面向分布式多媒体服务的通用系统结构(英文)

Towards a General System Architecture for Distributed Multimedia Services

文章描述了一个通用的面向分布式多媒体服务的系统.分布式多媒体服务中用户的不同需求,不仅包括QoS支持,而且包括投射和媒体间转换都能够在这个通用系统结构中很好地加以实现.这个系统结构大大降低了QoS协商的复杂度,更重要的是,通过QoS代理和QoS过滤器的运用,能够根据服务进行时资源的可利用率实现QoS的平滑适应.

A general system architecture for distributed multimedia services is presented in the paper. Diverse user demands, not only QoS support but also Projection and Inter- Media Mapping can be met within this architecture. It can greatly reduce the complexity of QoS Negotiation. Moreover, using QoS Agents and QoS Filters it can gracefully adapt the provided QoS according to the resource availability during the service.
