Performance of QOS parameters for IPTV through NGN

This paper describes in details the IPTV (Internet Protocol Television) system. Also, measurement methods of the QoS parameters are analyzed, debating a practical application for evaluation of IPTV traffic parameters. QoS (Quality of Service) parameters such as IP Packet Transfer Delay (IPTD), IP Packet Delay Variation (IPDV) and packet loss Ratio (IPLR). The recent Internet is working under TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack and is based on two main fundamentals, which are: network offers only one class of service named best effort service, and network resources are overprovisioned as possible in order to minimize packet losses and packet delays. The Internet providers aim to provide packet transfer to users as fast as possible, However they are far from guaranteeing, so called, rigid quality of service (QoS) that is measured by the maximum allowable values of such parameters as IPTD, IPDV and IPLR. Furthermore, network abilities of packet transfer determine the range of applications which users may use with appropriate satisfaction these applications such as IPTV. ANYLOGIC Professional6 software was used to analysis the QoS parameters for IPTV and our results help in critically analyzing QOS parameters for IPTV applications.
