Mike’s Lookout – SPDY of the Future Might Blow Your Mind Today

Despite its coolness, there is an aspect of SPDY that doesn’t get much press yet (because nobody is doing it). Kudos for Amazon’s Kindle Fire for inspiring me to write about it. I spent a fair amount of time running network traces of the Kindle Fire, and I honestly don’t know quite what they’re doing yet. I hope to learn more about it soon. But based on what I’ve seen so far, it’s clear to me that they’re taking SPDY far beyond where Chrome or Firefox can.

The big drawback of the previous picture of SPDY is that it requires sites to individually switch to SPDY. This is advantageous from a migration point of view, but it means it will take a long time to roll out everywhere. But, if you’re willing to use a SPDY gateway for all of your traffic, a new door opens. Could mobile operators and carriers do this today? You bet!

Check out the next picture of a SPDY browser with a SPDY gateway. Because SPDY can multiplex many connections, the browser can now put literally EVERY request onto a single SPDY connection. Now, any time the browser needs to fetch a request, it can send the request right away, without needing to do a DNS lookup, or a TCP handshake, or even an SSL handshake. On top of that, every request is secure, not just those that go to SSL sites.
