Estimating the term…
Network policies that control the flow of traffic through a network may be implemented using a controller server that controls a network of switches. Based on network packet attributes, the controller server may identify network policies that are associated with the network traffic. The controller server may identify dependencies between the network policies based on priorities that are associated with the network policies and overlap between the network policies. The controller server may provide the switches with packet forwarding rules based on the identified dependencies between the network policies, network switch attributes, and network switch capabilities. The packet forwarding rules may implement network policies for current network traffic and future network traffic.
A method of using a controller to control network switches in a network, wherein packets having packet attributes flow through the network, the method comprising:
A method of using a controller to control network switches in a network, wherein packets having packet attributes flow through the network and are subject to network policies, wherein each network policy specifies an action to perform on the packets when the packet attributes of the packets satisfy matching criteria associated with that network policy, the method comprising:
