Method and apparatus for network management

The invention relates to a method and equipment for network management. In general, this disclosure describes techniques for dynamic application service level agreement (SLA) metric generation, distribution, and intent-based SD-WAN link selection. For example, a network device may determine metrics associated with an application or group of applications. The network device may send metrics to the controller, and in response, may receive recommended SLA metrics associated with the application or group of applications from the controller. The network device may also compute an intent-based SLA metric based on the recommended SLA metric, one or more characteristics of one or more links connected to the network device, and a user-configured intent model defining a tolerance level to apply the recommended SLA metric. A network device may select a path to send traffic from an application or group of applications according to an intent-based SLA metric. 本公开涉及用于网络管理的方法和设备。总体上，本公开描述了用于动态应用服务等级协议(SLA)度量生成、分发和基于意图的SD-WA
