Virtualization of the EPC and RAN allows a finer degree of control and programmability than ever before possible.  The network can now be segmented for different traffic, offering differentiated network resource and performance characteristics.

Network Slicing opens up an entirely new world of differentiated services, introduced at a pace never thought possible.  Enterprise offerings will become events-driven; commissioned, operated, and decommissioned in hours or days.

As the value of such high-visibility service becomes more concentrated, the CSP faces increasingly higher operational and reputational risk.  SONAR4 enables a new level of responsiveness to degradations so that ever-tighter SLAs can be met.
