摘要：A major consideration with the NGN is that it provides an equivalent voice service quality and resiliency as the current telephone network. The analysis carried out for this paper looked that without making any real time arrangement in data network in case of IP network will definitely detorate the Quality of service. So arrangement of Real time is mandatory for network quality and QOS of voice. In case of VOIP it is simply a transmission of voice packets over layer 3 i.e. Network Layer .No fix quality measures has been taken so far to achieve the quality in VOIP. By using the RTP& RTCP as a Application Layer Signaling Control Protocol in NGN network will ensure the bare minimum packet loss(pay load) for telephony. The scope of this paper will prove that real time application i.e. voice transmission if it sent over non real time network with RTP/RTCP(Application Layer Signaling Control Protocol) the quality increases & provides an equivalent voice service quality and resiliency as the current telephone network.
