“…However, unlike, say, in wireless LANs or xDSL systems where OFDM is deployed as a transmission technology in a single link, in optical networks it is being considered as the technology underlying the novel elastic network paradigm [6]. Consequently, in the quest for a truly agile, resource-efficient optical infrastructure, networkwide spectrum management arises as a key challenge and the routing and spectrum assignment (RSA) problem has emerged as an essential network design and control problem [13], [14].…”

Abstract-Spectrum assignment has emerged as the key design and control problem in elastic optical networks. We have shown that spectrum assignment in networks of general topology is a special case of scheduling multiprocessor tasks on dedicated processors. Based on this insight, we develop and evaluate efficient and effective algorithms for mesh and chain networks that build upon list scheduling concepts.

In the paper we present integer programming (IP) optimization models for flexgrid elastic optical networks (EON). We consider several different basic assumptions regarding flexibility of EON that lead to a variety of IP formulations differing in precision and complexity. As usual, detailed models aiming at precisely describing technological aspects of EON suffer from tractability issues resulting from their greater complexity and have to be reasonably simplified. To achieve this, we consider cases where the bandwidth is divided into predefined slots, cases where the bandwidth is continuous and can be divided between demands with no restrictions, cases where a list of predefined paths is available, and finally cases where all the paths are indirectly taken into account. We present both compact and non-compact formulations. The non-compact formulations are accompanied with brief description of the dedicated column generation algorithms.

“…Thus, there is a growing need for an introduction of an efficient and scalable transport platform for links of 100 Gb/s and beyond. A recent proposal to answer this challenge is the idea of EON that utilizes the spectrum resources more efficiently compared to DWDM and provides more flexibility [75,83]. Since the operation of EON differs significantly from the currently used optical technologies, many new aspects and problems including survivability and optimization must be considered by the research community in the context of EON.…”

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
