The invention provides a service orchestration system and method based on intention in an intelligent fusion identification network. The system comprises an intelligent service layer used for receiving a service request proposed by a user, performing user service intention translation in an intention perception knowledge base according to the service request, translating the user service intention into a service demand behavior description SBD of network service, and determining a network service type; a resource adaptation layer which is used for generating a service orchestration strategy by utilizing the ethnic group management strategy library according to the SBD of the network service, the network service type and the current network state information of the network component layer; and a network component layer which is used for executing the service orchestration strategy, and storing and forwarding data through a network component corresponding to the service ethnic group in the service arrangement strategy. According to the invention, the network can intelligently sense differentiated service requirements of massive services, effective management and efficient utilization of complex network resources are realized, and the flexibility, scalability and the like of the network are improved.
