| 摘 要： | 基于SLP设计一个支持QoS约束的服务发现模型QCSLP，在使用DA工作模式的SLP中设计一个QoS管理者实体QM，支持QoS的计算和反馈，引入QoS标准化和综合QoS的概念，根据用户反馈信息对服务的QoS进行动态评估和调整。通过具有6个实体的模拟局域网环境验证结果表明，QCSLP能帮助用户发现满足其类型、属性以及服务质量要求的服务。

| Abstract: | A QoS constrained service discovery model QCSLP is proposed. An entity of QM is designed in the existing Service Location Protocol(SLP) working pattern based on DA to mainly support the calculation and feedback of QoS. The conception of QoS standardization and integration is imported and the mechanism of QoS feedback is adopted in the QM entity. Experimental result shows that QCSLP can help user find services that meet the service requests of type and attribute, and the service requests of QoS at the same time in the simulation environment of LAN including 6 entities. |
