This study looks into the cost-efficient network planning issue for synthetic networks implemented through AoD nodes. The problem is formalized as an inte-ger linear programming formulation for presenting the optimal solution. Furthermore, a scalable and effective heuristic algorithm is proposed for cost-efficient design, and its performance is compared with the optimal solution. The designed networks with AoD nodes are further inves-tigated for a dynamic scenario, and their blocking probabil-ity due to limited switching resources in the nodes is examined. To alleviate the blocking performance for the dy-namic case, an efficient synthesis strategy along with a scheme for optimal placement of switching resources within the network nodes is presented. Extensive results show that 1) even at high loads, the network with AoD nodes achieves saving of switching modules up to 40% com-pared to the one with static reconfigurable optical add– drop multiplexers (ROADMs) through a proper network design, 2) by diminishing the spectrum selective switches the overall power consumption of the network decreases by more than 25% for high loads, and 3) for the dynamic sce-nario the blocking owing to the node modules constraint is alleviated significantly by slightly augmenting the switch-ing devices and optimally deploying them within the network nodes.
