Abstract

This document describes enhacements which were made to Nevot to provide resiliency to packet loss. Nevot is a multiparty voice conferencing tool for the Internet. It provides a Tcl/Tk user interface, and supports a variety of different codecs and general options. The enhancements use an exclusive or mechanism to provide a RAID style redundancy to packets. A dynamic receiver mechanism was constructed to vary the delay introduced by the system based on network loss. The redundancy parameters are controlled through a new panel in the user interface.
