The interaction between a complex socio-economic environment and the extremely fast pace of development of new telecommunication technologies and services justifies the interest in using multicriteria evaluation in decision making processes associated with several phases of network planning and design. Based on an overview of current and foreseen evolutions in telecommunication network technolo...

Telecommunication networks are growing very fast. The user’s needs, in regards to new services and applications that have a higher bandwidth requirement, are becoming bigger every day. A telecommunication network requires early design, planning, maintenance, continuous development and updating, as demand increases. In that respect we are forced to incessantly evaluate the telecommunication netw...

The recent technological advances in world wide web arena with hyper text capable browsers along with the widely available client-server technology has created a new approach to software development in the telecommunication network management industry. Traditionally, network capacity planning and delivery and network information technology software has been custom developed due to the nature of...

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...

We provide information on the Survivable Network Design Library (SNDlib), a data library for fixed telecommunication network design that can be accessed at http://sndlib.zib.de. In version 1.0, the library contains data related to 22 networks which, combined with a set of selected planning parameters, leads to 830 network planning problem instances. In this paper, we provide a mathematical mode...

Mobile communication is nowadays taken for granted. Having started primarily as a service for speech communication, data service and mobile Internet access are now driving the evolution of network infrastructure. Operators are facing the challenge to match the demand by continuously expanding and upgrading the network infrastructure. However, the evolution of the customer’s demand is uncertain....

1 Loss System For a background review, I started the summer vacation scholorship by looking at loss systems. In a telecommunication context, this means that a new coming call is blocked (or lost) if there is no free circuits for that call. First of all, I made myself familiar with the notations. In a loss system, let C be the total number of circuits available, n be the number of circuits in us...
