The evolved packet core (EPC) is the all-IP core network for LTE. It orchestrates major functions of the wireless network such as user authentication, mobility, policy enforcement, charging, deep packet inspection (DPI), interworking with legacy 2G/3G/CDMA networks and many others. It enables end-to-end IP connectivity for the delivery of services.
Delivering true wireless broadband with high quality of experience (QoE) to subscribers places tremendous demands on the EPC, compounded by ever-growing data hungry applications such as video streaming and sensitive real-time applications such as VoLTE. Consequently, the EPC is experiencing unseen levels of both user- and control-plane traffic.
