Every nation wants to achieve Universal Access of telecommunication services due to its importance to the economy and national life. Unfortunately in sub-Saharan Africa, telecommunication services are either scarce or non-existent in rural areas. However, previous telecommunication policies have enabled the provision of various network technologies in Africa. What type of policy is needed to pu...

Hosts (or nodes) in the Internet often face epidemic risks such as virus and worms attack. Despite the awareness of these risks and the availability of anti-virus software, investment in security protection is still scare, hence, epidemic risk is still prevalent. Deciding whether to invest in security protection is an inter-dependent process: security investment decision made by one node can af...

Telecommunication networks are extremely complex systems requiring high reliability and availability. The effective management of these networks is a critical, but complex, task. To help with this problem, the telecommunications industry has heavily invested in intelligent technologies. This chapter describes intelligent technologies and applications used within the telecommunications industry....

Many efforts have been made to manage homogenous B-ISDN networks across multiple domains. However, less effort has been made for hybrid BISDN network management. The ACTS MISA(Management of Integrated SDH and ATM networks) project addresses the issue of hybrid ATM and SDH management, aiming to automate the end-to-end GBC (Global Broadband Connectivity) service in the integrated ATM and SDH netw...

With the advent of Optical Networks, an important opportunity for the application of Telecommunication Management Network (TMN) framework emerges. At present, most such networks have small or no management capabilities and are characterised by lack of computational resources. Instead of introducing interim proprietary management facilities, the Internet SNMP model is particularly suited for pro...

This paper concentrates on analyzing and discussing the basic secure service: key management (PKey). By adding a security service layer, PKey is carefully built on the base of a routing and location layer to simple the application development. According as the layered architecture of PKey, some key protocols of PKey, which include key producing, retrieving and transferring, are designed and ana...

In this paper we compare the performance of fault localization schemes for communication networks. Our model assumes a number of management centers, each responsible for a logically autonomous part of the whole telecommunication network. We brieey present three different fault localization schemes: namely, \Centralized", \Decentralized" and \Distributed" fault localization, and, we compare thei...

In this paper, we will introduce two different three dimensional VR-based user interface for telecommunication network management. The first one is an immersive system, using HMD and other 3D input devices. The other is a WWW-based flat screen 3D collaborative user interface. The architecture of each system and our observation from it will be described. Then, a comparison will be made to show t...

An global business represents a complex network communication, coordination, and decision making. Information and telecommunication technology (IT) continues to play a crucial role in the organization and management of global businesses. In some cases these systems are enabling fundamental shifts in the structure of global markets. Recognizing the importance of the link between IT and structure...
