Routing, Spectrum, and Transponder Assignment (RSTA) in Elastic Optical Networks
Backbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable transponders (SBVTs) that support the simultaneous generation of multiple optical carriers. Such carriers can be used to serve different lightpaths (i.e., slice-ability), o...
متن کاملRouting and Spectrum Assignment for Constant Bit Rate Connections in Spectrum Sliced Elastic Optical Path Networks
In this paper a heuristic algorithm for finding an optical path in elastic optical path networks is proposed. The proposed algorithm for connection requests finds a spectrum required from an aggregated spectrum of the path belonging to a set of shortest paths measured by the number of links. It has been shown that the proposed algorithm rejects definitely fewer connection requests than the well...
متن کاملRouting and Spectrum Assignment in Spectrum Flexible Transparent Optical Networks
. The considered problem of routing and spectrum assignment (RSA) takes into consideration minimizing the length of the transmission distance under spectrum continuity constraints and the relationship between the traffic bitrates and the spectrum bandwidth. The proposed algorithms constitute modifications of the well-known Dijkstra's algorithm. The obtained results show that a significant reduc...
متن کاملImpairments-aware Routing and Spectrum Allocation in Translucent Flexgrid Networks
Devising a highly flexible and efficient optical transport network with various requirements and features is a main challenge in network design and the connection requests within the network are performed by the Routing and Spectrum Assignment (RSA) algorithms. These algorithms compute the route and allocate the demanded spectrum to the connection in request, where each demanded spectrum is ava...
متن کاملScheduling-Inspired Spectrum Assignment Algorithms for Mesh Elastic Optical Networks
Spectrum assignment has emerged as the key design and control problem in elastic optical networks. We have shown that spectrum assignment in networks of general topology is a special case of scheduling multiprocessor tasks on dedicated processors. Based on this insight, we develop and evaluate efficient and effective algorithms for mesh and chain networks that build upon list scheduling concepts.
