Abstract

The development of new network technologies which offer higher bandwidth as well as the deployment of mobile communications, modern services, multimedia, unlimited Internet access, etc. create numerous problems and questions, e.g. how to interwork existing services with Next Generation Internet, how to manage and optimize  the transmission of growing traffic volumes, how to enhance network performance. In the panoply of tools which help to attack such problems one may find teletraffic theory, performance evaluation and modelling of communication protocols and devices by simulation and mathematical analysis. Mathematical and algorithmic tools are used to solve problems of assuring QoS/QoE, distribution of multimedia, modern routing and switching algorithms including broadcast and multicast traffic control and management, high speed networks, e.g. optical, mobile systems and mobility models, network virtualization. It is easy to conclude that the theoretical analysis of the issues associated with computer networks plays really an important role for any engineer involved in the development of new communications solutions.
