Abstract

Abstract: Based on relevant research, a discovery model of Quality of Service (QoS) was proposed. The model provides a set of dynamic performance testing of services and a negotiator with a counter offer mechanism, in order to filter and sort according to QoS, which can mostly meet customer demand through negotiation. The effectiveness and availability of the discovery system can be enhanced, which is verified through experiments.

摘要： 在分析了相关研究的基础上，提出了一种基于服务质量（QoS）的服务发现模型。该模型可对服务进行动态性能测试并提供一种带有还盘的协商机制，对检索到的服务进行过滤和选择并按服务质量进行排序，经过协商选出最符合客户需求的服务。通过实验证明可以提高发现系统的有效性和可用性。
