SANTA CLARA, Calif. -- OpenDaylight Summit -- NFV and cloud are the leading use cases for OpenDaylight, according to a survey of the SDN controller's users released by the OpenDaylight Project Tuesday.
The survey showed that 73% of users have already deployed or plan to deploy OpenDaylight in the next 12 months, with 24% investigating, according to a blog post by OpenDaylight marketing head Melissa Logan and marketing chair Chris Buerger.
Nearly a third of respondents, 31%, were telcos and service providers, with research and academic institutions accounting for 24% and enterprises for 20%. The remainder of respondents were drawn from service and consulting businesses, vendors and other organizations.
Some 72% of users cite NFV as their top use case, with cloud orchestration such as OpenStack at 54%, fulfillment such as traffic engineering and QoS at 47% and network monitoring and analytics at 41%. OpenDaylight's recent Lithium release adds capabilities for all four of these use cases, the blog post notes. (See OpenDaylight Ships 'Lithium,' Updated SDN Controller.)
NFV is expanding beyond telcos to enterprises and academia and research, Logan and Buerger write.
Users are looking to OpenDaylight for software interoperability, operational efficiency and greater innovation and competitiveness, they say.
"What is OpenDayight doing well?" Logan and Buerger write. "Our users were keen to point out that OpenDaylight is widely considered the de facto SDN controller stack, that we remain truly open, and that we have inspired an active community of developers, users and suppliers to participate in our ever-growing open SDN ecosystem." But users say OpenDaylight needs to improve documentation, and OpenDaylight is working on that, the marketing duo note.
