The existing service migration methods bring the server cluster heavy burden, and their time spending is so high that seriously affects the service continuity. In order to enhance the survivability of IP network services, the paper puts forward an intent-perceptible service migration model (ISM). In this model, we design a novel trigger mechanism and object selecting method for service migration, and make the service migration intention perceptible for the client with the cooperation of the server. The evaluation results show that ISM model can not only ensure the service invulnerability by maintaining a high randomness of service migration, but also improve the service continuity by reducing the service gap time spending on service migration to the maximum extent. Therefore, ISM model can enhance IP network survivability efficiently.
