Virtualized Evolved Packet Core (vEPC) is a major breakthrough in network function virtualization (NFV). When
asked where they have deployed NFV in production networks, communication service providers (CSPs) consistently name vEPC as one of the top answers. Why is that?
In order to maximize their processing capacity, CSPs virtualize a subset of their network applications, including
mobile edge computing (MEC), base stations (small/macro
cells) and the mobile core, because these systems use a
The mobile packet core builds the foundation of the core
network on which mobile CSPs offer IP-based services to
their customers. Implementing vEPC solutions can help
CSPs obtain the scale necessary to accommodate growing
numbers of subscribers and large amounts of traffic or
connections while controlling costs and improving on quality of experience (QoE). In the past, evolved packet core
(EPC) solutions were deployed on purpose-built hardware.
NFV enables operators to deploy EPC c
