Abstract(in English) This paper proposes to use UDP and UTP (Over IP) with Feedback controlled Redundant Packet Insertion Algorithm to minimize the packet losses in Real-Time communications over the Internet, where the redundant data about present packets are piggybacked along with later packets. The redundant packets are encoded at a lower rate (secondary encoding rate) compared to the primary encoding. With the increase of number of redundancies the QoS and reliability will increase, but it is inefficient with respect to the bandwidth. Therefore the proposed control algorithm inserts redundant blocks based on the feed back from the network by varying the Combination Value (CV) suitably. CV is defined such that number of redundant packets inserted is increased with the CV The QoS improvement due to the proposal is proved mathematically using simple M/M/l/K queue to model the loss process in the network and also by simulation. This control algorithm is proposed with the aim of controlling packet losses within the limits of High and Low depending on the application.
