For several decades, optical networks, due to their high capacity and long-distance
transmission range, have been used as the major communication technology to serve …

An inherent problem in Software-Defined Networking (SDN) is the Controller Placement
Problem, which addresses how many controllers to deploy in the network, and where to …

The communication network is the critical infrastructure and backbone of modern society. On
the other hand, regional failures, including natural disasters and malicious attacks, pose a …

As an effective way to defend against network failure, nodes or links in a network can be
protected to ensure connectivity. The consolidation of critical nodes is a necessary strategy …

The paper addresses a bicriteria optimisation problem in telecommunication networks that
aims at finding Pareto efficient pairs of paths between two given nodes, seeking to minimise …

As one realistic way to improve the robustness of network, the protection of critical links will
help build resilient link structure to defend against random link failure, especially in sparse …

Random failure is a common threat to a network, where the failure of a few edges can
disconnect a large-scale sparse network. To enhance the robustness of network, the …

Disjoint path routing approaches can be used to cope with multiple failure scenarios. This
can be achieved using a set of k (k> 2) link-(or node-) disjoint path pairs (in single-cost and …

In this paper, we revisit a biobjective optimization problem arising in software-defined
networking with availability guarantees. The problem jointly optimizes the number of …

To build robust networks, a popular way is to add edges to existing networks, which can help
defend against natural disasters or malicious attacks that randomly or intentionally break …
