Influence of the spatial super channel guard-band width on the performance of dynamic Flex-Grid/SDM optical Core networks

Capacity Quantification of Joint-switching-enabled Flex-Grid/SDM Optical Backbone Networks

“…In order to quantify the capacity scalability in Flex-Grid/SDM networks, we consider two topologies: 1) the Deutsche Telekom 12-node network (DT12), with an average link length of 243 km; and 2) the United States 26-node network (US26), with an average link length of 469 km [4,8]. In each network link we scale the spatial multiplicity |S| from 7 to 30, which correspond to the best single-mode MCF prototypes found in the literature [2,3].…”

“…The higher | | used, the lower the resulting bit-rate per Sb-Ch and the higher the possibility to allocate lower spectral resources (frequency slots −FSs−). The Sb-Ch content can be generated/detected by sub-wavelength multiplexing in the electrical domain [8]. The number of electrical subcarriers depends on its line-rate which can be set at lower value in order to reduce the impact of ASE noise.…”

Solving the Static Resource-Allocation Problem in SDM-EONs via a Node-Type ILP Model

“…Resource-allocation problems in optical networks, such as RWA in WSON, RSA in EONs, and RSSA in SDM-EONs, can be divided into static (e.g., [5,) and dynamic scenarios (e.g., [21,[30][31][32][33][34][35]). In static scenarios, all connection requests are known in advance, and the objectives are usually to determine the network design required to accommodate all known connection requests or to minimize the amount of resources required for various sets of known connection requests.…”
