IPv6 again and SPDY

Saturday, June 16th, 2012

It’s now about a year after my previous post about World IPv6 Day 2011 and the same event in 2012 was just a little while ago.

This year’s event was different in that major sites are keeping their IPv6 connectivity online for good (rather than testing it out for a short time like last year).

This time, Google’s IPv6 traffic has doubled from 0.3% to 0.6%. If you have a look at the graph, you can see the huge uptick in the last year. I suspect we’ll see year-on-year doubling (or better) from here on, which would mean every will be using it by about 2020 (hopefully much earlier).

A technology that lights up similar pleasure regions of my brain is the SPDY protocol. It’s basically an optimisation layer that sits above HTTP and aims to  transfer web page resources in a smarter way to reduce page load times.

I’ve installed it on this blog to see how easy it would be. Turns out it was very easy, although I did have to switch the way I serve PHP (from mod_php to fastgci). At the moment only Chrome and Firefox support it on the client side. This protocol addresses an obvious and annoying shortcoming of practical HTTP, so I’m hoping it will take off too.
