On the Upgrade of an Optical Code Division PON with a Code-Sense Ethernet MAC Protocol

Abstract: We propose, for the first time, optical code-sense multiple access / collision detection to upgrade an optical code division passive optical network with minor modifications to transparently deploy Ethernet (or packet) based services.

Pioneering hardware modeling and software design for optical infrastructure in the Autonomous Network project

Abstract: Experimental platforms are essential to demonstrate the potential benefits that Software Defined Networking (SDN) can bring to optical metro and backbone carriers' infrastructure. In this context, the Autonomous Network (AN) project is an SDN-enabled five-node metropolitan optical network test-bed located at CPqD. The AN main objective is to bring novel SDN concepts and capabilities down to the physical/optical layer for performance improvements in different dimensions. In this paper, we first present a comprehensive description of the AN infrastructure comprising the pioneering modeling of hardware equipment and software design in the SDN controller. Then, we review recent research activities, which include SDN-enabled adaptive and cognitive algorithms to improve end-to-end performance, and experimental demonstrations in the optical layer. Finally, we comment on different SDN designs and white-box networking to enable further equipment programmability in future optical networks.

Development of optical backbone railway infrastructure

Abstract: The optical backbone networks are already well developed at telecom world. Public Railways companies are still in phase of defining and development of its telecommunication and signalization backbone network. This paper will describe problematic points of the development, integration and future extension of optical backbone networks. Also it will consider advantages and disadvantages of certain technologies and its usability for the future usage and extensions. It will cover not only the design the network for railways needs but it will also cover the ability to compete on open wholesale market.

Dimensioning hybrid PONs

Abstract: We investigate FTTX (Fiber-to-the Home/Premises/Curb) Passive Optical Networks (PON) for the deployment of broadband access networks such that the opportunities of optical fiber enabled technologies as well as of passive switching equipment can be exploited We focus on designing the best possible architectures of hybrid FTTX PONs, which embraces both TDM and WDM technology Advantages of hybrid PONs are twofold: they can (i) offer increased data rate to each user by employing WDM technology, (ii) provide flexible bandwidth utilization by employing TDM technology We propose a novel network design optimization scheme for greenfield deployment of a set of hybrid PONs For a given geographical location of an optical line terminal (OLT), a set of optical network units (ONUs) and their corresponding aggregated traffic demand, our proposed optimization scheme determines the design and dimensioning of the most economical set of hybrid PON networks while satisfying unicast/multicast traffic demands and taking into account the signal attenuation constraints Computational experiments have been conducted on a set of up to 512 ONUs in order to evaluate the performance of the proposed scheme

Scheduling algorithm for differentiated service on wavelength-division-multiplexed passive optical access networks

Abstract: Passive optical networks (PONs) will be the pervasive choice in the design of next-generation access networks. One possible solution to implementing passive optical access networks is to rely on wavelength-division multiplexing (WDM). Here we investigate the problem of providing real-time service to both hard and soft real-time messages in conjunction with a conventional best-effort service in WDM optical networks based on the single-hop passive-star coupler. We propose an adaptive scheduling algorithm to schedule and manage the message transmissions in the specified network. We have conducted extensive discrete event simulations to evaluate the performance of the proposed algorithm.
