Teletraffic phenomenon in classical and new telecommunication networks can be more systematically described and different system-type problems can be effectively solved using fundamental concepts of systems and GSPS (General Systems Problem Solver) methodology. Basic presupposition is that general systems methodology is usable as a logicomathematical methodology in formulation, derivation and e...

In this chapter, the main principles of the theory of fractals and multifractals are stated. A singularity spectrum is introduced for the random telecommunication traffic, concepts of fractal dimensions and scaling functions, and methods used in their determination by means of Wavelet Transform Modulus Maxima (WTMM) are proposed. Algorithm development methods for estimating multifractal spectru...

Synthetic mobility models can be used to simulate the movement of a traffic unit or a group of traffic units in a telecommunication network. Characteristics of pedestrian and vehicular traffic, such as speed-flow, speed-density and flow density are often neglected in current synthetic mobility models. The analysis, emulation and simulation of telecommunication networks with mobile users using m...

The MPLS Transport Profile (MPLS-TP) is based on a profile of the MPLS and Pseudowire (PW) procedures as specified in the MPLS Traffic Engineering (MPLS-TE), PW, and Multi-Segment Pseudowire (MS-PW) architectures developed by the Internet Engineering Task Force (IETF). The International Telecommunication Union Telecommunication Standardization Sector (ITU-T) has specified a Transport Network ar...

Network redimensioning (medium term planning) means to determine volume of telecommunication resources, necessary to serve given traffic offered taking into account the prescribe Quality of services (QoS). Two different network redimensioning methods are considered in this paper. The aim of the research is comparison between network redimensioning method, using ITU E.600 traffic offered definit...

With the rapid evolution of telecommunication networks, real-time network traffic management is becoming more and more crucial. We propose here a modular system for performing diagnosis at different levels of the network. It is designed as an aid to the operator. We present results of different experiments with a first version of this system which operates at a local level.

For many years, the evolution of telecommunication networks and the enabling technologies followed an almost prescriptive mechanism, based on a hierarchical arrangement of local, regional and national/international voice switching telephone exchanges. Growth in traffic was fairly predictable, determined mainly by the rate of telephone take-up, with a smattering of higher speed (n × 64 kbit/s an...

Telecommunication network topologies are changing nowadays. The core telecommunication networks are based on fiber optics infrastructure. WDM technology is used to transmit multiple flows of traffic over a single fiber. Virtual network topology (VNT) is used to route IP traffic over WDM networks. VNT control system must be adaptive to traffic changes and dynamically reconfigure VNT. Langevin eq...
