Abstract: Contemporary information and communication services, specifically their functionalities| level and range, the way it is achieved as well as the end-users| satisfaction, are developing much faster than ever before. The strong drive for these services| fast development and deployment has not been accompanied by a proper understanding of their engineering and design principles, and for the most part, the services| satisfactory qualitative performance is being obtained by the strength approach of over-provisioning. Consequently, there is a strong need for a deeper quantitative understanding of the services| functioning, an understanding that leads to clear design and control methods those in turn make the services| efficient deployment and exploitation possible. Thus, the research performed within this paper covers analytical and design aspects of technical and economic challenges emerging in multiservice networks, and was conducted from a methodological perspective of evolving network infrastructure.
