现代通信网络可以被描述为一个大型的、复杂的、分布式的系统，它由更高的互操作、更小的子系统组成。今天，不同类型的有线、无线和移动网络的扩散和融合对下一代网络的成功至关重要。然而，这些网络很难满足未来综合业务网络的需求，并且需要承载各种体验质量（QoE）和服务质量（QoS）要求的多媒体业务。因此，在这些异构网络中提供所有相关的QoS/QoE问题是电信运营商、制造商和公司面临的一个重要挑战。实时多业务（如数据、语音VoD、视频会议等）在通信异构网络上的出现和重要需求令人印象深刻，在考虑连续QoS的同时需要可扩展性。本书介绍并解释了新一代网络中的所有技术，这些技术在两个方向上集成了有效的全局控制机制：(1)保持QoS要求，以便最大限度地利用网络资源，并将用于传输流量的所有类型的有线-无线-移动网络的运营成本降至最低；(2)混合与家庭、访问、和核心网络，以提供新服务的用户所期望的服务质量/体验质量。
A modern communication network can be described as a large, complex, distributed system composed by higher interoperating, smaller sub-systems. Today, the proliferation and convergence of different types of wired, wireless, and mobile networks are crucial for the success of the next generation networking. However, these networks can hardly meet the requirements of future integrated-service networks, and are expected to carry multimedia traffic with various Quality of Experience (QoE) and Quality of Service (QoS) requirements. Providing all relevant QoS/QoE issues in these heterogeneous networks is then an important challenge for telecommunication operators, manufacturers, and companies. The impressive emergence and the important demand of the rising generation of real-time Multi-service (such as Data, Voice VoD, Video-Conference, etc.) over communication heterogeneous networks, require scalability while considering a continuous QoS. This book presents and explains all the techniques in new generation networks which integrate efficient global control mechanisms in two directions:(1) maintain QoS requirements in order to maximize network resources utilization, and minimize operational costs on all the types of wired-wireless-mobile networks used to transport traffic, and (2) mix the QoS associated with home, access, and core networks in order to provide Quality of Service/Quality of Experience expected by users of new services.
