    Abstract: Disclosed is a method for continuous in-line monitoring of data-centric traffic to guarantee application performance. The method includes, in each switch of a plurality of switches in a network fabric, grouping all packets entering each respective switch of the plurality of switches based on either 5-tuple applications or EPG based applications, collecting performance statistics at every hop in the network fabric across all flows in-line in a flow table maintained in each respective switch and periodically exporting the performance statistics to analysis module.

    Abstract: A determination is made at a network connected device that a network policy is to be verified. The network policy is applied to network packets sent to an endpoint within a network, and the application of the policy to network traffic can result in at least two outcomes. Another determination is made at the network connected device that a switch is provisionable to host the endpoint. The network connected device provisions a simulated endpoint version of the endpoint at the switch to host the policy. At least one packet is sent to the simulated endpoint via the network connected device for each of the at least two outcomes of the policy. At least one response is received by the network connected device from the simulated endpoint indicating how the policy was applied to each of the packets.

    Abstract translation: 在网络连接设备上确定要验证网络策略。 网络策略被应用于发送到网络中的端点的网络分组，并且策略对网络流量的应用可以产生至少两个结果。 在网络连接设备上进行另一个确定，即交换机可用于托管端点。 网络连接设备在交换机上提供端点的模拟端点版本以承载策略。 对于策略的至少两个结果中的每一个，至少一个分组经由网络连接的设备发送到模拟端点。 网络连接设备从模拟端点接收至少一个响应，指示策略如何应用于每个分组。
