The explosive growth of data, particularly internet traffic, has led to a dramatic increase in demand for transmission bandwidth imposing an immediate requirement for broadband networks. The primary objective of the COST 291 Action "Towards Digital Optical Networks" was to focus on novel network concepts, subsystems and architectures to enable future telecommunication networks, exploiting the features and properties of photonic technologies.

Three working groups were established to deal with these research objectives:

WG1 "Optical processing for digital network performance," dealt with the physical layer and implementation related issues of transparent optical networks such as optical signal per bit processing, optical switch architecture designs and implementations as well as transmission related issues.

WG2 "Novel network architectures," focused on the evolution of network scenarios including novel network architectures. Also different node architectures and technologies in terms of network performance and functionality were investigated. Three different architectures were studied and compared: circuit (wavelength, waveband, etc.), optical burst and optical packet switched networks.

WG3 "Unified control plane, network resilience and service security," dealt as well with the impact of transparency on photonic network architectures and the associated control and protocol issues as 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.

The results obtained within these working groups are collected in this volume.

This book constitutes the refereed proceedings of the 11th International IFIP-TC6 Conference on Optical Network Design and Modeling, ONDM 2007, held in Athens, Greece, in May 2007.

The 41 revised full papers presented together with 14 invited papers were carefully reviewed and selected from over 90 submissions. The papers address all recent advances in the design, modeling and implementation of optical networks, including novel switching schemes and paradigms, network optimization and design, new concepts for link and control layer protocols, advanced network subsystems and node architectures, and network inter-working schemes.

This book constitutes the thoroughly refereed post-conference proceedings of the Third International ICST Conference on Networks for Grid Applications, GridNets 2009, held in Athens, Greece, in September 2009.

The 10 full papers, 3 invited papers and 2 invited keynotes address the whole spectrum of Grid networks and cover various topics such as authorisation infrastructure for on-demand Grid and network resource provisioning, access control requirements for Grid and cloud computing systems, business models, accounting and billing concepts in Grid-aware networks, multiple resource scheduling in e-science applications, percolation-based replica discovery in peer-to-peer grid infrastructures, GridFTP GUI, alarms service for monitoring multi-domain Grid networks, Grid computing to explore the computational resources of the settop boxes, open source cloud computing systems based on large scale high performance, dynamic network services, WDM ring networks, architecture to integrate broadband access networks and wireless Grids, implementation of random linear network coding using NVIDIA's CUDA toolkit, collaboration in a wireless Grid innovation testbed by virtual consortium as well as challenges for social control in wireless mobile Grids
