Flexgrid technology is now considered to be a promising solution for future high-speed network design. In this context, we need a tutorial that covers the key aspects of elastic optical networks. This tutorial paper starts with a brief introduction of the elastic optical network and its unique characteristics. The paper then moves to the architecture of the elastic optical network and its operation principle. To complete the discussion of network architecture, this paper focuses on the different node architectures, and compares their performance in terms of scalability and flexibility. Thereafter, this paper reviews and classifies routing and spectrum allocation (RSA) approaches including their pros and cons. Furthermore, various aspects, namely -fragmentation, modulation, quality-of-transmission, traffic grooming, survivability, energy saving, and networking cost related to RSA, are presented. Finally, the paper explores the experimental demonstrations that have tested the functionality of the elastic optical network, and follows that with the research challenges and open issues posed by flexible networks.Index Terms-Elastic optical networks, node architecture, spectrum management, routing and spectrum allocation, and sliceable bandwidth-variable transponder.

“…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. So far, in the literature there have been proposed relatively few works addressing the survivability of EON, e.g., [45,84].…”

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

“…However, in order to reduce the utilization of resources, backup resources can be shared between the demands whose primary paths do not fail at the same time (contrary to DPP, for which each demand has its own backup resources). For more details on DPP and SBPP problems in EONs, refer to [48] and [49].…”

Failures in optical networks are inevitable. They may occur during work being done for the maintenance of other infrastructures, or on a larger scale as the result of an attack or large-scale disaster. As a result, service availability, an important aspect of Quality of Service (QoS), is often degraded. Appropriate fault recovery techniques are thus crucial to meet the requirements set by the Service Level Agreements (SLAs) between the carriers and their customers.In this paper, we focus on practical issues related to the deployment of fault recovery mechanisms in commercial optical networks. In particular, we outline the most important functionalities that, to our knowledge, need to be implemented, as well as discuss the related problems making deployment of fault recovery mechanisms difficult. Investigated topics include: fault recovery challenges (fault detection, location, and recovery), multiple failures recovery, as well as application of reliability mechanisms in elastic optical networks, and in multiprovider multilevel networks.
