Hi Folks,
According to the feedback, we updates the draft. The updates are as follows:
1. For home broadband scenario, the figure is changed. The RG is connected to AN (access network), then the metro network. 
2. For mobile broadband scenario, since the scope the APN attribute is encapsulated with the GTP-u tunnel is not in IETF, we remove the part. And the figure is also changed. The APN domain is confined to the mobile transport network.

Accordingly the following draft is also updated.
https://www.ietf.org/archive/id/draft-peng-apn-security-privacy-consideration-02.txt

We updated the drafts according to the apparent issues. We will go on to refine the draft. Your comments are always welcome.

Best Regards,
Robin

Abstract:
   Network operators are facing the challenge of providing better
   network services for users.  As the ever-developing 5G and industrial
   verticals evolve, more and more services that have diverse network
   requirements such as ultra-low latency and high reliability are
   emerging, and therefore differentiated service treatment is desired
   by users.  On the other hand, as network technologies such as
   Hierarchical QoS (H-QoS), SR Policy, and Network Slicing keep
   evolving, the network has the capability to provide more fine-
   granularity differentiated services.  However, network operators are
   typically unware of the applications that are traversing their
   network infrastructure, which means that not very effective
   differentiated service treatment can be provided to the traffic
   flows.  As network technologies evolve including deployments of IPv6,
   SRv6, Segment Routing over MPLS dataplane, the programmability
   provided by IPv6 and Segment Routing can be augmented by conveying
   application related information into the network satifying the fine-
   granularity requirements.

   This document analyzes the existing problems caused by lack of
   service awareness, and outlines various use cases that could benefit
   from an Application-aware Networking (APN) framework.
