To quote from Page 28 of the Advanced Network Architecture document: http://www.morst.govt.nz/uploadedfiles/Documents/Current%20work/An%20Adv anced%20Network%20Architecture%20for%20New%20Zealand%20V1.11.pdf "...Beyond the current use of the Internet for email, web-browsing and web-oriented applications, some of the current R+E+I use is to support applications that require peer-to-peer connection between institutions, both nationally and overseas, simply because there is no other economic alternative. For this last important group of applications the overall Internet performance is particularly bad - latency, jitter, low bandwidth and packet loss are aggravated by the volume-oriented cost structures. ..." Is it just me, or is that a nice little dig at the current Internet situation and it's duopoly on International bandwidth (OK, so the likes of IHUG and others have their "own" International links, but they probably pale in comparison to the big two.) Oh and I see that it's primarily IPv4 based, with IPv6 being offered as a service over the top. So much for next generation... Shouldn't this be IPv6 based from the start, with perhaps IPv4 gateways at the fringe? Maybe I just need to read more... But it's home time... Later'ish Craig
