Abstract: A network node may contain a virtual software-defined networking (SDN) switch and a local a management engine (e.g., a software application) for generating performance metrics based on received management plane traffic. Specifically, the virtual SDN switch may identify and forward received management plane traffic to the local management engine. In turn, the management engine evaluates the management plane traffic to generate performance metrics without forwarding the management plane packets to the remote SDN controller. The management engine may compare the metrics to one or more thresholds to determine the current state or health of the data paths in a network. If a threshold is exceeded, the management engine may transmit an alert to the virtual SDN switch to perform a corrective action—e.g., using a backup data path after the primary data path fails.

Abstract translation: 网络节点可以包含虚拟软件定义网络（SDN）交换机和本地管理引擎（例如，软件应用程序），用于基于接收到的管理平面业务来生成性能度量。 具体地说，虚拟SDN交换机可以识别并转发接收到的管理平面流量到本地管理引擎。 反过来，管理引擎评估管理平面流量以生成性能度量，而不将管理平面数据包转发到远程SDN控制器。 管理引擎可以将度量与一个或多个阈值进行比较，以确定网络中数据路径的当前状态或运行状况。 如果超过阈值，则管理引擎可以向虚拟SDN交换机发送警报以执行纠正措施，例如在主数据路径发生故障之后使用备份数据路径。
