| 摘 要： | 针对ISP在提供实时多媒体服务时对灵活性的需求，设计了一个基于覆盖组播的实时流网络模型，利用面向服务的方法传送语音、视频等流数据，改善了实时流应用中的QoS，较好地解决了ISP部署多媒体增值服务业务的灵活性问题。并结合NUQ应用实例，从服务控制和资源管理的角度，研究组合实时流服务和构件来实现组通信服务，并分析了满足QoS和控制资源的方法。 |
| 关 键 词： | 实时流 覆盖组播 服务组合 面向服务的体系结构 服务控制 |

| Abstract: | To improve the flexibility in multimedia service for Internet Service Provider(ISP),a live streaming service composition model is addressed.This is an overlay multicast network based on service-oriented methods for transmiting the continuous media data,like audio,video etc.It can achieve the QoS-aware live media applications for ISP's value-added business.Then,an instance called NUQ,is designed and applied according to the model.In NUQ,the composition of the services and the components is discussed in order to improve the service controll and resource management,at last the QoS-satisfied and resource-controlled methods is studied. |
| Keywords: | Live streaming Overlay multicast Service composition Service-oriented architecture(SOA) Service controll |
