With the frequent occurrences of natural disasters damaging large portions of
communication networks and the rising risk of intentional attacks, network vulnerability to …

This article investigates complexity and approximability properties of combinatorial
optimization problems yielded by the notion of Shared Risk Resource Group (SRRG). SRRG …

With the wide deployment of network facilities and the increasing requirement of network
reliability, the disruptive event like natural disaster, power outage or malicious attack has …

Abstract Network Function Virtualization (NFV) is an enabling technology to handle today's
wide variety of services and to match the traffic demands to the available network resources …

We propose and analyze a graph model to study the connectivity of interdependent
networks. Two interdependent networks of arbitrary topologies are modeled as two graphs …

With the growing need for a robust network backbone to ensure uninterrupted connectivity in
the face of large-scale natural disasters, we introduce the Risk Zone-Diversified Network …

We study the diverse routing problem in WDM optical networks with SRLG failures. We
consider a more general case of SRLG failures than those considered in Datta and Somani …

Failure resilience is a desired feature in communication networks, and different methods can
be considered in order to achieve this feature. One of these methods is diverse Routing. In …

We consider the problem of survivability in multilayer networks. In single-layer networks, a
pair of disjoint paths can be used to provide protection for a source-destination pair …

Regional failures, such as natural disaster or malicious attack, have become a major threat
to the construction of future reliable communication network. The regional failures usually …
