Re: [OPSAWG] I-D Action: draft-ietf-opsawg-capwap-alt-tunnel-10.txt

Hi, Everyone,

	We have submitted a new version for the "Alternate Tunnel Encapsulation for Data Frames in CAPWAP".

	It has been changed to an Experimental draft, and we have added a new section to introduce the History of the document.

1.3.  History of the document

   This document was started to accommodate Service Provider's need of a
   more flexible deployment mode with alternative tunnels [RFC7494].
   Experiments and tests have been done for this alt-tunnel network
   infrastructure.  However important, the deployment of relevant
   technology is yet to complete.  This experimental document is
   intended to serve as a historical reference for any future work as to
   the operational and deployment requirements.

	Welcome for comments. If no objection, please trigger the last call.

	This draft has gone through a last call last year. 
	After that, we have changed it according to the comments collected.

Best Regards
Zongpeng Du

Abstract:
   Control and Provisioning of Wireless Access Points (CAPWAP) defines a
   specification to encapsulate a station's data frames between the
   Wireless Transmission Point (WTP) and Access Controller (AC).
   Specifically, the station's IEEE 802.11 data frames can be either
   locally bridged or tunneled to the AC.  When tunneled, a CAPWAP data
   channel is used for tunneling.  In many deployments encapsulating
   data frames to an entity other than the AC (for example to an Access
   Router (AR)) is desirable.  Furthermore, it may also be desirable to
   use different tunnel encapsulation modes between the WTP and the
   Access Router.  This document defines extension to CAPWAP protocol
   for supporting this capability and refers to it as alternate tunnel
   encapsulation.  The alternate tunnel encapsulation allows 1) the WTP
   to tunnel non-management data frames to an endpoint different from
   the AC and 2) the WTP to tunnel using one of many known encapsulation
   types such as IP-IP, IP-GRE, CAPWAP.  The WTP may advertise support
   for alternate tunnel encapsulation during the discovery and join
   process and AC may select one of the supported alternate tunnel
   encapsulation types while configuring the WTP.
