Performance analysis of elastic optical networks (EONs) switches under unicast traffic

Iran Journal of Computer Science, 2019
Bandwidth variable-wavelength cross connect switches (BV-WXCs) play an important role in the routing and spectrum assignment (RSA) problem in elastic optical networks (EONs). These switches, whose structure has been derived from micro electro mechanical systems technology, aim to switch the incoming traffic flexibly such that the existing resources are

Best fit (BF): A new Spectrum Allocation mechanism in Elastic Optical Networks (EONs)

2016 8th International Symposium on Telecommunications (IST), 2016
Routing and spectrum allocation (RSA) is known as a key challenge in elastic optical networks (EON). Specifically, RSA process is categorized as (i) without adjusting modulation format (simply referred to as RSA), and (ii) with adjusting modulation format (referred as routing, modulation level and spectrum allocation (RMSA)).
