Improving service quality in IPTV networks

Abstract: Technical advances in recent years allow to transfer video over IP networks with acceptable quality. One of the main difficulties in providing services over IP networks is packet loss at the moments of mass channel switching and, as a result, deterioration in the quality of transmitted information. The research objective is improving the quality of service in IPTV networks, reliability of communication area due to the use of a redundant switching field with parallel configuration in IP switches, which provides load dividing for normal operation and avoids collapsing network under peak traffic. The block diagram and operation algorithm are given, which allows to increase the processing speed of the IPTV head station. Specific feature of load distribution is described by the fact that servicing one data flow can be provided by different information fields at different stages. There has been given a formalized model of parallel block switch. Today, modern switching systems do not allow tuning by parallel methods and combining the transfer of information with system tuning.
Keywords: IP networks, switch, commutation field, parallel search, parallel identifier, data flow, parallel structure.
