Re: [RRG] Why delaying initial packets matters

It likely would be helpful if proposals would clearly document which
problems they are solving and also which they are not solving.

If this is a comment against LISP, the lisp-alt draft indicates that a Data Probe or a Map-Request can be sent over the LAT topology. So if you don't mind drops, the Map-Request is sent to trigger a Map-Reply. If you don't want any packet loss (dropped intentionally at the ITR), then the Data Probe is used to solicit the Map-Reply.

So we don't state the problem, we state the solution. Is that not sufficient?
