Abstract: A method of reporting congestion in an upstream direction in a service chain function architecture. The method includes receiving, by the downstream device, a packet indicating congestion within a service function chaining architecture; generating, by the downstream device, a congestion report message in response to receiving the packet, wherein the congestion report message comprises a field indicating an existence of congestion within the service function chaining architecture and a service path identifier indicating a location of the congestion within the service function chaining architecture; and transmitting, by the downstream device, the congestion report message to an upstream device to permit the upstream device to address the congestion.

Abstract: A method for using metadata in an Internet Protocol (IP) packet is provided. A first processor at a first node sets a dedicated field of the IP packet to a predetermined value to indicate that metadata is present in the IP packet, and adds metadata to the IP packet by inserting the metadata between an original transport header of the IP packet and an original packet payload of the IP packet. A second processor at a second node receives the IP packet from the first node, reads the dedicated field to identify the predetermined value indicating that metadata is present in the IP packet, and identifies the metadata in the IP packet based on the predetermined value.

Abstract: A network device employs a transmitter configured to transmit a registration request to a software defined network (SDN) controller. The network device employs a receiver to receive a reply from the SDN controller. The reply indicates a plurality of provider edge (PE) devices coupled to a carrier network. The network device employs a processor to cause the transmitter and receiver to establish a plurality of asymmetric connections to a virtual private network (VPN) operating over a wide area network (WAN) via the PE devices.
