Towards an effective energy efficient passive optical network

Abstract: Communication networks' energy consumption poses a considerable threat to the environment stability. The expansion of access networks, which constitute the main playground of the Internet backhaul, is accompanied by numerous energy inefficient devices and equipments. Passive optical networks (PONs) is a potential dominant technology on the field of access networking, hence the reduction of the consumed energy of the optical devices forms a critical issue. In this paper, an efficient green PON is introduced, having two main targets: a) to reduce the energy consumption, by allowing optical devices to operate longer in sleep mode, and b) to maintain PON's good performance. Beyond the green provisioning, the proposed scheme is able to increase occasionally the network performance in terms of mean packet delay and packet drop ratio. This is accomplished by reducing the amount of control messages between subscribers, operating in sleep mode, and central office, allowing more bandwidth to be allocated for data delivering.

On the reduction of ONU upstream buffering for PON/xDSL hybrid access networks

Abstract: We investigate upstream transmission coordination for PON/xDSL hybrid access networks. We introduce a novel GATED flow control mechanism to reduce the upstream buffering at the optical network unit (drop point) that bridges the fiber and copper transmission media. We provide extensive experimental analysis of various flow control mechanisms including our novel GATED flow control.

Resource management in an integrated optical network

Abstract: We propose a novel integrated optical network switching architecture. The proposal offers an approach to signaling for the purpose of transport on an all-optical network of optical and nonoptical legacy network traffic. In order to provide effective end-to-end control and efficient transport services, new signaling and control techniques are required. Standard organizations such as Optical Interworking Forum (OIF) and Internet Engineering Task Force have developed interface methods between client and transport networks, as well as signaling processes for resource allocation. We propose a network controller, which implements interfaces for such integration in the intermediate future, as well as provides a feasible path for the long-term objective of all optical networking. Performance and capacity issues for these systems introduce new dimensions to the existing set of networking problems, since optical paths can now be set up in real-time. There are two main contributions in this paper: (1) functional composition of a network controller, which translates legacy signaling to optical connection signaling and path establishment and (2) determining when to issue an optical connection request based on the current network conditions such as link utilization, so that the integrated optical network can operate efficiently. Analytical approximations, as well as simulation results for call blocking performance are also presented.

Multi-Layer Switching in Packet Optical Transport Systems

Abstract: Packet optical transport systems (POTSs) combine latest generation connection- oriented Ethernet with optical transmission and switching. This presentation explores the requirements for multi-degree switching at all layers in the POTSs transport stack.
