Meeting the requirements to deploy cloud RAN over optical networks
Luis Velasco,Andrea Castro,A. Asensio,Marc Ruiz,Gengchen Liu,Chuan Qin,Roberto Proietti,S. J. B. Yoo +7 more
TL;DR: The connectivity requirements of C-RAN applications are studied and it is concluded that dynamicity, fine granularity, and elasticity are needed, and an SBVT architecture based on dynamic optical arbitrary generation/measurement is proposed and assessed.

Designing an efficient clustering strategy for combined Fog-to-Cloud scenarios
A. Asensio,Xavier Masip-Bruin,Ramón J. Durán,I. de Miguel,Guang-Jie Ren,S. Daijavad,Admela Jukan +6 more
TL;DR: A machine learning-based heuristic that provides scalable and near-optimal solutions in realistic scenarios in which, due to the high number of connected devices, solving the MILP formulation is not viable is proposed.

TL;DR: This paper presents the C-RAN Capital Expenditures (CAPEX) minimization problem to decide which COs should be equipped and the equipment to be installed, and results showed remarkable costs savings when a lower level of centralization is considered.

Impact of aggregation level on the performance of dynamic lightpath adaptation under time-varying traffic
A. Asensio,Miroslaw Klinkowski,Marc Ruiz,Victor Lopez,Alberto Castro,Luis Velasco,Jaume Comellas +6 more

TL;DR: Up to 21% more traffic is served with the proposed elastic SA than with the fixed SA in a network with low aggregation and high lightpath capacity, as simulation results show.
Dynamic virtual network connectivity services to support C-RAN backhauling
TL;DR: In this paper, the authors propose dynamic customer virtual network (CVN) reconfiguration to be supported in metro and core network segments, and exhaustive simulation results study its performance in realistic scenarios.
