We have started covering specific virtual network functions (VNFs) on an ongoing basis in our quarterly Service Provider VoIP and IMS Equipment and Subscribers Market Tracker - Regional. Many of the IMS core functions such as CSCF, HSS, and voice application servers are software elements that vendors have been moving from dedicated hardware to general purpose servers over the past several years. With mobile operators moving to VoLTE and large scale IMS networks, NFV has become front and center with work being done to make the network elements operational under hypervisors and NFV management and orchestration (MANO) software.
