Abstract
In a network control plane, a pattern matching database is built and maintained for identifying an application or application level protocol. In addition, pattern matching databases for predicting a subsequent flow for application layer/level protocols or data protocols are built and maintained. After flow differentiation in network traffic mirrored from a data plane, the network traffic flow is scanned in a first stage and then in a second stage if a signaling protocol message is detected in the first stage scan. For the second stage, one of the application/data protocol pattern databases is selected for scanning based on the signaling protocol message detected in the first stage scanning. If a match is found from the stage 2 scanning, a mapping between the signaling protocol identifier and an identifier for a predicted application traffic flow is created and communicated to the data plane for policy selection and enforcement.
