Managing global calls placing in mash-upped enterprise

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.
