Abstract
A method for steering an original packet transmitted by a UE. The method includes receiving a first packet, wherein the first packet encapsulates the original packet. The method also includes extracting networking information (e.g., IP source, IP destination, tunnel identifier) from the first packet. The method also includes generating an SFC header (e.g., an NSH header), wherein the SFC header comprises: i) an SPI that identifies a service path and ii) metadata, wherein the metadata comprises the networking information extracted from the first packet. The method also includes generating a second packet comprising the SFC header and the original packet. The method also includes providing the second packet to an SFF that is configured to select a service path based on the SPI included in the SFC header of the second packet and forward the second packet based on the selected service path.
