The current trend is to integrate a constantly increasing number of services in the same
communication network. Some services have very high resilience requirements, while other …

In this article traffic-engineering issues regarding network survivability, traffic grooming,
impairment-aware routing, virtual-topology engineering, and coordination among multiple …

This letter introduces a matrix-based approach to connection unavailability estimation in
shared backup path protection (SBPP). The proposed approach yields accurate results for …

In optical networks, shared-backup path protection (SBPP) can optimize network resources
utilization in scenarios where connection resilience requirements are not achieved without …

We propose two versions of Link Failure Probability (LFP) based backup resource sharing
algorithms, namely LFP based First-Fit algorithm, and LFP based Best-Fit algorithm for …

This paper investigates what impact optical node failures may have on wavelength-division-
multiplexed networks, in which reliable end-to-end optical circuits are provisioned …

This paper presents a simple way to determine routing and wavelength assignment for
connection demands subject to reliability constraints using SPP schemes. The solution is …

Feature Issue on Next-Generation WDM Network Design and Routing (WDMN) The optimal
choice of routing and wavelength assignment (RWA) for the working and protection path …

The paper studies the impact of OXC equipment failure in WDM networks with dynamic end-
to-end optical circuit provisioning. At the OXC level, equipment reliability is calculated using …

Wavelength division multiplexed (WDM) technology has revolutionized wide-area networks.
As the amount of traffic carried is very large, any single failure can be catastrophic. Thus …
