Abstract
According to the present specification, a method for inspecting a high-speed network packet payload by a terminal includes: a step of receiving L7 (Layer 7) policy related to containers from a user; a step of extracting string patterns to be inspected for each of the containers on the basis of the L7 policy through a pattern compiler; a step of creating a deterministic finite automaton (DFA) on the basis of the extracted string patterns through the pattern complier; and a step of converting a state transition table of the deterministic finite automaton into a match-action table through the pattern compiler and storing the match-action table in an eBPF (extended Berkeley Packet Filter) map for a payload inspection engine.
