dc.description.abstractThere has been many changes in the network service providers that engages the routers, switches and many other complex protocols, but the current computing trends don’t want to change the network as a whole as of optical networks. In the market of current network trends, data eccentric nodes has been a part of them and these nodes requires high speed as of now, to meet the high speed demands the circuit switching part has been merged with the packet switching part which can modify the network as a whole. The high speed of the network is managed by the circuit switching while error free delivery of packets from the transmitter section to the receiver section has been managed by the Packet Switching. Circuit switching is being used in the Optical Networks because nothing can overpower the speed of the light and they travel by the speed of light. Only Packet Switched network won’t make any difference there is a need to make the system programmable, adaptable and flexible according to the current computing trends since there is a need of the networks to adjust according to the heavy traffic demands since in different networks there is a different traffic demand in the data eccentric nodes. The nodes should travel by itself to forward and route the packet according to the path when it is idle and should move through the conventional path when it’s congested. This routing of packets could be done through OpenFlow Switches following the OpenFlow Protocols. The communication system which are used conventionally consists of large number of switches, middle boxes and routers for the communication part, they basically lack in the programmability of the network. SDN is different from these conventional communication systems as it separates the forwarding plane with the control plane. Switches used here are also different from the conventional as they follow a significant protocol which is basically an Open Flow Protocol. In the project, the Optical part of Software Defined Networks (SDN) has been designed through the Optisystem Software version 19.0. Optical switch using Reconfigurable Optical Add Drop Multiplexer (ROADM) have been designed in the software. The data is provided to the user through Optical switches present in the ROADM, the data could be a binary bit or a binary sequence depending upon the needs and requirements of the user. 6 The system consists of the CW Array which consists of total 8 numbers of users at different frequencies that are 193.1Thz, 193.2Thz, 193.3Thz, 193.4Thz, 193.5Thz, 193.6Thz, 193.7Thz and 193.8Thz. Another set of CW Array and multiplexer is also present where the data is sent through the fork to the subsystem designed of ROADM. It consists of WDM Drop, Control, Optical Switches and WDM Add. The signals of different frequencies are provided to the subsystem. The results are recorded in both time and frequency domain at different signals provided and from the obtained results it can be concluded that the received data is same as that of transmitted data. SDN provides provision to the users to be independent of the network operators as the users don’t have to change the network as a whole with the changing trends of computing demands just have to reprogram the network.en_US
