PROJECT TITLE :

Signaling free localization of link and node failures in an optical mesh-tree network

ABSTRACT:

A monitoring mechanism combining the advantages of a monitoring trails scheme and an optical coding scheme is proposed; the mechanism will be employed in a metro-access network. Optical encoders are centrally placed in an optical distribution network and at both sides of every remote node, that makes for a lot of easier installation and smaller management prices. A changed heuristic monitoring trail allocation algorithm is used for monitoring the inner links of the mesh network. The principle of the entire monitoring theme and numerous fault scenes are displayed. The results show that the designed monitoring mechanismcosts less and is easily scalable. This system can monitor not only the states of fiber links however also nodes within the network to alleviate the false alarm likelihood. It can conjointly support high network capability. Moreover, it can take a trade-off of the quantity of monitors and optical encoders.
