Telecommunication networks are a critical infrastructure of our society. Wide area backbone
communication networks are based on optical networks, where each fiber has a very large …

Feature Issue on High Availability in Optical Networks The core idea of availability-based
routing consists of exploiting the availability as a link-state metric: this kind of approach has …

In this paper we provide a centralized method for optimally selecting the set of active and
backup paths in an optical transport network in the cases of shared-path restoration and 1: 1 …

As telecommunication networks are a critical infrastructure of our society, they must evolve to
provide high end-to-end availability and high resilience to large-scale disasters. Path …

This paper addresses two related problems in the context of transparent optical networks. In
the network design problem, the aim is to identify a set of fiber links to connect a given set of …

This work presents the problem of survivable path pair routing in multi-domain optical
networks with geographically correlated failures. The objective is to minimize the risk of …

In this paper, we investigate the problem of survivable all-optical routing in WDM networks
with physical impairments. One of the recent key issues in survivable optical network design …

Data explosion and higher service level agreements (SLA) are common terminologies in
modern communication networks. Recent advancements toward 5G networks add to the …

Network survivability endeavors to ensure the uninterrupted provisioning of services by the
network operators in case of a disaster event. Studies and news reports show that network …

Disaster events directly affect the physical topology of core networks and may lead to
simultaneous failure of multiple lightpaths leading to massive service outages for network …
