Top 10 SDN Consulting/Service Companies - 2020
A discussion of technology always has inherent value, particularly from an educational perspective. But from a practical standpoint, the reason technology exists is to deliver functional benefits. In Software Defined Networking (SDN), that value primarily derives from what the applications can do. Therefore no discussion of SDN is complete without considering the specific benefits of applications. One common application will be path computation or end-to-end provisioning. Over the years, many methods have sought to provide a Path Computation Element (PCE). One attempt was to embed the PCE into the Network Element (NE). In fact, this idea is the opposite concept from SDN because it mingles the control and data layers. From a practical standpoint, merging these two layers has several limitations. One is that, because the hardware on the NEs is limited, the scale of the domain this hardware manages is also limited. SDN overcomes this issue by the very nature of the hardware it runs on, specifically a server.
Furthermore, SDN can create a programmable network by taking both next-generation systems and existing infrastructure and making them substantially more dynamic. It does this by bringing disparate systems and technologies together under a common management system to utilize them to their full potential. By using abstraction, SDN can simplify the software needed to deliver services, improving the use of the network and shortening delivery times, leading to increased revenue.
