“…Finding the best parameters configuration, such as bandwidth allocation, routing, and modulation allocation, considering the specific characteristics of flexible grid DWDM networks was proposed in [50]. The global bandwidth scheduling heuristic algo-rithm for complex IP over OTN networks using computational intelligence was proposed in [67] and was explored to ensure efficient bandwidth allocation. Heuristic algorithms seeking to optimize the allocation of resources, such as wavelengths, routes, and bandwidth, considering network constraints and requirements, were addressed in [44], [45], [34].…”

This paper presents a systematic review applying the PRISMA methodology with a Systematic Review Protocol (SRP) on the definitions of methods, techniques, and algorithms used for optical transport network (OTN) planning. OTN has been extensively used worldwide, and many issues still need to be studied. We conducted a comprehensive review of the relevant studies to provide insight into the recent progress and the research gaps in the field. According to the analyzed studies, research questions and open issues are associated with using Machine learning, Resilience, and Energy Consumption. These approaches are highlighted as future research directions to enable the development of OTN planning.

AbstractAn important problem of network traffic is how to efficiently carry massive amounts of data traffic generated by Peer-to-Peer (P2P) services in high-speed and large-capacity optical access networks. P2P file-sharing traffic is regarded as one of the biggest bandwidth consumption in the world. Internet service providers can reduce the bandwidth burden in the feeder fiber by localizing the network traffic. In this paper, we propose an enhanced redirection strategy based on the optimized MPCP protocol (ERS-MPCP) to redirect the traffic into the access network and reduce the latency. A Markov chain is used for mathematical modeling. In the proposed strategy, we build a simulation platform for network simulation. Simulation results show that our strategy can improve the overall redirection success rate by up to 9%, thereby reducing the data traffic burden on the core network.

In the development of ethernet passive optical networks (EPONs), quality of service (QoS) support and fairness per optical network unit (ONU) are crucial issues. However, making an elaborate analysis of the existing prediction-based bandwidth allocation algorithm, light load penalty, low prediction precision are pointed out. We present an improved dynamic bandwidth pre-allocation algorithm (R-DBA), which employs recurrent neural network (RNN) to predict the high-priority service traffic in EPON. And we introduce mixed integer linear programming (MILP) for optimally building DBA algorithm. This algorithm achieves the prediction of the high-priority service traffic by RNN during the waiting time and supports bandwidth pre-allocation, thus ensuring the fairness of the bandwidth allocation.
