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intended to serve as a historical reference for any future work as to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.
