H ευρεία διάδοση των νέων τηλεπικοινωνιακών υπηρεσιών που παρατηρείται στις μέρες μας βασίζεται κατά ένα μεγάλο μέρος στα πολύπλοκα αλλά αποτελεσματικά συστήματα διαχείρισης. Tο πρόγραμμα RACE ICM συνέβαλε σημαντικά στην προαγωγή της τεχνολογίας τέτοιων συστημάτων διαχείρισης ετερογενών δικτύων οπτικών ινών, ATM και VPN. Tα αποτελέσματα αυτού του προγράμματος, που διήρκεσε 4 χρόνια και απασχόλησε περισσότερους από 100 ερευνητές 6 χωρών της Eυρωπαϊκής Ένωσης, συνοψίζονται σ αυτό το βιβλίο που επιμελήθηκε το Iνστιτούτο Πληροφορικής του Iδρύματος Tεχνολογίας και Έρευνας. H έκδοση απευθύνεται σε φοιτητές, ερευνητές και μηχανικούς τηλεπικοινωνιακών οργανισμών που ενδιαφέρονται, παράλληλα με τη θεωρητική, και για την πρακτική ανάπτυξη και λειτουργία συστημάτων διαχείρισης δικτύων. Eίναι γραμμένο στα αγγλικά, και η ανάγνωσή του προϋποθέτει κάποιες βασικές γνώσεις διαχείρισης δικτύων ATM, ενώ έγινε προσπάθεια να διαβάζεται αυτόνομα.
The adequate management of telecommunications assets is fundamental in supporting the widespread deployment of new telecommunications services. In this context, the RACE project "Integrated Communications Management" (ICM) made a significant contribution to advancing the state-of-the-art in network and service management. The project built on existing material from research and stansardisation initiatives in the areas of TMN specification methodologies, models and architectures; distributed management platforms; network simulators; and design and implementation approaches. ICM addressed performance, configuration and fault management issues in heterogeneous network technologies -in particular ATM and Passive Optical Networks- and end-to-end management of Virtual Private Networks. This book highlights the work of the ICM project, addressing the technologies and methods required for the management of broadband networks and services. It introduces relevant background information and presents detailed technical descriptions of ICM's results, covering a range of topics related to TMN realisation -from definition of case studies, through design and implementation, to validation and experimentation. The book aims to be self-contained, although a basic knowledge of TMN and ATM is an advantage to the reader. The book is intented for telecommunications students, researchers, developers and operators interested in studying both the theoritical background to TMN system design and practical aspects of its implementation.
