A Study on the Protection of EPON
Koo Bon-Jeong, Jeong Hur, Kim Sunghwi, Cho Seong-Dae, Youngil Park · 2004
Network protection has been mainly applied to trunk network. PTP, ring, linear, mesh topologies of SONET/SDH system and 565 Mbps PDH systems are among those examples. But, as larger capacity PON system is introduced, protection in access network system also becomes necessary. In this paper, an efficient EPON protection scheme utilizing the EPON's frame and protocol is proposed and the implementation results showing protection within 1 msec are provided.
