Techniques for Circumventing Deep Packet Inspection (DPI)
Techniques for Circumventing DPI
Several techniques can be used to evade DPI. These strategies focus on confusing the DPI system or breaking its detection algorithms. Common methods include packet fragmentation, protocol obfuscation, injection of fake packets, and manipulation of Time-to-Live (TTL) values. Each method’s theory and practical application are discussed below.
