Service chain realization method and strategy control platform

The invention discloses a service chain realization method and a strategy control platform. The strategy control platform comprises a segment routing label management module and a source routing path generation module. The service chain realization method comprises the steps of establishing corresponding relationships between segment routing labels and service types of nodes in a whole network; searching corresponding node segment routing labels according to service types of user requests; and generating source routing paths between user terminals and the nodes marked by the node segment routing labels. The paths of special traffic can be appointed dynamically through segment routing, so a user service processing function can be dynamically configured, and the user service can be scheduled and processed according to demands. 本发明公开了业务链实现方法以及策略控制平台。该策略控制平台包括：分段路由标签管理模块和源路由路径生成模块。业务链实现方法包括：建立全网节点的分段路由标签与业务类型的对应关系；根据用户请求的业务类型，查找对应的节点分段路由标签；生成用户终端到节点分段路由标签所标示的节点之间的源路由路径。由于分段路由可以动态指定特定流量的路径，因此可以实现用户业务处理功能的动态配置，可以实现
