Handling multipath flows in service function chaining
Abstract:
A service classifier network device receives a subflow and identifies that the subflow is one of at least two subflows in a multipath data flow. Related data packets are sent from a source node to a destination node in the multipath data flow. The service classifier generates a multipath flow identifier and encapsulates the subflow with a header to produce an encapsulated first subflow. The header identifies a service function path and includes metadata with the multipath flow identifier.
