In addition to the traffic growth in the Internet, new applications and services are imposing a large variety of requirements. At the same time, the emergence of network applications on video, audio, business services, and other data ser-vices is creating an imminent demand for integration of most traffic with de-fined quality of service (QoS) guarantees. Examples of emerging network re-quirements are directly related to reliability, recoverability, and security. Al-though most of these requirements have kindled research interests in recent years, it is still unclear how to integrate them for next generation networks. To manage the increasing variety of QoS requirements, this research project pro-poses a new service model concept, called service vector, as a solution for pro-viding QoS support for a large variety of traffic classes. This concept is expected to help achieving the following objectives: a) robust differentiated service model capable of supporting fine QoS granularity; b) scalability; c) satisfaction of the users' customized end-to-end requirements; d) improved network operator revenue; e) higher utilization of the current Diffserv network model. The com-plexity and feasibility of service vectors for the next generation networks is in-vestigated, and the impact on router architectures and deployment issues are considered for the implementation of service vectors in new-generation and de-ployed routers.

除了互联网中的流量增长之外，新的应用和服务也提出了各种各样的要求。与此同时，视频、音频、商业服务和其他数据服务上的网络应用的出现，正在产生一种迫切的需求，即将大多数流量与确定的服务质量（QoS）保证相集成。新出现的网络需求的示例与可靠性、可恢复性和安全性直接相关。尽管这些需求中的大多数近年来引起了研究兴趣，但如何将它们集成到下一代网络中仍然不清楚。为了管理日益多样化的QoS需求，本研究项目提出了一种新的服务模型概念，称为服务向量，作为一种解决方案，为各种各样的业务类提供QoS支持。该概念有望帮助实现以下目标：a）能够支持精细QoS粒度的鲁棒的区分服务模型; B）可扩展性; c）满足用户定制的端到端需求; d）提高网络运营商的收入; e）更高地利用当前的Diffserv网络模型。分析了下一代网络中业务向量的复杂性和可行性，并考虑了业务向量在新一代和已部署路由器中的实现对路由器体系结构和部署问题的影响。
