Abstract
Embedding a flow handle (FH) in an IPv6 address portion of a packet may reduce the amount of overhead needed to support path selection in flow-based packet forwarding. The FH may replace an interface identifier in a standard IPv6 address such that the FH does not add any additional overhead to the IPv6 packet itself. Information specified by the FH embedded in the IPv6 address may be used to select the path or next-hop. In addition, the FH may identify a quality of service (QoS) requirement associated with the packet, and the route selection function may identify a path capable of satisfying the QoS requirement, a service function chain (SFC) ID, an access point (AP) ID, a radio bearer ID, a path ID, and/or a device ID.
