| 资源预约是保证分布式多媒体应用服 务质量(QoS)的重要手段.提出一个应用级QoS协商算法,该算法有两个主要优点:一是局部参 数全局化,使预约变得灵活,便于直接对用户所关心的QoS参数进行预约;二是全局预约局部化 ,使预约变得简单,有利于实现最优延时分配. |

| Abstract: |
| Resource reservation is an important means to guarantee the QoS of distributed m ultimedia applications. In this paper, an application level QoS negotiation prot ocol is proposed. It has two merits. One is globalizing the local QoS parameters so that the reservation becomes more flexible and users can reserve resources u sing the parameters they concern. The other is localizing the global reservation to make reservation simpler and to facilitate the implementation of optimal del ay allocation. |
| Key words: distributed multimedia QoS application level resource reservation optimal del ay allocation |
