Phil,
In my view, ICE _is_ a "Hole Punching Technique".
Yes, you absolutely right, though the devil is in the details.
We cannot go here into a shoot-out between hole punching or other
mentioned on the list vs. ICE, but there seems to be a huge difference
in effectiveness and performance.
What precise algorithm are you talking about when you say this?
As far as I am concerned, ICE is simply a well-documented hole
punching algorithm.
It differs from others that I have seen written up in the following
ways:
- ICE has the concept of peer reflexive addresses, which other hole-
punching techniques that I have seen do not;
- ICE has the concept of controlling/controlled endpoint, which gives
the controller additional flexibility in choosing a path;
- ICE does NOT have the concept of port prediction, which some other
techniques do (e.g., Saikat's TCP work).
