A Research on the Performance Analysis of SPDY Protocol in Mobile Networks

Abstract

SPDY is the new protocol proposed by Google to complement problems of HTTP(Hypertext Transfer Protocol)/1.1 and to improve web speed. In this paper, we evaluated the performance of SPDY protocol in a variety environment. By this evaluation, we examined the characteristics of the SPDY protocol and compared the differences between the existing protocol and SPDY protocol. And we took a closer look at the Flow Control of SPDY. Through this, we analyzed the problem of SPDY. It improved performance at 3G network environment, but failed to improve performance at high speed WLAN and mobility environments. We also verified that Flow Control does not work

Web optimization of QUIC under wireless network

“…In fact, these problems have been identified and improvements have been made, like SCTP, SPDY and HTTP 2.0 (similar to SPDY), etc. [6] [7], but each method has its own shortcomings. The problem with SCTP is that it is a transport layer protocol that requires modification of the protocol stack of the operating systems.…”
