Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such
as VoIP and videoconferencing. The “best effort” Internet delivery cannot be used for the new multimedia applications.
New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications.
Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate
communications. The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough
resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures,
differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing
of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different
QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile
wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and
ubiquitous access in a market, where the demand for mobile Internet services has grown rapidly and predicted to generate
billions of dollars in revenue. It covers the issues of QoS provisioning in heterogeneous networks and Internet access over
future wireless networks as well as ATM, MPLS, DiffServ, IntServ frameworks. It discusses the characteristics of the Internet,
mobility and QoS provisioning in wireless and mobile IP networks. It also covers routing, security, baseline architecture of the
inter-networking protocols and end to end traffic management issues.
