This volume contains the proceedings of the NOC 2001 at Adastral park, UK, June 26-29 2001. With about 70 papers, this book highlights the gigabit ethernet PON developments, and other work on standard broadband PONs such as, dynamic bandwith assignment. There are 10 papers on optical packet switiching and work on optical cross-connects and DWDM for long-haul systems is presented.
Volume 1 "WDM and Photonic Networks" will focus on recent developments in long-haul WDM and photonic networks and will include invited papers from key vendors and technologists. A paper on DWDM by Lucent will show how Raman amplification enables the quadrupling of the line rate from OC-192 to OC-768 in a recent 1.6Tb/s experiment.
Volume 2 "Broadband Access, WDM Metro and Network Management" shows how new optical technologies and architectures can improve the performance of broadband access and WDM metropolitan networks. WDM passive optical networks and WDM rings feature strongly in this volume. A paper from a group of key vendors in Germany will describe a DWDM metro ring network with up to 800 Gb/s using novel add-drop multiplexers.
New broadband services, which depend upon state-of-the-art technology, will drive investment in broadband access networks for both business and residential applications such as switched video and fast internet access. Unlike core networks where fibre is ubiquitous, the way to broadband access in the future could come from a number of alternative technologies: fibre, hybrid fibre-coax, hybrid fibre-radio, and hybrid fibre-metallic pair systems. De-regulation has created new market opportunites in Europe, which will drive investment in broadband access. Papers published in these proceedings give insight into these and other key issues facing network designers: comparing alternative technologies as investment opportunities; investigating new system designs - APON, HFR and HFC; examining the role of WDM in access; and introducing new techniques for fast file transfer.
The demand for ever more capacity over the lucrative long-haul routes coupled with the need for higher reliability is pushing optical technology towards its limits. WDM systems allow upgrading of existing core networks and offer new opportunities for long-haul systems design towards ultimate terrabit systems. The prospect of an all-optical layer offers new possibilties for dynamic management of capacity and protection switching. Papers published in these proceedings: explore business opportunities for WDM systems; highlight recent advances in key technologies such as add drop multiplexers, arrayed planar waveguides and broadband EDFAs; present new bandwidth management techniques; and push the transmission limits to the technology by minimizing dispersion, non-linearities and intermodulation effects, and charts the way to soliton systems.
This volume explores the impact of emerging broadband technology on the design of full services access networks. As new technologies such as fibre-optics, ATM transport, and broadband access and interfacing are introduced into telecommnunications networks, the opportunity arises to introduce new network and service management techniques. Benefits of this include reduced cost of ownership, increased customer satisfaciton, and low prices for new services. This volume explores the use of standardized protocols and modelling techniques, TMN-based management applciations, distributed computing environments, object-oriented technology, and legacy systems integration, with particular application to the systems covered by other themes of NOC'98.
Multi-media networks based on fibre core networks and ATM technology will provide the broadband communications platform for both business and entertainment services with integrated transmission of voice, data and visual information direct to the work-station or set-top point. The demand for Internet is driving capacity needs rapidly towards WDM. This work discusses issues concerning end-to-end performance such as reliablility, capacity, delay, efficiency, signalling, management and cost - all of which need to be resolved and agreed if ATM is to become the ubiquitous service platform.
New broadband services, which depend on state-of-the art technology, are expected to drive investment in broadband fibre optic networks. Rapid growth in fibre optic systems is likely to lead to the development of a fibre superhighway. This study explores the impact of emerging broadband services and technology on fibre systems design and deployment of the superhighway. Multi-media networks based on ATM LAN technology can provide integrated transmission of voice, data and visual information direct to the workstation. The strategic importance of such networks to organizations which depend on electronic transmissions, and the smooth operation of these networks is therefore of critical importance. This text investigates the state of corporate networks, and provides a view of how emerging new technology will improve communications efficiency. It also aims to show how the cost of the technology and its installation can be reduced to a level which is affordable to users, in order to gain maximum benefit from new services on a reliable network.
Broadband services, which depend on state-of-the-art technology, are expected to drive investment in broadband fibre optic networks. A fibre superhighway is confidently predicted within the next 10 years. This text explores the impact of emerging broadband services and technology on fibre systems design and deployment of the superhighway.
Multi-media networks based on ATM LAN technology can provide integrated transmission of voice, data and visual information direct to the workstation. Such networks are of strategic inportance to organiztions which depend on electronic transactions. The smooth operation of these networks is therefore of critical importance. This study investigates the state of corporate networks, and provides a view of how emerging technology will improve communications efficiency.
Although almost unlimited capacity is available on fibre, the technology is only acceptable for transmission if it also meets cost and reliability requirements. Fibre has already proved itself in submarine and core network applications. The aim of this study is to show how the cost of the technology and its installation can be reduced to a level which is affordable to users in order to gain maximum benefit from new services on a reliable network.
