Performance Evaluation of IPTV Multicast Service Testing for XGS-PON Optical Line Termination

Video services on Passive Optical Networks (PON) are widely used for the IPTV multicast services and proliferating. One of the new PON technologies used by telecommunication operators in Indonesia is the 10-Gigabit-capable symmetric passive optical network (XGS-PON). However, there is no technical standardization related to multicast services on the XGS-PON system. Therefore, this study will develop a test method and evaluate multicast services' performance on Optical Line Termination (OLT) equipment of XGS-PON. The OLT has the most critical function in managing services, including distributing Internet Protocol Television (IPTV) service to customers. Six parameters proposed as standardization regulation to determine the XGS-PON OLT capability are as follows: IGMP version 2, IGMP version 3, IGMP Proxy, IGMP transparent snooping, IGMP snooping with proxy reporting, and IGMP Multicast Group. The experiment result confirmed that XGS-PON OLT supports multicast protocols following ITU-T G.9807.1 recommendations, namely IGMP version 2 and IGMP version 3. It also shows that XGS-PON OLT supports IGMP mode capabilities such as IGMP proxy mode, IGMP transparent snooping mode, and IGMP snooping with proxy reporting. Furthermore, XGS-PON OLT supports the maximum number of multicast groups simultaneously for 2048 IGMP multicast groups following the TR-101 guideline from Broadband Forum. These results can be used as a reference for technical standardization regulations development of IPTV multicast service in XGS-PON.
