Performance evaluation of channel zapping protocol in broadcasting services over hybrid WDM-PON

Among several kinds of high-speed access network technologies, wavelength-division-multiplexing passive optical network (WDM-PON) is the most suitable for the increasing bandwidth requirements in the future. In this paper, we propose overlay WDM-PON which uses multicast and virtual local area network (VLAN) technologies for the integration of services such as Internet surfing, voice-over Internet protocol (VoIP) and video on demand (VoD). In addition, shared channel based performance evaluations demonstrate operations and advantages of overlay WDM-PON using OPNET
