The increase in the growth of an Internet increases the voice transmission that degrades the quality of real time voice communication due to packet overhead, network congestion and improper queuing in an IP network. These overheads affect the overall network performance and Qos parameters of voice communication such as packet loss, packet delay and packet latency or jitter. In our study, we have discussed how the active networking services are suited to reduce the impact of congestion in an IP network. An analysis of how the TCP Friendly Equation Rate Control based Cryptographic Active Voice Transcoding (CAVT-ER) Congestion Control mechanism should adapts the throughput generated by the voice packets in response to congestion while maintaining a steady voice data throughput in order to achieve effective QoS of VoIP applications where a smooth sending rate is of importance. We discuss the analytical results of the CAVT-ER performance. As a case study we show that our proposed algorithm would directly control congestion in the network and indirectly lead to fast bandwidth adaptation and minimize packet loss, packet delay and jitter.
