Zunguo Huang · Jisuanji gongcheng · 2008
Service migration should include three types of state——initial state, active state and complete state. Based on these, this paper proposes the architecture of service migration and analyzes the realization of service migration. When facing security threat, service migration determines whether to migrate, either actively or passively. It is transparent to the users so that they will not feel the change of service. It just migrates the service states with the purpose of shorting migration time by reducing transmitted data. The migration of FTP service is realized.
