Voice quality evaluation of IP-based voice stream multiplexing schemes

IP-based networks for corporate and public network have been growing widely along with remarkable advances in the devices making up the IP-based network infrastructure. A great deal of attention is being focused on using VoIP (voice over IP) for a wide range of real-time streaming IP services and the VoIP traffic to be a promising traffic over IP-based networks. This paper describes schemes for efficiently transporting voice signals over IP-based networks in order to provide VoIP services. While taking the requirements for these schemes into account, this paper provides IP-based circuit-multiplexing techniques for carrying voices calls over IP-based networks and evaluates the voice quality of those schemes.
