Fast management of ONUs based on broadcast control channel for a 10-gigabit-capable passive optical network (XG-PON) system

Youngsuk Lee; Dong Soo Lee; Hark Yoo; Youngsun Kim

This paper proposes a broadcast software download (BSD) scheme for a 10-gigabit-capable passive optical network (XG-PON), which dramatically reduces the time required to update a remotely-located user terminals software. The performance of the proposed BSD is examined by numerical analysis and demonstrated by experimental verification on our XG-PON test platforms. The results show that the BSD takes less than 5 minutes to update 45 user-terminal software, while the conventional unicast software download scheme normally takes more than one and half hours.
