Project Aspen is the Open Source version of the ONF Real Time Media NBI for the IMTC QoE use case. The original deployment scenario assumptions:
Unified Communications (UC) in Enterprise networks
ONF is specifying an API that allows applications to inform SDN controller
Initially the focus was only on unified communications (e.g. Lync, Webex, Skype); now the scope is extended to real-time media apps in general. A description of the code is provided (Creative Commons license), the reference code has been delivered (Apache 2.0), and the final implementation code is expected shortly (September 2015).
