Paper Abstract:
|
Current tools and methods for measuring packet-based end-to-end network connections are facing two problems. First, no tool or concept covers all characteristics that are necessary to describe such an end-to-end connection. Second, even specialized tools and concepts lack the required accuracy when used in scenarios with network emulators. Therefore, we developed our own cooperative and active network measurement tool called NORA based on existing and well-established concepts and published it as open-source software. Our evaluation shows that NORA covers all relevant network parameters and exceeds existing tools in terms of accuracy, especially when used with network emulation. In this paper we describe the general concepts, implementation and evaluation of NORA, which has the ability to analyze rates relating to bandwidth, packet delay, loss, duplication and reordering in a single measurement for UDP and TCP. |
