Fragmentation-aware routing and spectrum allocation algorithm in mixed-grid optical networks
Opto-Electronics and Communications Conference, 2023The flex-grid technology is recognized as a promising solution to improve flexibility and scalability in optical networks. A gradual migrating process from the conventional fixed-grid to flex-grid networks is considered as a practical upgrading strategy,

On routing and spectrum allocation in spectrum-sliced optical networks
2013 Proceedings IEEE INFOCOM, 2013The orthogonal frequency division multiplexing (OFDM) technology provides an opportunity for efficient resource utilization in optical networks. It allows allocation of multiple sub-carriers to meet traffic demands of varying size. Utilizing OFDM technology, a spectrum efficient and scalable optical transport network called SLICE was proposed recently.

Routing and spectrum allocation in SLICE optical networks
2016 International Conference on Electrical, Electronics, Communication, Computer and Optimization Techniques (ICEECCOT), 2016The SLICE architecture for a 6-node network with its components is analyzed. Balanced load spectrum allocation and shortest path with maximum reuse are simulated to address the routing and spectrum allocation. The algorithms results show the reduction in sub-carrier utilization in a SLICE optical network.

Routing and Spectrum Allocation in Spectrum-Sliced Elastic Optical Path Networks
2011 IEEE International Conference on Communications (ICC), 2011Recently, the OFDM-based Spectrum-sliced Elastic Optical Path (SLICE) network attracts significant interests due to its elastic band-width allocation. The OFDM technology, on one hand, enables both sub-wavelength and super-wavelength traffic accommodation by allocating appropriate number of sub-carriers.

Routing and Spectrum Allocation
2016To properly analyze, design, plan, and operate flex-grid networks, the routing and spectrum allocation (RSA) problem must be considered. The RSA problem involves two basic constraints: the continuity constraint to ensure that the allocated spectral resources are the same along the links in the route, and the contiguity constraint to guarantee that ...
