Advanced DPI engines for protocol and application classification

Our DPI engines are based on deep packet inspection technology and advanced methods such as machine learning and deep learning to identify and classify network traffic by applications and protocols, delivering traffic information in real-time to support use cases such as traffic management and safeguarding networks from cyber threats.

Discover our advanced scalar packet processing (SPP)-based DPI engine R&S®PACE 2 and our vector packet processing-based (VPP) DPI engine R&S®vPACE designed for virtual and cloud-native network functions. R&S®vPACE and R&S®PACE 2 form a DPI suite that enables virtualized and cloud-native architectures to be powered by deep network intelligence regardless of their underlying packet processing technology.
