“…On the other hand, the protection granularity becomes finer [17]: (i) the protection selectivity [18] between unprotected and protected traffic can be made on a per-channel basis in Variant 2 and 3 while it is on a per-fiber basis (thus, multiple channels) in Variant 1, (ii) a single channel failure (e.g., failure of channel termination equipment such as lasers) can affect protection switching of (still operating) other channels in Variant 1 and 2.…”

Abstractp-Cycle recovery relies on a protection switching protocol. We detail several issues for such a protocol taking the evolution from ring networks to p-cycles into account. In particular, we propose and evaluate a protocol enhancement to provide means for node failure protection. For the evaluation, we describe an integer linear program, which is applied to network design case studies, and formulate availability models for p-cycles. The case studies show that the protocol enhancement improves availability at marginal additional design cost.

“…Likewise, links between these LSRs may be implemented by virtual or physical connections of an underlying SONET/SDH or optical layer. Multilayer networks provide rerouting or protection switching capabilities and backup capacity on different layers [9]. This seems to be a waste of resources, but protection on lower layers reacts faster than rerouting on the IP layer.…”

Abstract. In this work we optimize administrative link costs of IP networks in such a way that the maximum utilization of all links is as low as possible for a set of considered failure scenarios (e.g., all single link failures). To that aim, we present the new "hill hopping" heuristic with three different variants and compare their computation times and the quality of their results. We adapt the objective function of the heuristic to make the link cost settings robust to single link failures, single node failures, and single link or node failures, and compare the results. In particular, we optimize the routing for multilayer networks where unused backup capacity of the link layer can be reused to redirect traffic on the network layer in case of an IP node failure.

“…However, in this case, it is important to define proper rules of cooperation between network layers to provide the multilayer resilience. This is a well-researched area, and the respective interworking strategies defining e.g., the sequence of network layers to perform recovery of affected flows, as well as a way of exchanging the respective information between the network layers, have been proposed e.g., in [32,38,39].…”

In this position paper on reliable networks, we discuss new trends in the design of reliable communication systems. We focus on a wide range of research directions including protection against software failures as well as failures of communication systems equipment. In particular, we outline future research trends in software failure mitigation, reliability of wireless communications, robust optimization and network design, multilevel and multirealm network resilience, multiple criteria routing approaches in multilayer networks, resilience options of the fixed IP backbone network in the interplay with the optical layer survivability, reliability of cloud computing networks, and
