This patent application describes an intelligent method/system for flow classification for network and service function chaining. A chain is an ordered sequence of network/service entities. However, the method described here can be equally applied to any unordered sequence (a group) of network/service entities as well. The Network functions (NFs) can be physical or virtual or a combination of both in the chained path. The Service functions (SFs) can be physical or virtual or a combination of both in the chained path. The proposed Classifier is intelligent in the sense that it learns and adapts to the requirements of the flows (or a stream of packets), and significantly improves the pre-processing time (and overheads) for flow classification, and hence forwarding. |
