Metro optical Ethernet technologies with modified OAM&P features

Ethernet is the technology mainly used for the local area network (LAN). Enhancements in Ethernet has been adopted which will lead towards the carrier-grade features and this can be used in the metropolitan area networks (MANs), which can also be adoptable to the typical OADM metronetwork. Dropping and supervisory channel of OADM Network are selected based on the parameters of bit error rate, optical signal-to-noise ratio (OSNR) and optical power. The role of ROADM in Ethernet metro ring network has been analyzed by using an algorithm, which is used for selecting dropping channel, control and link failure detection purpose on the software basis.
