What is DPI, or Deep Packet Analysis?

Deep packet analysis or deep packet inspection (DPI) is a type of data processing that inspects the data being sent over a computer network, and may take actions such as blocking, alerting, re-routing, or logging it accordingly. Deep packet analysis is often used to baseline application behavior, analyze network traffic, troubleshoot network performance, and assure that data is in the correct format.

NETSCOUT's Deep Packet Inspection and Analysis solutions provide in-depth analysis of captured and stored packets to investigate and decipher the root cause of exceptionally challenging network and application issues.

Keeping users happy is a critical IT mission. Holistic visibility and insight into the network, applications, servers, and user communities—and how they are performing—enables you to resolve issues before they become serious problems. When problems occur with complex multi-tiered, web and/or cloud services, you need the precision and focused offered by advanced packet analysis. Without common service-oriented metrics and in-depth packet analysis, you could be at a considerable disadvantage.
