Performance of elastic optical network with limited slicers

ICT Express, 2023
A bandwidth blocking occurs due to bandwidth fragmentation in an elastic optical network, which arises from setting up and tearing down of lightpaths. An appropriate routing and spectrum allocation (RSA) approach can reduce this blocking.
