Action Overview

The primary objective of COST291 is to focus on novel network concepts and architectures exploiting the features and properties of photonic technologies, to enable future telecommunications networks. It is aiming to propose a new generation of systems and networks that will accommodate the unpredictable and growing size of data files and messages exchanged and stored as well as real time services (e.g. voice, video etc) over global distances requiring an agile Communication Grid supporting quality services. These need to provide end-to-end bandwidth for transmission of traffic for applications such as information retrieval, downloading (often multimedia) web software, exchange of various type of software (hundreds of Mbytes) and data models (Gbytes) etc as well as real time multimedia applications.

Working groups

• WG1: “Optical processing for digital network performance”.
  This workgroup will focus on physical layer and implementation related issues of transparent optical networks and will cover advanced topics such as optical signal per bit processing, optical switch architecture designs and implementations as well as transmission related issues.
• WG2: “Novel network architectures”.
  This workgroup will focus on the evolution of network scenarios including the study of novel network architectures. This workgroup will also study different node architectures and technologies in terms of network performance and functionality. Three different architectures will be studied and compared: circuit (wavelength, waveband etc), optical burst and optical packet switched networks.
• WG3: “Unified control plane, network resilience and service security”.
  This workgroup will focus on two directions. The former will deal with the impact of transparency on photonic network architectures and the associated control and protocol issues. The latter will focus on network survivability and security issues, covering topics such as protection and restoration, its impact on routing and wavelength assignment algorithms, fault isolation, disaster recovery, etc.
