Optimize the network environment through fixed and
mobile traffic analysis and control

Deep Packet Inspection

Deep Packet Inspection (DPI) is a technology used to inspect packets being sent over the network by examining both the headers and payload (layer 7 information). In terms of network analysis, DPI is used to identify and analyze protocols and applications used on a network in real time.
NTELS DPI is capable of interfacing with PCEF via Gx, TDF via Sd, OCS via Gy, and OFCS via Rf+. The technology helps you optimize a fixed/mobile network environment through the following functions: traffic management, traffic analytics, and usage management.
