Journal ArticleDOI
Duopoly Competition in Time-Dependent Pricing for Improving Revenue of Network Service Providers
TL;DR: Analytical and experimental results show that the TDP benefits the NSPs, but the revenue improvement is limited due to the competition effect, and a duopoly NSP case is studied.
Journal ArticleDOI
Joint Progressive Network and Datacenter Recovery After Large-Scale Disasters
Sifat Ferdousi,Massimo Tornatore,Ferhat Dikbiyik,Charles U. Martel,Sugang Xu,Yusuke Hirota,Yoshinari Awaji,Biswanath Mukherjee +7 more
TL;DR: This work solves the optimization problem of joint progressive recovery to find the optimal sequence of network element and DC repairs with the objective to maximize cumulative weighted content reachability in the network, and proposes a scalable heuristic for scheduling the sequential repair of network nodes/links and DCs.
Signaling Extensions for Wavelength Switched Optical Networks
TL;DR: This document provides mechanisms to support distributed wavelengths assignment with a choice of distributed wavelength assignment algorithms.
Journal ArticleDOI
A Two-Stage Simulated Annealing Logical Topology Reconfiguration in IP over WDM Networks
TL;DR: A simulated annealing approach is proposed to determine the target topology with a smaller logical topology change and satisfy the performance requirement and a threshold on the congestion performance requirement is used to balance the optimal congestion requirement and operation complexity.
Journal ArticleDOI
Emergency OPM Recreation and Telemetry for Disaster Recovery in Optical Networks
Sugang Xu,Yusuke Hirota,Masaki Shiraiwa,Massimo Tornatore,Sifat Ferdousi,Yoshinari Awaji,Naoya Wada,Biswanath Mukherjee +7 more
TL;DR: This work proposes an approach for quick recreation of OPM and for achieving robust telemetry based on OpenConfig YANG that can tolerate low post-disaster bandwidth and can adapt the telemetry system following the changing conditions of the C/M-plane network.
