Augments. We cannot remove UDP since there is too much deployment. And TCP is 
not always needed. And there is startup latency with the 3 way TCP handshake. 
This will slow mobile handoffs. 

I also brought up at the WG that we should consider other transport layers that 
are more secure than TCP by itself. Since your draft doesn’t spec how to use 
TLS with TCP, QUIC may be a more lightweight, efficient and secure alternative.

You can eliminate the periodic overhead by sending Map-Registers less often and 
solicited Map-Notifies as acks. And you can test for map-server reachability 
with RLOC-probes. 

The only reason I bring this up is to disclose that we have existing mechanisms 
to provide reliability. 

And rather than have a completely new message parsing format, we could make 
this proposal simpler by using existing messages that are sent over ANY 
transport.  I have made this comment before. 

Note we did this in the PIM WG where existing messages are sent over TCP or 
SCTP.
