Magnus,
I've asked for a SECDIR review of last changes to the draft.

The port assignee and contact being the IESG makes sense to me and I will update the draft to reflect this.

The use of two reference RFCs doesn't make sense to me, though, and I don't see any examples of this in the current IANA registry. The TCPCLv4 supersedes v3 and is entity-level interoperable with v3. The RFC-TBA also references RFC7242 internally, so if the IANA port registration of just RFC-TBA will allow someone to trace back to RFC7242 if they need to. Seeing one port with two separate protocol versions in the reference seems confusing.

Hi Brian,

Can you please try to get feedback on the update from the Secdir reviewer, or if
you already have, it provide a pointer to that.

Anyway, looking at the update I did find an issue we need to fix.

In Section 9.1 the Update to the dtn-bundle TCPCL port registration.

As this is an IETF protocol now, the assigne should be:

IESG <[e-mail]>

IESG have had some discussion about the contact person and if that also should
be the IESG, the WG or an individual. The argument for making it to IESG is that
it likely to be more long term stable that the other options. But, this is more
open to discussion, so consider what makes most sense long term and use that.

When it comes to references I think there is a point to list both the RFC-TBA as
well as RFC7242 that defines the earlier version. But, please list RFC7242 after
this docuemnt.

Cheers

Magnus
