概述过去十年互联网技术的进步已将技术重点从可达性转移到通信质量上。有许多技术框架，如集成服务和区分服务，它们已经标准化，以确保通信质量。Qos路由也是这样的框架之一。它改变或固定了IP数据报所采用的路径，也是实现各种服务所不可缺少的。然而，在运营网络上进行服务质量路由的实验报道很少，尤其是在动态SLA的情况下。因此，我们仍然不太清楚实现Qos网络的重要因素，如用户行为、提供合适的服务以及配置参数。本文在2000年秋季大撤退建设的实际网络中，进行了伪服务质量路由和动态SLA的现场测试。在这次实地测试中，我们为与会者提供了两种不同类型的链接。与会者选择了我们的动态SLA中的一个链接，他们的流量通过该链接进行传递。我们描述了这个实验的细节和结果。我们的结果可以帮助理解客户对区分服务的行为，因此对设计和部署各种服务质量技术是有用的。
SUMMARY Improvements of Internet technology during the last decade have shifted the technical focus from reachability to the quality of communication. There are many technical frameworks,such as Integrated Service and Differentiated Services, which have been standardized to assure the quality of communication. QoS routing is also one of such frameworks. It changes or fixes a route that IP datagrams take,and is also indispensable to put a variety of services into practice. Nevertheless,experiment reports of QoS routing on operational network are quite few,especially with dynamic SLA. Therefore,we still do not know much about the important factors for QoS-enabled network to be realized,such as users’ behavior,suitable services to offer,and configuration parameters. In this paper,we carried out field-trial with pseudo QoS routing and dynamic SLA in an actual network built at the WIDE retreat in autumn 2000. In this field-trial, we provided two different types of links to attendees. Attendees chose one of the links,through which their flows go,with our dynamic SLA. We describe the details and the results of this experiment. Our results could help to understand the customers’ behavior for differentiated services,and therefore be useful for designing and deploying various QoS technologies.
