Topological optimization of reliable networks under dependent failures

J Barrera, H Cancela, E Moreno - Operations Research Letters, 2015 - Elsevier
We address the design problem of a reliable network. Previous work assumes that link
failures are independent. We discuss the impact of dropping this assumption. We show that …

Interval availability estimation for protected connections in optical networks

DAA Mello, H Waldman, GS Quitério - Computer Networks, 2011 - Elsevier
Routing and wavelength assignment under availability constraints has been extensively
researched recently. Availability (or more precisely, steady-state availability) can be defined …

Network resilience in future optical networks

L Wosinska, D Colle, P Demeester, K Katrinis… - Towards Digital Optical …, 2009 - Springer
Network resilience is an issue of deep concern to network operators being eager to deploy
high-capacity fibre networks, since a single failure in the network could result in significant …

Adaptive schemes for differentiated availability-aware connection provisioning in optical transport networks

B Kantarci, HT Mouftah, SF Oktug - Journal of lightwave technology, 2009 - opg.optica.org
In this paper, we present two adaptive schemes, namely, global differentiated availability-
aware provisioning (G-DAP) and link-by-link differentiated availability-aware provisioning …

Fast simulation of service availability in mesh networks with dynamic path restoration

AE Conway - IEEE/ACM Transactions on Networking, 2010 - ieeexplore.ieee.org
A fast simulation technique based on importance sampling is developed for the analysis of
path service availability in mesh networks with dynamic path restoration. The method …

Analytical bounds on the unavailability of protected connections in WDM optical networks

QoT-and SLA-aware survivable resource allocation in translucent optical networks

J Zhao, S Subramaniam - 2015 IEEE Global Communications …, 2015 - ieeexplore.ieee.org
Survivability is a critical issue in high-capacity wavelength division multiplexing based
optical networks, since even a disruption for a very short time could result in the loss of a …

Trading availability among shared-protected dynamic connections in WDM networks

D Lucerna, M Tornatore, B Mukherjee, A Pattavina - Computer Networks, 2012 - Elsevier
Novel automatized management systems for optical WDM networks promise to allow
customers asking for a connection (ie, a bandwidth service) to specify on-demand the terms …

Availability‐driven optimal design of shared path protection in WDM networks

M Tarifeño‐Gajardo, A Beghelli, E Moreno - Networks, 2016 - Wiley Online Library
Availability, defined as the fraction of time a network service is operative, is a key network
service parameter. Dedicated protection increases availability but also the cost. Shared …

Design and analysis of partial protection mechanisms in groomed optical WDM mesh networks

M Sivakumar, J Fang, KM Sivalingam… - Journal of Optical …, 2008 - opg.optica.org
We consider the problem of survivable network design in traffic-groomed optical WDM mesh
networks that support subwavelength capacity connections. In typical survivable network …
