Guaranteed multipoint communication support for multimedia applications

Multimedia applications require besides basic communication services the particular support of guaranteed end-to-end services. In addition, these services need to be of a multipoint nature, where group communications take place in a guaranteed fashion as well. Therefore, a Quality-of-Service- driven specification of application requirements for multipoint scenarios and the guaranteed provision has been developed. At the same time, multipoint dynamics in terms of joining or leaving participants have been integrated, still guaranteeing end-to-end performance. In contrast to other communication frameworks, Quality-of-Service mechanisms and multipoint communication support are not considered as orthogonal, but an integration of these aspects leads to an efficient and highly flexible approach. Resource reservation, flexible protocol stacks, and heterogeneous network support are provided to guarantee multipoint multimedia application communication services in an end-to-end fashion.
