GOOGLE AIM FOR FASTER INTERNET WITH NEW PROTOCOL CALLED SPDY

New Google Internet protocol to replace existing http protocol.

 

Google claim the web pages will be much faster with the new Google protocol called sdpy.

You may not notice is, but in your web browser there is always a http:// in front of all your web pages. Sometimes even a https://.

As long as http has existed, this protocol has been the only way to communicate over the internet.

Google has come up with an alternative protocol, called spdy, which is short for speedy.

In the lab environment the Google developers have created a web server and a Chrome based client. This client runs in a simulated home environment were 25 of the most visited websites in the world is surfed.

Spdy has been up to 64% faster than http to download the web pages in this environment.

Google wish to point out that they are at an early stage of the project and the next step will be to test the new protocol in a real environment.

The main reason for the improvement is the way the new protocol prioritize the traffic, better compression and ability to have several data streams in the same connection.

Sdpy:// will not replace http:// in short term, but Google has told the press that they want sdpy protocol to be a supplement to the http protocol existing today no the internet.

Google wants to improve the performance of using an alternative to the HTTP (Hypertext Transfer Protocol) by minimizing latency. For the new protocol to work, the browser and the web server have to be upgraded, but there will be no need to change the Web pages themselves.

Google’s lab tests of SPDY show an improvement in page load times compared to HTTP of between 27 percent and 60 percent, and between 39 percent and 55 percent when using SSL (Secure Sockets Layer).

SPDY uses a number of techniques to speed Web downloads, including allowing many concurrent HTTP requests across a single TCP session, prioritizing the requests, and using compression to reduce the number of packets and overall amount of data sent.

Google doesn’t want to start from scratch with SPDY. The protocol still uses HTTP headers, but it overrides other parts of the protocol, such as connection management and data transfer formats.

Experts states that Google is trying to improve download speeds, and the numbers are very promising, however for SPDY to work, everyone has to be on board. The protocol won’t become a success unless it’s supported in both Internet Explorer and Firefox. It might be able to convince Mozilla to implement the protocol in Firefox, but convincing Microsoft will be difficult. However, it can also be a competitive edge for browsers that wants to take over market shares from Microsoft and others.

Google has made the source code for the prototype Google Chrome browser available for download and tells that the code for the server will be released as open source in the near future.

The fact that Google is opening up the code is good, but it also needs to approach standards organization IETF (Internet Engineering Task Force).

Development efforts on other protocols to speed Web downloads, such as SCTP (Stream Control Transmission Protocol) and SST (Structured Stream Transport) have seen little activity in recent years.
