Deep packet inspection (DPI) is a technique with many different use cases, delivering information about packet flows and content as well as allowing network operators and service providers to ensure quality of service at an application level. As more and more use cases are being implemented in the market, a common set of requirements has developed. These requirements have driven a set of architectures that deliver the level of performance, throughput and statistical data collection required to fulfill the respective task at hand. This white paper will analyze use cases, define a set of common requirements for DPI applications and outline several architectures and building blocks that simplify the creation of scalable, reliable DPI appliances.
