The adoption of new Unified Communications and Collaboration (UC&C) solutions (mainly based on video) is crucial for the business development and the strategy success of enterprises widely spread on geographies. Multiple UC&C applications often share the same network resources and are unaware of traffic generated by other services in terms of effective bandwidth usage.
Moreover, the traditional technologies for managing QoS, traffic prioritization and UC&C Call Admission Control (CAC) policies are no longer adequate for delivering high level of Quality of Experience (QoE).
The introduction of Software Defined Networking (SDN) approach allows a more flexible enterprise network management improving bandwidths efficiency also for UC&C applications.
QoE challenge can be addressed in a fully converged way taking into account at the same time network status and application need.
