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 between two different kinds of traffic.  For better
   bearing of the user's traffic, the network needs to be intelligent
   and be aware of the user traffic's demand.  An innovation 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 encapsulation information increases in an APN packet, some
   bandwidth is kindly wasted in APN6 which uses a larger overhead in
   every packet.  On one aspect, it is believed that it is necessary for
   the evolution to the 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 talks about the process of the later.
