Here is a brief description of what SPDY is ?
SPDY is an
Experimental Application layer protocol which augments HTTP protocol
with new features and best practices. HTTP and TCP are the standard
protocols used for the web today. There is not much we can optimize
at the transport level (TCP) so the HTTP protocol at the application
layer was rethought. HTTP protocol at the application layer has a lot
of drawbacks. Thus SPDY was designed to overcome these drawbacks of
HTTP and help load the web Pages faster.
SPDY introduces some of
features such as Multiplexing of Streams, Request Prioritization,
Server initiated streams and HTTP Header Compression. It has been
experimentally determined that page loads are 50% faster in SPDY than
in HTTP. There are both client and server level support for SPDY
protocol. SPDY is easier to deploy and is also server efficient. SPDY
with SSL is also implemented for secure transmission of data over
SPDY protocol.
Important goals of SPDY include faster page loads and
improved web security. SPDY
also supports Bidirectional streams. Most of the client end Browsers
such as Firefox, Silk and Chrome now fully support SPDY protocol. At
the server side, Servers such as Apache, Jetty etc. are now
supporting SPDY. Most of Google Web sites now have completely
implemented SPDY protocol.
