DPI Testing

Deep Packet Inspection (DPI) functionality allows network devices such as content-aware switches and routers, next generation firewalls, intrusion prevention systems (IPS), and application delivery controllers to inspect and take action based on the contents and context of packets as they travel across the network.

DPI receives a lot of attention, primarily due to the controversy over privacy concerns and P2P bandwidth shaping. Often, these debates overshadow the important role of DPI in providing value for increased security, tiered services and data loss prevention. Testing DPI functionality is critical for network equipment manufacturers producing these devices and service providers offering these services.

Deep Packet Inspection (DPI) Testing Overview

DPI functionality allows network devices such as content-aware switches and routers, next generation firewalls, intrusion prevention systems (IPS), and application delivery controllers to inspect and take action based on the contents and context of packets as they travel across the network. DPI is heavily leveraged in helping to prevent buffer overflow attacks, denial of service (DoS) attacks and intrusions.

Deep Packet Inspection (DPI) Testing Requirements

Effective testing of DPI functionality requires an authentic blend of application traffic, combined with live security strikes, at speeds of 10 gigabits per second.

Deep Packet Inspection (DPI) Testing Example

In an effort to help in the testing of DPI capabilities, BreakingPoint has introduced a test methodology and video series that can be used as a guide. BreakingPoint CTO Dennis Cox and Systems Engineer Nimrod Kravicas created the test methodology for Deep Packet Inspection (DPI) based on live testing of DPI capabilities of network equipment. Below you will find an informative video, broken into three chapters, describing DPI testing. Please click on the book icon for the different chapters and you can also download the DPI testing methodology documentation.
