WAN emulation has received increasing attention in recent years as
researchers address large, complex and challenging Internet
performance problems. WAN emulation is attractive for such studies as
the emulation environment offers a flexible, reproducible and
realistic environment that enables controlled experimentation with
unmodified end-user applications.
This talk will introduce the Internet Protocol Traffic and Network
Emulator (IP-TNE). Developed at the University of Calgary, IP-TNE
uses a parallel discrete-event simulator kernel which enables high
performance emulation. The primary advantage of IP-TNE over other WAN
emulators is fast execution time, enabling the emulation of
non-trivial networks. A case study on Web server benchmarking is used
to demonstrate the capability of IP-TNE. This study will also discuss
efforts (completed, in-progress, and planned) to validate the
emulator.
