Re: [IPsec] Proposed wording for a revised charter

[Tommy Pauly <[e-mail]>]

I would also like to see the draft for TCP encapsulation added as an item, since we’ve gotten a fair amount of support for it. For the purposes of the charter, it may be good to have a broader explanation of the goal—something to the effect that the working group should focus on making sure that IKEv2 can be deployed more universally by taking into account limitations of various networks. Previous RFCs like IKE fragmentation have contributed to this; TCP encapsulation tries to solve another set of problematic networks; and we can imagine that there may be more to investigate, such as taking into account the limitations and requirements of IoT networks, etc.
