Resource Savings in Submarine Networks Using Agility of Filterless Architectures

Agile filterless optical networking

“…Based on the cost and spectrum consumption results, we can conclude that filterless networks can be considered as a valuable network technology in metropolitan and aggregation networks. Elastic filterless case: results at 16 Tb/s of traffic [6,10,13,14].…”

“…Finally, a dynamic network resource allocation scheme and algorithm have been proposed to leverage the agility of a filterless multi-span submarine network experiencing daily non-synchronous traffic variations between nodal pairs. The results show that filterless networks can enable significant transceiver and spectrum savings in long haul networks with time-varying traffic load [15].…”

“…Similar studies carried out on submarine networks have shown that the filterless technology can reduce the terminal cost by 30-44% and the line equipment cost by 11-12% when compared to conventional submarine networks where ROADMs can be deployed only at the cable landing stations [12][13][14][15].…”

“…Wavelength or spectrum consumption in filterless networks has been studied extensively [6][7][8][9][10][12][13][14]. Typical performance results are illustrated in Fig.…”

Programmable Filterless Optical Networks: Architecture, Design, and Resource Allocation

“…An in-depth study of the RMSA problem in FONs was carried out in [3] by developing an ILP formulation and a heuristic approach based on genetic algorithm (GA). Dynamic connection provisioning in FONs was addressed in [16] for terrestrial networks, while [17] investigated the resource savings benefits of dynamic connection reconfiguration under periodic traffic in filterless submarine networks. A control plane design based on path computation element (PCE) was proposed in [18].…”
