Abstract
In this paper, we design MAC protocols for two different SuperPON upgrading architectures using WDM[3], which are considered as future broadband access network. Both protocols are based on the dynamic slot allocation in order to maximize the multiplexing gain of upstream bandwidth. Two different WDM-PON architectures are compared in a view of MAC performance. According to simulation, we can know that architecture-1 (in which wavelength multiplexers are placed at amplified splitter) utilizes upstream bandwidth more flexibly than architecture-2 because it shows stable distribution of transfer delay and less CDV regardless of offered load.
