Procera Deep Packet Inspection (DPI)
NAVL – The Next Generation of Deep Packet Inspection
Procera Networks’ Network Application Visibility Library (NAVL) features next-generation Deep Packet Inspection (DPI) technology, providing real-time, Layer-7 application classification and metadata extraction for network traffic. NAVL uses a combination of deep packet inspection and application classification techniques to deliver industry leading coverage and accuracy of network traffic. In addition, the sophisticated hierarchical data flow architecture produces the fastest throughput performance and lowest memory footprint in the market. NAVL is delivered as an OEM Software Development Kit (SDK) to dramatically reduce the time, cost and complexity of adding deep packet inspection (DPI) technology and true Layer-7 application intelligence to your networking infrastructure device.
Procera’s Advanced Deep Packet Inspection Technology Techniques
Deep Packet Inspection (DPI) as implemented by Procera’s Network Application Visibility Library (NAVL) includes, but is not limited to identification of network traffic packet attributes above layers 1-3 of, and extending to layers 4-7 of the OSI model (Layer 1- physical, layer 2 – data, layer 3 – network, layer 4 – transport, layer 5 – session, layer 6 – presentation, layer 7 – application). NAVL moves beyond even these, to include even more advanced application classification techniques, including Surgical Pattern Matching, Conversation Semantics, Deep Protocol Dissection, Behavioral and Statistical Analysis, Future Flow and Awareness and Flow Association.
