“…Finally, because the LROA aims to support a large number of users over a common physical medium, further issues relevant to security improvement and reliability in the optical access systems, which might not have been addressed previously, would be of great importance. In this context, several schemes were proposed in the literature to increase the level of survivability in FTTH networks (Ab-Rahman et al, 2011;Ab-Rahman et al, 2012) …”

The ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, creates the motivation to upgrade the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to NextGeneration Optical Access Networks (NG-OANs). Beside the need for more bandwidth per user, a further extension in the range and an increase in the split ratio are highly desirable in PONs. These additional requirements can be achieved by adopting so-called Long-Reach Optical Access Networks (LR-OANs). LR-OANs offer a promising solution that ensures a significant number of users can be supported over a longer range. Moreover, they introduce a cost-effective approach in which both the access and metro segments of the telecommunication network are combined into one backhaul segment, which results in the consolidation of many central offices into one trunk-exchange. This cost-effective approach gave us the motivation to provide a comprehensive survey on the LR-OANs. In this study, we first provide a brief review of different potential technologies, proposed for next-generation optical access. We then provide a review of different stat-of-the-art LR-OAN architectures including opportunities and challenges in each one. A comparison among them based on key network specification is also provided.

Due to the increasing amount of data traveling computer networks every day, efficient management of this information is required to ensure the quality of the services provided by them. Development of new network management tools and mechanisms is a widely approached area due to its importance, not only to the current technology, but also to next generation network standards and equipments. Several researches have been directed to the use of IP Flows in order to increase the efficiency of these management tools. Although there are several proposed approaches in this area, most of them don't have suitable test scenarios to validate their performance results. In this study, we present Scorpius, a new simulation tool able to help testing network management mechanisms based on IP Flows. Scorpius is capable of simulating different kinds of anomalies, such as Denial of Service (DoS), Distributed Denial of Service (DDoS), Flash Crowd and Port Scan, directly into the flow export files. This characteristic unites the advantages of tests in real network environments without the drawbacks of the occurrence of real anomalies and attacks, even controlled ones. This approach makes the processes of performance analysis of anomaly detection approaches easier, without interfering or hampering the operation of the analyzed network. In order to validate the efficiency of the presented tool, we use real data collected from a large-scale network environment.
