Overview
Das Ziel dieses Projekts ist die Entwicklung von Netzwerkarchitekturen und Systemlösungen für die Nutzung in zukünftigen Breitband Zugangsnetzwerken. Die Anstrengungen konzentrieren sich auf transparente ringförmige Austauschnetze auf der Basis von multi-wavelength photonischen Switches mit dem Ziel, die Netzwerkfunktion und -kapazität zu erhöhen.
Das vorgeschlagene Szenario bezieht sich auf sehr leistungsfähige Netzwerke mit transparenten Verbindungen zwischen den 'Core/regional-metro' Ringen, die Datenraten von bis zu 160 GBit/s und den 'Metro-access' Ringen, die Datenraten von bis zu 40 GBit/s unterstützen. Dies wird durch optisch schaltende Knoten, die an den Austauschpunkten zwischen den Ringen sitzen, bewerkstelligt.
Das Design orientiert sich an kostengünstigen Lösungen, die dennoch transparent die Verbindung zwischen den verschiedenen Bereichen herstellen. Diese Lösung wird zusätzliche Funktionen erfüllen können, die bisher auf der optischen Ebene noch nicht realisiert wurden. V.a. die Aggregation von Daten und die 2R optische Regenerationen auf vielen Wellenlängen wird dazugehören. Die Vielzahl von Datenraten, Protokollen und Formaten die heutzutage in Metro- und Accessnetzwerken üblich sind, wird durch die Transparenz des o.g. Ansatzes unterstützt und ihn dadurch auch für zukünftige Anwendungen vorbereiten.

Introduction
TRIUMPH
(Transparent Ring Interconnection Using Multi-wavelength PHotonic switches)
Main Objectives
"To develop the network technologies and architectures allowing a generalised and affordable availability of broadband access to European users, including those in less developed regions, peripheral and rural areas" (IST "Broadband for all" Strategic Objective).
This project proposes the development of network architectures and system solutions that will facilitate future broadband access networks. The effort will focus on Transparent Ring Interconnection using multi-wavelength photonic switches with the aim to increase the network functionality and capacity. The proposed scenario refers to a high capacity networks with transparent connectivity between core/regional-metro rings supporting data rates up to 130Gbit/s and metro-access rings supporting up to 40Gbit/s. The required functionality in such architecture will be provided through an optical switching node located at the interconnection points between rings. The design and development of this node will be the focus of the project with the aim to provide a cost effective solution that can transparently offer inter-domain connectivity. This solution will also support functionalities currently unavailable in the optical layer. Our approach will offer transparent optical grooming/aggregation and multi-wavelength 2R optical regeneration. This transparency will enable a variety of data rates, protocols and formats that are present in the metro and access network environments and are associated with the requirements of new and emerging services and applications that are rapidly becoming available to the end-users.
Key Issues
Due to the unpredictable growth of data, particularly internet traffic, the emergence of higher-bandwidth applications originating from the users and the requirements for content delivery the future communication grid must be agile and able to react rapidly to support end-to-end bandwidth requirements. Related to this there is an incredible amount of pressure placed on metropolitan area networks as the metro network segment imposes limitations in the delivery of broadband services to the end-users.
- A new generation of metro networks is required to relieve this pressure and to offer the means to enable the metropolitan network to allow for quality end-to-end connectivity and value-added services.
- Technical breakthroughs in research are required to further accelerate the realization of transparent optical networks to offer increased transmission bandwidth, integrated transmission and switching capabilities and optical signal processing functionality.
- Transparent networks will be based on advanced photonic infrastructures that will employ optical signal processing and dynamic impairment management to eliminate the limitations of the analogue nature of optical networks. In addition new enhanced features need to be supported.
Expected Impact
The innovations introduced by the project aim at establishing a breakthrough in the implementation and deployment of advanced optical communications across an interdisciplinary array of both industrial and research stakeholders. It is expected to bring a significant impact in a number of areas including: network architectures, system implementation and technologies suitable for future broadband networks: access, metro-access and core-metro. More specifically it will:
- Provide improvement of the signal quality and the overall network performance through optical multi-wavelength 2R regeneration, thus enabling the transparency requirements.
- Provide all optical grooming/aggregation, i.e. conversion of lower rate WDM signals into higher rate single channel OTDM streams and vice versa, further enhancing the transparent functionality of the proposed system, offering an additional feature required in metro and access network environments.
- Offer reduced power consumption and compact size
