QW2002 Paper W1 Eric Siegel (Keynote Systems) Introduction to Performance on the Internet and Web

Key Points

• The main factors contributing to performance and availability on the Web and Internet
• Covers relevant Web and Internet protocols (TCP, IP, HTTP, SSL, DNS)
• Covers peering, routing ; server-room connectivity; caching; CDNs

Presentation Abstract

This tutorial provides a thorough grounding in Web and Internet technologies that affect performance and availability. It explains the fundamentals of Internet performance engineering, which is not just a matter of bandwidth! We'll cover both the protocols and the Internet and Web architectures, but only those pieces that are relevant to performance. It concentrates on the differences between the protocols used on legacy networks (e.g., SNA) and those of the Internet (TCP/IP, DNS, HTTP), along with the differences between a private network based on owned links (leased lines, frame relay, etc.) and a network based on the Internet (Internet routing protocols, connection points between networks owned by different organizations, internal caching, load distribution technologies, etc.) If you're new to the problem of assuring quality over the Internet, come to this tutorial to gain a solid foundation in the relevant technologies.
