## AI overview

This introductory post explains SPDY, a binary, frame-oriented protocol designed as a replacement or wrapper around HTTP. It describes SPDY as typically running over TLS and using multiplexing to carry many transactions over one TLS connection, reducing the number of TCP connections used for web content.

## Source excerpt

I blogged an introduction to and explanation of SPDY, the next-gen HTTP. It should cover all the basics. SPDY (pronounced speedy) is a replacement for HTTP, and feels like a wrapper for it. SPDY is a packet (frame) oriented binary protocol, usually wrapped in TLS (SSL), and as such a little harder to follow than HTTP. Our care free days in the jungle, surviving on the bare necessities and debugging connections with telnet, are coming to an end.
