由于互联网正在经历着实质性的变化，对通信的质量提出了许多要求。差异化服务被标准化以满足这些要求。目前，假设DiffServ在静态服务等级协议(SLA)下使用。在静态SLA下，服务提供商和服务订阅者之间的协议是由人工代理之间协商的结果。然而，服务订户，尤其是个人用户，可能需要动态SLA，他们可以在没有人工干预的情况下与其签订合同，并立即使用网络资源。虽然很多文献都提到了这一点，但动态SLA在实时网络下的运行还没有得到应用。此外，关于动态二语习得的实验也很少。本文描述了我们在Wide Project春季度假地进行的动态SLA和资源预留系统的现场试验，包括它的网络配置和试验结果。通过这个实验，我们试图揭示用户在动态SLA下的行为，以及这样的系统需要什么样的机制。
As the Internet is undergoing substantial changes, there are many demands for the quality of the communication. Differentiated Services was standardized to meet such requirements. Currently, it is assumed that Diffserv is used under static Service Level Agreement (SLA). Under static SLA, the agreement between the service provider and the service subscribers are made as a result of negotiation between human agents. However, the service subscribers, especially individual users, may want dynamic SLA with which they can make their contract without human intervention and use the network resources immediately. Although many literatures addressed this point, operation of dynamic SLA under live network has not been applied. Moreover, only few experiments for dynamic SLA has been made. In this paper, we describe our field-trial with dynamic SLA and resource reservation system at the spring retreat of WIDE Project, including its network configuration and the results of trial. Through this experiment, we attempt to reveal that how users behave with dynamic SLA, and what mechanism such system needs.
