Why each option
Among the listed SDN controllers, OpenDaylight and OpenContrail are the two open-source projects, while the others are proprietary vendor solutions.
Big Cloud Fabric is a proprietary commercial SDN solution from Big Switch Networks, not an open-source project.
OpenDaylight is a Linux Foundation-hosted open-source SDN controller project that provides a modular, extensible platform for network programmability and is freely available under an open-source license.
Virtual Application Networks SDN Controller is HP's proprietary SDN controller product, not an open-source solution.
Application Policy Infrastructure Controller (APIC) is Cisco's proprietary SDN controller for its ACI fabric architecture, not open-source.
OpenContrail (now Tungsten Fabric) is an open-source SDN controller originally developed by Juniper Networks and released under the Apache 2.0 license, making it freely available to the community.
