End-to-End Quality of Service Mechanisms in Next Generation Heterogeneous Networks

A modern communication network can be described as alarge, complex, distributed system composed by higherinteroperating, smaller sub-systems. Today, the proliferation andconvergence of different types of wired, wireless, and mobilenetworks are crucial for the success of the next generationnetworking. However, these networks can hardly meet therequirements of future integrated-service networks, and areexpected to carry multimedia traffic with various Quality ofExperience (QoE) and Quality of Service (QoS) requirements.Providing all relevant QoS/QoE issues in these heterogeneousnetworks is then an important challenge for telecommunicationoperators, manufacturers, and companies. The impressive emergenceand the important demand of the rising generation of real-timeMulti-service (such as Data, Voice VoD, Video-Conference, etc.)over communication heterogeneous networks, require scalabilitywhile considering a continuous QoS. This book presents andexplains all the techniques in new generation networks whichintegrate efficient global control mechanisms in two directions:(1) maintain QoS requirements in order to maximize networkresources utilization, and minimize operational costs on all thetypes of wired-wireless-mobile networks used to transport traffic,and (2) mix the QoS associated with home, access, and core networksin order to provide Quality of Service/Quality of Experienceexpected by users of new services.
