METHOD AND APPARATUS FOR IMPLEMENTING MPLS-BASED NETWORK DETECTION, NETWORK DEVICE, AND CONTROLLER

摘要

Disclosed are a method and apparatus for implementing MPLS-based network detection, a network device, and a controller. The method comprises: a node in a detection domain determines information of a detection object and a detection task, wherein the information of the detection object comprises an object identifier; when the node is the header node of the detection domain, identify a service packet matching the detection object from a received service stream, add the object identifier to the MPLS tag of the service packet, and forward the service packet comprising the object identifier; when the node is the header node, intermediate node, or tail node of the detection domain, perform a detection operation on the service packet comprising the object identifier according to the detection task.
