Overview: This research paper tells that in last few years, Voice over Internet Protocol (VoIP) has been gaining popularity as an alternative to traditional telephone by transmitting voice signals as packets over the Internet and private IP-based networks. However, voice packets experience loss, delay, and delay variation, which require buffering, playout scheduling and loss concealment at the receiver. This paper gives an overview of a VoIP application and show how playout scheduling and loss concealment are jointly used to optimize perceived speech quality. The paper uses this optimization criterion to design a histogram-based playout scheduling algorithm.
