Hi Aabid
Regarding your query i would say that this network on which i am working would provide the following advantages in comparison to optical network or ethernet network individually.
1) since we have nowadays data centric nodes so for that good speed is provided by the optical part of my network but in addition to it we would require error free recovery of messages and that is provided by ethernet part.
2) Coming to resource optimization , since in any ordinary network we would just program our nodes to route the packets through a definite path but when we have SDN at our disposal we can reroute the traffic in accordance to the demand and less conjusted path and make use of those nodes which would have stayed idle if the conventional path was followed.
3) It also helps in cost reduction of networks as in ordinary networks if we want our traffic to follow a new path we have to install all the infrastructure all over again, but when we add SDN to our optical networks we can program the existing networks.
I hope you got the idea about the advantages of SDON( Software Defined Optical Networks).
Best Regards
Burhan
