Various example embodiments for supporting application-based traffic control in a multipath network are presented herein. Various example embodiments for supporting application-based traffic control in a multipath network may be configured to support application-based traffic steering, application-based traffic blocking, or the like, as well as various combinations thereof. Various example embodiments for supporting application-based traffic control in a multipath network may be configured to support application-based traffic control in various types of multipath networks, such as multipath networks combining wireline and wireless access technologies between an end-user customer premises and a network gateway (e.g., between a hybrid-access customer premises equipment (HCPE) and a hybrid-access gateway (HAG), in a hybrid-access communication network (e.g., based on a Broadband Forum TR-348 specification), that are in communication based on a multipath communication capability), multipath networks combining multiple wireless access technologies (e.g., cellular, WiFi, or the like) between an end user mobile device and a network gateway, or the like.
