Abstract:
Based on OGSA, this paper proposes an effective model for grid Web component resource organization, which considers service choice-making based on QoS. The organizing protocol and data structures required for implementing the model are given. The prototype implementation shows that framework is reasonable and effective, and it provides guarantee of the reliability of Web service assemble and service QoS.

摘要: 在基于OGSA框架基础上,提出了基于QoS资源动态选择性定位的网格Web构件组织模型。描述了该模型实现机制、组织协议和数据结构,研究了中间层的QoS服务机制。通过对原型系统的模拟表明该模型是合理和有效的,能够为Web构件集成的服务动态选择性奠定基础。
