Method and system for constructing flexible networking linkage management based on native IPv6

The invention discloses a method and a system for constructing flexible networking linkage management based on native IPv6 (Internet Protocol Version 6), a flexible network based on service awareness is constructed through linkage management and control of a controller and an edge router, and the edge router completes self-configuration of the edge router based on configuration issued by the controller and realizes rapid network access and service opening of the edge router; the edge router completes terminal device address distribution, flow identification and mapping packaging based on IPv6 address planning and service information issued by the controller; a northbound interface and a southbound interface of the controller are defined, the northbound interface provides business configuration and data analysis capability upwards, and the southbound interface provides edge router management capability downwards, relying on the open programming capability of the northbound interface, provides business-based sc
