System Wide Information Management (SWIM) is a distributed, large-scale network system that provides uninterrupted aviation information data sharing and transmission services to air traffic management departments, airports and airlines in real time. In order to guarantee the continuity of SWIM services, the emergency response mechanism of SWIM based on subscription/release service was studied. Firstly, by real-time monitoring various performance indicators of SWIM network, a network survivability evaluation method based on improved fuzzy analytic hierarchy process was proposed. Secondly, when the network survivability index fell below the boundary value of the parameter, the corresponding information was published to the subscriber. It was determined by the subscriber whether to perform the service migration. Finally, an Emergency Response Model based on Subscribe/Publish service (ERMSP) for SWIM was proposed for natural disasters and Distributed Denial of Service (DDoS) attacks. The model is based on subscribe, publish and trust management mechanisms. Simulation experimental results show that the resistibility is improved by 8.9% and the business continuity is improved by 18.2% by real-time monitoring of network performance indicators and deployment of ERMSP, which can realize the emergency response of SWIM.

Key words: distributed system, subscribe/publish, System Wide Information Management (SWIM), emergency response
