摘要：Protection and restoration mechanisms have been applied in backbone networks, but access networks are not considered significantly in the scope of survivability. In this paper, we propose a cost effective protection scheme for a novel tree-based EPON architecture in distribution region. The protection scheme is capable of fault detection within 2 ms, assuring zero packet loss with the assisting of Access Control System. The Optisystem CAD Software product of Optiwave Inc was used to investigate the system performance and to roof the system feasibility in four failure conditions.
