Webinar details

TCP and HTTP, the transport and presentation-layer protocols used by almost all web-based applications, could have significant impact on web application responsiveness and page load time.

This webinar documents the characteristics of TCP and HTTP, and describes SPDY, a novel protocol that is currently the basis for HTTP 2.0.

Target Audience

If you’re involved with web application development, deployment or operation, or have to plan or design underlying networking infrastructure, you simply have to attend this webinar.


The Problem: This section describes typical modern web application behavior, numerous HTTP requests hidden behind the scenes, and the impact of page load time on perceived application responsiveness.

TCP and HTTP 101 section focuses on TCP and HTTP characteristics that cause delays in web page load process, including 3-way TCP session establishment handshake, TCP slow start, and request-response nature of HTTP.

TCP and HTTP improvements section describes mechanisms used by web browsers (parallel TCP sessions) and servers (increased initial congestion window) to alleviate TCP drawbacks, as well as speedup mechanisms of HTTP (persistent sessions and pipelining).

SPDY: the last section of the webinar introduces SPDY, Google’s new session-layer protocol. SPDY is already available on popular web servers and browsers, and used by some high-volume web sites. It has also been adopted by IETF for use in next-generation HTTP standardization efforts.
