DPI software to boost Wi-Fi network performance
A technical collaboration between Rohde & Schwarz and Keenetic will improve QoE, QoS and strengthen network security for wireless home and business applications.

A Rohde & Schwarz company, ipoque GmbH has announced that Keenetic Limited has licensed their deep packet inspection (DPI) engine R&S®PACE 2 to add granular IP traffic visibility to the entire Keenetic portfolio of wireless Wi-Fi routers. The DPI engine provides detailed insights into network traffic with application and user-level visibility. This visibility is key for Keenetic to meet customer needs by improving device performance, end-user experience and enhancing network security measures.

Given an exponential increase in both network data and bandwidth demands, Keenetic requires reliable and powerful DPI software with low memory consumption in order to analyze and prioritize network traffic in real time. By embedding R&S®PACE 2 into the operating system of their wireless routers, Keenetic can create application policies for thousands of applications by identifying bandwidth-heavy apps and analyzing usage trends over time. This enables their customers to prioritize, block or throttle applications or application groups and to define policies by device, user type or globally across the network.

R&S®PACE 2 only requires 400 bytes per network flow and classifies thousands of applications and protocols across diverse operating systems, application versions and service types. It covers different regions, areas and verticals, even if the traffic is encrypted or obfuscated. Weekly signature updates on applications and protocols during runtime keep the library up to date, ensuring the highest classification accuracy at any time.
