摘要： 提出了保证型QoS服务的CSBP控制技术，它能够保证每个数据流的预约速率，数据流分组经过网络后有确切的时延上界，核心路由器不需要维持有关每个数据流的状态信息。CSBP控制技术融合了集成服务和区分服务这两大类解决方案的优点，提供了具有高水平的服务质量保证，兼顾了网络资源利用率和扩展性。

Abstract: The article describes CSBP control technology for guaranteed QoS service. It can guarantee the end-to-end delay of per-flow. Data flows get through Net having exact upper delay, and core routes are stateless. CSBP control technology syncretizes the benefits of IntServ and DiffServ, offers high quality of guaranteed services, at the same time it gives attention to the using rate of net resource and extending ability.

Key words: Guaranteed QoS, Core stateless based on per-flow(CSBP), End-to-end delay
