“…As a consequence of the growing importance of anycasting in the context of cloud computing, new static and dynamic optimization problems appear in order to provide high reliability for the networks. Some initial works have been conducted in this field, e.g., [41,117,145].…”

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

“…Results of the experiments reveal that the joint dual homing performs considerably better than individual dual homing that attacks NodeB level and RNC level separately and independently. In [21], the authors address the problem of network survivability in the context of anycast communications. To assure the network survivability, they use the single backup path approach.…”

Overlay multicasting providing live streaming services became crucial service in contemporary Internet. In this paper, we focus on applying the overlay multicasting for delivering of critical data that require to be transmitted safely, intact and with as little delay as possible. To improve survivability of the overlay multicasting, we propose to use dual homing approach, i.e., each peer is connected to the overlay by two separate access links. We consider the following network failures: overlay link failure, uploading node failure and ISP interconnection failure. The main goal of our experiments is to determine the additional cost of providing survivability to the overlay multicasting network with dual homing technology for both flow assignment and capacity and flow assignment problems. Our studies indicate that the additional survivability requirements do not have a substantial impact on the overlay multicasting system expressed as streaming cost or network cost.

“…At the core, analytics monitor transfer rates, cache hit ratios, and bandwidth for simultaneous unicast connections [6]. Often these reports are provided on an hourly basis, so that a content owner can track simultaneous viewers, progress of large-file delivery, and status of network cache utilization.…”
