金融信息系统要求有很高的抗毁能力,针对现有的SOA技术在抗毁方面的应用,首次提出将自组网络技术、P2P技术与面向服务架构结合起来,利用自组网络的无中心特点解决了SOA架构对集中式注册中心的依赖;利用自组网络的快速拓扑重构能力,可以实现基于SOA的金融信息系统在受损后的快速重构和运行;利用P2P机制的多副本特性,实现服务与服务描述的多处备份运行与存放,并在服务无法正常提供的情况下,自动发现和启用新的同等服务,从而保证金融信息系统的抗毁能力。
Financial information system requires strong anti - disaster capability. A framework combining Ad Hoc network and P2P techniques with Service- Oriented Architecture (SOA) is firstly proposed. This framework inherits the rapid topology reconstruction capability of Ad Hoc network after disaster. The multi - copy storage ability of P2P system is applied for service documentation and backup. Also, the P2P system's automatic service identification and discovery features are used when the normal service is not available, which guaranteed the robustness of financial information system.
