Abstract
A data and control plane architecture for network devices. An example system architecture includes a network processing unit implementing one or more data plane operations, and a network device operably coupled to the network processing unit that implements a control plane. In a particular implementation, the network processing unit is configured to process network traffic according to a data plane configuration, and sample selected packets to the network device. The network device processes the sampled packets and adjusts the data plane configuration responsive to the sampled packets. In particular implementations, the control plane and data plane implement a server-side triggered policy caching mechanism that allows for previous classification policy decisions made for previous data flows to be applied to subsequent new flows.
