DietTopp: A first implementation and evaluation of a simplified bandwidth measurement method

TL;DR

DietTopp is a new, simplified active bandwidth measurement tool that accurately estimates available bandwidth and link capacity quickly, improving upon existing methods like Pathload and Pathrate.

Contribution

This paper introduces DietTopp, a simplified bandwidth measurement method, along with its implementation and initial evaluation demonstrating its effectiveness.

Findings

DietTopp provides fast bandwidth estimations.

It achieves comparable accuracy to state-of-the-art tools.

It effectively estimates both available bandwidth and link capacity.

Abstract

This paper describes the active available bandwidth measurement tool DietTopp. It measures the available bandwidth and the link capacity on an end-to-end path having one bottleneck link. DietTopp is based on a simplified TOPP method. This paper describe and motivate the simplifications and assumptions made to TOPP. Further, the paper describes some of the DietTopp implementation issues. A first evaluation of DietTopp in a testbed scenario is made. Within this evaluation the performance and measurement accuracy of DietTopp is compared to the state-of-the-art tools Pathload and Pathrate. We show that DietTopp gives fast and accurate estimations of both the available bandwidth and the link capacity of the bottleneck link.
