ABI Research：2024年开源DPI的现状： 挑战、机遇与替代方案报告（英文版）

Deep packet inspection (DPI) is a traffic detection technology that is used prevalently across today’s IP networks to manage and secure traffic flows. DPI involves the identification of packet payloads, which enables networks to ascertain the underlying applications and service types. While shallow packet inspection confines traffic analysis to packet header data, such as port numbers and source URL, DPI deploys advanced analytical techniques and comprehensive signature libraries to d
