SOA-Based Service Survivability in Financial Information System

Financial information system requires strong service survivability capability. A framework combining ad hoc network and P2P techniques with service-oriented architecture (SOA) is firstly proposed for this purpose. The non-centre characteristic of ad hoc network is used to remove the relationship of the SOA depending on the universal discovery description and integration(UDDI). The framework inherited 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 survivability of financial information system.
