DPI Testing Methodology
A methodology to realistically validate the performance, security and stability of DPI capable network devices
Deep packet inspection (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. Validating DPI functionality is critical for equipment manufacturers who produce these devices and for the service providers, enterprises and government agencies that depend on these elements.
DPI Testing Methodology
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.
