摘要：

针对SOA应用系统中的服务动态扩展问题进行研究，提出了基于SOA的服务动态扩展系统模型，该模型在SOA架构的基础上，引入了服务资源池和服务动态扩展思想，把系统可用服务放入资源池中供系统调用，通过调整资源池的服务组成和规模实现服务动态扩展。本文给出了系统模型框架和服务动态扩展的功能逻辑，并使用ASML语言描述模型中的动态扩展规则，最后使用Spec Explorer对系统模型进行仿真测试，验证了系统的可行性和有效性。

关键词: 服务动态扩展, 服务资源池, SOA, ASML

Abstract:

Aiming at the challenge to realize the service dynamic extension in service-oriented architecture（SOA）, a service dynamic expansion mechanism based on SOA is proposed. Services pool and service dynamic extension idea are introduced to this service dynamic expansion system model, and the services are designed into the form of services pool to be called by the system, and the system realizes the service dynamic extension by administrating the resource pool. The critical processes of the service dynamic extension rules are written in ASML（abstract state machine language）. Last spec explorer is used to test the model, validating its feasibility and validity.

Key words: service dynamic-extension, service resource pool, SOA, ASML
