1.  Introduction

   As the development of 5G and new emerging Internet services, such as
   live video streaming, the network are facing a larger and larger SLA
   difference.  For better bearing of the user's traffic, the network
   needs to be intelligent and be aware of the user traffic's demand.
   An innovative method called APN6 is introduced in
   [I-D.li-apn6-problem-statement-usecases] and [I-D.li-apn-framework].

   In the mechanism of APN6, the packet can carry the ID information and
   SLA requirements of the traffic, and the network equipment can get
   them in each packet and handle the packet accordingly.  It is one
   kind of network programming mechanisms in the data plane.

   As the encapsulation information increases in an APN packet, some
   bandwidth is kindly wasted in APN6 which contains a larger overhead
   in every packet.  On one aspect, it is believed that it is necessary
   for the evolution to an intelligent network; on the other aspect, it
   is recommended that after the network has known the requirements of
   the traffic and associated it with a proper policy, the traffic needs
   not to resend the same information in every packet again and again.
   This document mainly describes the process of the later.
