Multimedia Networking. Coordination of Multimedia Services in Next Generation Mobile Networks

      Аннотация: Revision with unchanged content. The realization of ubiquitous access to Internet services in the next generation of mobile networks (NGN) needs to address the increasingly important challen­ges of networks cross-bridging, mobility and Quality of Service (QoS) for different kinds of multimedia services. Current mechanisms for providing QoS cover predominantly single facets of the global QoS management. However, QoS is a system aspect that crosses all components and layers of a distributed multimedia system. Consequently, the control mechanisms for service management turn to be increasingly complex with the growing system heterogeneity. Significant parts of this work are devoted to the opti­mi­sation of the control signalling for distributed multimedia services. The major topic of this work is the specification and the implementation of the End-to-End Negotiation Protocol (E2ENP). The protocol represents a novel approach to manage multimedia services in mobile and heterogeneous networks, different from the currently existing static service-coordination methods. This book is the publication of the doctor thesis of T. Guenkova-Luy and it addresses the topics of optimization of the multimedia-management systems in NGN.
