A study on the delay of streaming packets during IP handover between heterogeneous networks

In this paper, the delay time of streaming packets was compared with the delay time of 1500 byte test packets during IP handover between heterogeneous networks, and the deployment of equipment and network for this experiment was performed through the BcN 3^rd phase project, which was hosted by KCC(Korea Communications Commission), and conducted by NIA(National Information Society Agency) from 2008 to 2010. By comparing with the delay time during IP handover between the 1500 byte test packets which were transmitted by every 30 [ms] from a server and the streaming packets of VOD and real time streaming video which were transmitted from a platform for the trial service of Mobile IPTV in commercial network, we can find out the time differences in a test and real situation, and may define an appropriate service suitable for the delay time. A smart phone was used as a test terminal for 1500 byte test packets during IP handover in 2009, and also for the trial service of Mobile IPTV in 2010.
