Modeling energy management mechanism in ethernet passive optical networks

Abstract: A new aspect in the design of future network is the energy efficiency. An energy management mechanism is proposed and evaluated for the Ethernet Passive Optical Network (EPON). With regard to power saving, a sleep mode operation is developed at the Optical Network Unit (ONU). Therefore, power is conserved by switch off some operating functions. The sleep period and wakeup period are computed and assigned using two alternative scheduling schemes. Simulation results show a significant power saving. Furthermore, performance study illustrates a tradeoff between energy efficiency and network performances, such as queuing delay and network bandwidth utilization.

Architecting Self-Tuning Optical Networks

Abstract: We describe an IP-optical traffic management system that creates a "self-tuning" optical core. We show that an adaptive transport layer can significantly improve network efficiencies and thus, reduce capital and operating expenses for the carrier.

Toward deeply virtualized elastic optical networks

Abstract: We discuss the virtualization in optical networks from the elastic networking level to sliceable equipment level. We propose a novel transport system architecture based on equipment level virtualization that achieves fine granular sub-port level grooming in the optical domain.

Resilient backhaul network design using hybrid radio/free-space optical technology

Abstract: The radio-frequency (RF) technology is a scalable solution for the backhaul planning. However, its performance is limited in terms of data rate and latency. Free Space Optical (FSO) backhaul, on the other hand, offers a higher data rate but is sensitive to weather conditions. To combine the advantages of RF and FSO backhauls, this paper proposes a cost-efficient backhaul network using the hybrid RF/FSO technology. To ensure a resilient backhaul, the paper imposes a given degree of redundancy by connecting each node through K link-disjoint paths so as to cope with potential link failures. Hence, the network planning problem considered in this paper is the one of minimizing the total deployment cost by choosing the appropriate link type, i.e., either hybrid RF/FSO or optical fiber (OF), between each couple of base-stations while guaranteeing K link-disjoint connections, a data rate target, and a reliability threshold. The paper solves the problem using graph theory techniques. It reformulates the problem as a maximum weight clique problem in the planning graph, under a specified realistic assumption about the cost of OF and hybrid RF/FSO links. Simulation results show the cost of the different planning and suggest that the proposed heuristic solution has a close-to-optimal performance for a significant gain in computation complexity.
