Service Chain Management Method, Delivery Node, Controller, and Value-Added Service Node

摘要

A service chain management method, a delivery node, a controller, and a value-added service node are provided. An ingress delivery node of a service chain receives a detection packet for detecting the service chain, where the service chain includes at least one value-added service node, and the detection packet carries status information of each value-added service node; and the ingress delivery node determines whether the service chain is in a normal running state according to the detection packet. By using the present invention, management on a service chain can be implemented, thereby improving reliability of the service chain.

主权项

1. A service chain management method, comprising:
receiving, by an ingress delivery node of a service chain, a detection packet for detecting the service chain, wherein the service chain comprises at least one value-added service node, and the detection packet carries status information of each value-added service node; sending, by the ingress delivery node, the status information of each value-added service node to a controller; receiving, by the ingress delivery node, a service allocation instruction that is sent by the controller when the controller determines, according to the status information of each value-added service node, that the service chain is in an abnormal running state; and determining, by the ingress delivery node according to the service allocation instruction, that the running state of the service chain is abnormal, wherein the service allocation instruction comprises allocation information of the service chain and allocation information of a redundant service chain of the service chain, and the redundant service chain is determined by the controller according to the status information of each value-added service node.
