Hi Shuping,

Would you show a general use case of dissemination of BGP Flow Specification Rules for APN?  Personally I think this will conducive to understanding the new approach and promoting it in the future.

Best regards

Chongfeng

Hi all, 
                                                                                                                                              
We have published this draft on the dissemination of BGP Flow Specification Rules for APN (https://datatracker.ietf.org/doc/html/draft-peng-idr-apn-bgp-flowspec), to enable the traffic filtering in an APN domain as well as the traffic control and actions at the policy enforcement points in this domain. 
 
The technical points of this draft include:
1. A new BGP Flow Spec Component Type is specified with the match field APN ID to support the traffic filtering using APN. 
2. A Grouping Identifier Opaque Extend Community [RFC4360] (Sub-Type = TBD2) carrying both Group ID (2 octets) and Sub-group ID (2 octets) is defined, aiming to provide an efficient grouping mechanism for the multiple co-existing Flow Specification rules to be matched in a desired order as well as the actions being applied to a particular traffic flow. The encoding format, usage principles and usage example (APN) are provided. 
3. Traffic filtering actions (incl. Traffic Marking, Inherit, Stitch) are specified to enable the creation of the APN ID in the outer tunnel encapsulation when matched to the corresponding Flow Spec rules.
 
Your review and comments are appreciated. Thank you!
 
Best Regards, 
Shuping

Abstract:
 
   A BGP Flow Specification is an n-tuple consisting of several matching
   criteria that can be applied to IP traffic.  Application-aware
   Networking (APN) is a framework, where APN data packets convey APN
   attribute including APN ID and/or APN Parameters.  The dynamic Flow
   Spec mechanism for APN is designed for the new applications of
   traffic filtering in an APN domain as well as the traffic control and
   actions at the policy enforcement points in this domain.  These
   applications require coordination among the ASes within a service
   provider.
 
   This document specifies a new BGP Flow Spec Component Type in order
   to support APN traffic filtering.  The match field is the APN ID.  It
   also specifies traffic filtering actions to enable the creation of
   the APN ID in the outer tunnel encapsulation when matched to the
   corresponding Flow Spec rules.
