The disclosure relates to automating a balanced configuration of traffic monitoring filters to monitor traffic in a production network. A deployment in accordance with the disclosure includes a production network and a monitoring fabric. The production network includes a network controller to configure and provide information about the production network, and likewise the monitoring fabric includes a controller to configure and provide information about the monitoring fabric. A filter agent can create traffic monitoring rules that constitute user-defined traffic monitoring filters, and deploy the rules in a balanced fashion across devices in the production network and in the monitoring fabric using information queried from the production network controller and the monitoring fabric controller. The filter agent can redeploy traffic monitoring rules in response to changes in the operating environment.

Automated configuration of filters to monitor production network traffic

A packet forwarding network may include switches that forward network packets between end hosts. A monitoring network may be coupled to the forwarding network. A controller may control switches in the monitoring network to forward network packets tapped from the forwarding network to one or more packet recorders. The packet recorders may store the tapped packets and the controller may query the stored packets at a later time. The controller may analyze queried packets to monitor the operation of the packet forwarding network and, if desired, to display graphical visualizations associated with the packet forwarding network. If desired, the controller may instruct the packet recorders to replay the tapped packets to network visibility tools through the monitoring network. The controller may coordinate storage and query operations across multiple packet recorders using the monitoring network so that the packet storage capacity and recording rate may be scaled up over time.

Systems and methods for controlling switches to record network packets using a traffic monitoring network

A networking system may include a first network such as a private cloud network and a second network such as a public cloud network. The first network may include a switch coupled to a computing resource. To facilitate a robust and flexible inter-network connection, the networking system may include network connector circuitry having a connector endpoint at the first network and a network connector coupling the connector endpoint to a network element at the second network. A controller for the first network may provide control signals and configuration data to the network connector circuitry to form the connection to the second network and may configure the switch to forward external network traffic to and from the connector endpoint via a switch port directly coupled to the connector endpoint.

Systems and methods for providing network connectors

Systems and methods for building a monitoring fabric are described. The system receives a duplicate of a first portion of traffic information from a first network as first traffic information and communicates the first traffic information in the monitoring fabric. The first traffic information is communicated to a controller that configures the monitoring fabric. The system receives a duplicate of a second portion of the traffic information from the first network as second traffic information. The system forwards the second traffic information to at least one tool.
