ENDE: an End-to-end Network Delay Emulator

Abstract

The Internet provides a common interface between ographics. different types of computers and networks, and various applications and protocols are constantly being developed. A new protocol or application after being developed has to be tested on the real Internet or simulated on a testbed for debugging and performance evaluation. protocol developer typically requires access to multiple machines across the Internet for this reason. In this thesis we present a new took that can emulate end-to-end delays between two hosts without requiring access to the second host. The tool enables the user to test new protocols realistically on a single machine. The tool observes network status on a particular path using ICMP packets and uses it as a real-time traffic source. Experimented results are presented to show that this approach is effective and quite accurate.
