A Review on Issues, Challenges, and Solutions of Scalability and Optimization Problems in Software Defined Networks
The time has come, when; Software Defined Networking (SDN) will be an essential service in the world for those who are using a large network in their organization. To improve the traditional network; SDN/open Flow Protocol will play a major role. Presently open flow protocol is not supported by all southbound hardware devices. Most of the organization depends on single-vendor support. But it seems the scope of open flow protocol will be strong. The monopoly of the single-vendor support will be overcome, once every OEM of network device gives the priority to the open flow protocol implementation in the network devices, and then SDN will become a powerful tool in the networking field. Software defined network divides the network into three planes; control plane, data plane, and management plane. In this paper, we present scalability and optimization issues, challenges, and their solutions as well. Also, cover the issue and solution faced while implementing the SDN in the traditional network.
