Social networks are making the dream of real time group communication a reality. Voice over Internet Protocol (VoIP)based social network applications are becoming popular but are also suffering from Quality of Service (QoS) and Quality of Experience (QoE) issues. In order to add to its popularity and reliance VoIP based social network implementations should curtail on impairments like Delay, Jitter, Spiky delay, Packet loss and many other. The playout buffer of these VoIP based applications play significant role in maintaining the order and playout timing of voice packets. Many playout buffer algorithms are there that help in adjusting the buffer size and thus coping up with different impairments.
