Abstract
The Internet is huge, complex, and rapidly evolving. Understanding how
today's Internet-scale systems work is challenging, but crucial when
designing the networks and applications of tomorrow. In this talk, I
will describe how I have used a combination of measurement, modeling,
and analysis to understand two Internet-scale systems: (1) peer-to-peer
(P2P) file-sharing systems and their workloads, and (2) indirection
routing systems that recover from Internet path failures.
In part because of the rise in popularity of P2P systems, multimedia
workloads have become the dominant source of Internet traffic. Our
measurements show that multimedia workloads are substantially different
from traditional Web workloads. Based on an analysis of a 6-month long
trace of the Kazaa P2P system, I will propose a new model for
multimedia workloads and will use it to explain how a few, simple,
fundamental factors drive them.
