Jim leads Heavy Reading’s research on the impact of the NFV enabled virtualized cloud on the control plane and application layers, both in the fixed and mobile core and at the enterprise edge. This includes evolution paths of IP Multimedia Subsystem (IMS), session border controllers (SBCs), Diameter signaling controllers (DSCs), SIP based application servers, PBXs, Unified Communication (UC) and policy controllers.
In addition, Jim focuses on the security impacts that cloud and emerging cloud based technologies such as 5G introduce from both a cyber threat detection perspective, as well as the business opportunities associated with delivery of security capabilities via a managed services model.
He authors Heavy Reading's NFV & SDN Market Trackers.
