A service function chain (SFC) path selection method. The disclosed method receives an SFC request for scheduling an SFC, rearranges SFC with respect to the workload of service function forwarders (SFFs) utilized in the SFC while conforming to SFC arrangement rules concluded from a history of deployed SFC. The SFC arrangement rules may be created from machine learning processes or manually created by an administrator.

A network detection method links multiple nodes residing in a network topology to form multiple edges and creates snake paths through the edges using a snake algorithm. The routing frequencies of each of the snake paths is calculated, and software-defined network (SDN) policy flows to each of the nodes are produced and applied. The health and performance status, and available bandwidths, of the snake paths are dynamically detected via packet flows using a pathChirp bandwidth detection method.

Network detection method and controller using the method

A network service method based Software Defined Networking (SDN) assigns forwarding devices according to network addresses and identification of a client and provides the client with an optimum route according to user requirements and current network states. A continuous monitoring process is continuously performed for route optimization based on network states, topology variations, and user feedbacks.
