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 …

To provide fast traffic recovery upon failures, most modern networks support static Fast
Rerouting (FRR) mechanisms for mission critical services. However, configuring FRR …

To evaluate the expected availability of a backbone network service, the administrator
should consider all possible failure scenarios under the specific service availability model …

This paper focuses on how to increase the availability of a backbone network with minimal
cost. In particular, the new framework focuses on resilience against natural disasters and is …

To meet the stringent requirements on the maximally tolerable disruptions of traffic under link
failures, many communication networks feature some sort of static failover mechanism for …

Mobile edge computing allows efficient cloud servicing by building small-scale cloud
infrastructures at the network edge close to end users. The cloud servers implement virtual …

Common daily activities rely on information exchange and processing. Optical fiber links are
the predominant way for transmitting vast amounts of data, thus enabling processing in …

Guaranteeing a high availability of network services is a crucial part of network
management. In this study, we show how to compute the availability of network services …

In this paper we present a novel framework for disaster resilience, called FRADIR, which
incorporates reliable network design, disaster failure modeling and protection routing in …

In Software-Defined Networking (SDN) links and switches (nodes) from data plane suffer
from failure and impact network operations. In the presence of such failures, switches can …
