Software defined networking (SDN) for campus networks, WAN, and datacenter

As the demand for internet and cloud services continues to grow, enterprise network infrastructures are becoming complex to manage. Methods of deployment and management of traditional network devices can become cumbersome and error prone as infrastructure complexity increases. Thus, the need for an easier but highly effective and secured networking approach to confront the growing demands of network environments is necessary. In recent years, software defined networking (SDN) became an effective way that supports the future of networking especially with the introduction of virtualization and cloud computing. The adoption of SDN concepts across different organizations, offers advantages resulting in the reduction of operational cost using simplified software, hardware, and management method. This paper reviews some of the current SDN solutions developed for campus networks, wide area networks (WANs) and datacenters identified by the Gartner Peer Insights reviews. A survey was also conducted to find out how these solutions have been adapted in different organizations.
