Eat own dogfood. Many IETF people are developers or work for companies having applications not working. As I said there were a minimum of applications that didn't work. Corporate VPNs largely did. Jen has the final numbers. [...] >>> Advanced features have been also specified, e.g., >>> - if you want to allow for incoming connections: e.g., access a video >> server >>> - if you want to avoid overloading NAT64 with all sorts of ALGs >>> - if you want to avoid draining the battery of your mobile because of >> the keepalive messages >> >> Yep, but I think the cat is largely out of the bag here, and an >> application must work in the "smallest common denominator" network. > > [Med] More concretely? - ALGs do more harm than gain. Applications have been forced to deal with NAT traversal. As in ICE/STUN/TURN. Applications must work with any NAT also those without ALGs. ALGs are dead. - For the applications that need the keepalive wouldn't they send traffic anyway, so that it wouldn't be an additional battery drain. Example of application that doesn't? - Incoming connections? Didn't think we did that on the Internet anymore? :-( That's static configuration in one case, and for the other symmetric hole punching (as in the ICE/STUN case). Would PCP have helped, yes, possibly, but given that applications must work without it anyway... Cheers, Ole
