Full Speed Ahead for the Evolution of the Internet

4G Americas Releases Report Outlining SPDY & HTTP 2.0 Plans and Protocols

BELLEVUE, WA -- (Marketwired) -- 06/23/14 -- 4G Americas, a wireless trade association representing the 3GPP family of technologies, including LTE and LTE-Advanced, today released a new report titled, The Impact of SPDY on the Mobile Broadband Ecosystem and Value-Added Services. The report delivers a clear-cut summary of SPDY's immediate and long-term impacts on the mobile broadband ecosystem and wireless technology architectures.

SPDY, pronounced as "speedy", was initially developed by Google in 2009 as an open networking protocol for transporting web content. SPDY is not a replacement for Hypertext Transfer Protocol (HTTP), but rather a modification of how HTTP requests and responses are transmitted. In 2013, SPDY was supported by Chrome, Firefox, Internet Explorer and Opera, plus many large web platforms (e.g., Google, Twitter and Facebook) which were all offering SPDY to compatible clients.

"The Internet has transformed dramatically over the past decade and there is general recognition that changes are required to improve performance and optimize user experience," commented Kevin Shatzkamer, author and work group leader of the 4G Americas report, and Distinguished Systems Engineer at Cisco. "It is important to continue to evaluate new protocols that progress the Internet itself to support more social, more mobile communication paradigms."

The goals of SPDY are to reduce the load latency of web pages by addressing: 1) some of the performance limitations of HTTP 1.1; the latest version of HTTP, a protocol used by the Worldwide Web to define how messages are formatted and transmitted, and 2) what actions Web servers and browsers should take in response to various commands.

SPDY is specifically aimed at:

  • achieving a 50 percent reduction in Page Load Time (PLT)
  • designing a more efficient use of the underlying Transmission Control Protocol (TCP) connection by introducing a new binary framing layer to enable request and response multiplexing
  • prioritizing to minimize and eliminate unnecessary network latency

As a result, the Internet Engineering Task Force (IETF) HTTP Working Group (httpbis) kicked off the new HTTP 2.0 effort in early 2012 to secure that the lessons learned from SPDY are applied to the next evolutionary step in HTTP -- the HTTP 2.0 standard.

A leading organization in developing and pushing forward the standards which will facilitate SPDY and HTTP 2.0 is the Alliance for Telecommunications Industry Solutions (ATIS) initiative named, Open Web Alliance (OWA). The goals of OWA which are mentioned in the 4G Americas white paper, state that collaboration with the following are needed to support key decisions about Internet architecture: 1) stakeholders to identify requirements and solutions, 2) privacy groups to promote use and education on various aspects of Internet security, and 3) regulatory bodies to realign the current reality of the Internet.

"4G Americas supports the newly formed Open Web Alliance as we feel it will be an important first step for all of the key stakeholders using or affected by SPDY to communicate, collaborate and coordinate solutions," said Chris Pearson, President of 4G Americas.

Kevin Shatzkamer added, "4G Americas recognizes SPDY as one of a multitude of performance and security enhancing protocols designed for today's Internet architecture and values OWA's commitment in bringing multiple stakeholders together to accommodate to the future of the Internet."

The report, The Impact of SPDY on the Mobile Broadband Ecosystem and Value-Added Services, was written collaboratively by members of 4G Americas. This white paper is available for free download at: www.4gamericas.org.
