Out of order arrival of packets can significantly degrade the performance of many TCP-based, VoIP-based and video-based applications. There is a need for a matric that can meaningfully and accurately characterize reordering.

On these pages we present simple application, which allows to compute the packet reordering metrics from RUDE/CRUDE output files and presents results as statistics and charts.

Application was developed according to definitions included in two IETF internet drafts:
- draft-ietf-ippm-reordering-05.txt
- draft-jayasumana-reorder-density-02.txt

For RUDE/CRUDE description and simple HOW-TO see Rude/Crude section.

The program calculates reordering for first 500 packets of each RUDE/CRUDE packet trace only.

If you want to try it, here is the simple rude/crude output file: RUDE/CRUDE output
