Quality of service (QoS) in a narrowband secure voice over data over IP (SVoIP) system is impacted by changes in network behavior, particularly packet loss. Several methods exist for mitigating these effects. This paper analyzes the performance of packet loss concealment using forward error correction, frame replication, adaptive playout buffering, and dynamic buffer selection in a SVoIP system. These methods are shown to improve to varying degrees overall QoS.
