Title: METHOD AND APPARATUS FOR MANAGING COMMUNICATION FLOW IN AN INTER-NETWORK SYSTEM
Abstract:
According to at least one example embodiment, a method and corresponding apparatus for managing a data packet flow at an inter-network system include obtaining, by an inter-network device, an identification of the data packet flow, the identification of the data packet flow being determined based on one or more transport protocol fields extracted from control-plane data associated with the data packet flow. Using the obtained identification of the data packet flow, the inter-network device identifies data packets associated with the data packet flow by checking transport layer data of intercepted user-plane data packets for potential match with the one or more transport protocol fields extracted from the control-plane data. If a match is found, the corresponding data packet is then managed by the inter-network device based on one or more management actions associated with the data packet flow.
