Survivability models for radio-over-fiber passive optical networks (RoF-PON)/PON
2011 seventh International Computer Engineering Conference (ICENCO'2011), 2011In this paper, we will propose some models for PON/RoF-PON combines a number of ideas used before in the research papers, the ITU-U recommendations and also a number of novel models. We compare between those proposed models by using the Expected Survivability Function; a simple and intelligent tool to evaluate network survivability.
