WG, The submitted version is not yet addressing all the issues raised during IESG review. This is testing the proposed direction without overworking the details. Thus one thing this document definitely needs to be improved at is the following:
- Security consideration comments raised - The analysis of the impact on the inner traffic with UDP tunnels. - Clear how the requirements are or can be meet with the general class of UDP tunnel using protocols carrying IP or transport protocol.
