This paper presents the Cross Infrastructure Attack Attribution Toolkit (CAT), which is a utility to analyze the vulnerability of 3G networks using telecommunication specifications. CAT analyzes vulnerabilities by generating attack graphs, which show the global view of the network in the event of an attack. The uniqueness of CAT is as follows: (1) usage of telecommunication specification writte...

Fuzzy inference method based approach to the forming of modular intellectual system of assessment the quality of communication services is proposed. Developed under this approach the basic fuzzy estimation model takes into account the recommendations of the International Telecommunication Union in respect of the operation of packet switching networks based on IPprotocol. To implement the main f...

This paper presents a reliability analysis of Local Exchange Carrier telecommunication switches in the United States, based upon empirical data. Telecommunication switch outage statistics are analyzed for a multiyear period, allowing examination into switch failure frequency, causes, and trends. Failure categories are created by reported outage cause codes, including human error, design error, ...

The paper describes development of intelligent system, based on integration of simulation, expert, situational and multi-agent simulation, as well as object oriented approach. The developed decision support system was applied for multi-service telecommunication networks design and telecommunication services area business processes dynamic simulation. Paper starts with prerequisites for developm...

This paper presents the concept of green telecommunication networks and provides information about the power consumption within fixed line and wireless communication networks. It outlines the significance of energy efficiency in modern and future telecommunication networks and suggests directions for optimizing network performance in terms of energy demands. Numerous examples and reviews are al...

A business model framework is presented which is derived from the literature to aid the development of viable business models expected from the amalgamation of mobile telecommunication and space infrastructure. With examples for the global mobile telecommunication industry, this theoretical paper will illustrate the importance of technological and organizational co-operation between the various...

A computer network management system presents one manager and several agents. The management of large networks demands much computer resources and management system capacity, impossible to achieve with just one manager. The TMN standard, that intends to standardize management systems for telecommunication networks offering those resources, already foresees the use of several managers organized ...

This article discusses the architecture, control protocols, and coordination mechanisms used in today’s multimedia Ž . Ž . conferencing standards for ISDN Integrated Services Data Network and IP Internet Protocol networks. Specifically, the Ž . ITU-T’s International Telecommunication Union – Telecommunication Standardization Sector H.320 and H.323 multimedia conferencing standards are discussed...

The recent emergence of multimedia applications has led to the deployment of various telecommunication technologies (e.g. IP, wireless) in addition to traditional PSTN (Public Switched Telephone Network) circuit switched networks. In this heterogeneous telecommunication world, users make calls without regard to the fact that the originating network may differ from the terminating network, and t...
