Introduction: Trends in NV and SDN Controllers
This year, SDxCentral.com has combined the software-defined networking (SDN) Controller and Network Virtualization (NV) report. The reason is that we see the two technologies as complementary – and these markets will likely converge over time. We also see a potential for these solutions to end up merging with orchestration systems such as cloud management platforms or OSS or network service orchestration platforms. Regardless, most of today’s NV platforms contain SDN controllers. Or put another way, NV is the most common use case for SDN controllers.
Generally speaking, NV solutions have mostly been deployed within data centers for cloud platforms (used in both enterprises and service providers), though we have seen NV start their spread into the campus and the WAN with SD-WAN based on overlay technologies. At the same time, SDN controllers (independent of the NV use case) have primarily been used for WAN deployments, to control and built out dynamic WAN topologies, or in other service provider solutions involving service function chaining. We will split out the technologies where we can, and the vendor product section at the end of this report containers separate categories for SDN controllers and NV solutions.
Many networking vendors are investing heavily in both NV and SDN technology, and end users, both on the enterprise and service provider side, tell us they need both. Much of the analysis of this report is based on our user survey which guided our research. The emphasis in this report will be on NV in the data center – though we will discuss how this will evolve into the WAN. Our forthcoming 2016 Virtual Edge report (to be released in October) will focus on WAN applications, especially in the service provider world.
Among the things we will look at include:
