Orchestration and Reconfiguration Control Architecture
—The control mechanisms that are provided today in wireless technologies are not adequate to deal with extreme (ultra‐low latency, ultra‐high throughput, ultra‐high reliability) and diverging (low AND high data rate, time‐critical AND non-time critical) communication needs. Interesting evolutions are happening at different levels that enable the creation of parallel network slices, each slice forming a different network sharing the underlying wireless infrastructure and spectrum. The overall ORCA vision is to drive end-to-end wireless network innovation by bridging real-time Software-Defined Radio and Software-Defined Networking, exploiting maximum flexibility at radio level, medium access level and network level, to meet very diverse application requirements.
