In one embodiment, a mapping specifying association of respective keywords to corresponding unique pattern codes is maintained, with each pattern code being shorter in length compared to the corresponding keyword and being computed based on a formula. Upon receiving a network packet, a token (containing a sequence of characters) present in the network packet is first identified and the formula then applied to the identified token to generate a token code. The token is determined to match a specific keyword when the token code equals the pattern code corresponding to the specific keyword in the mapping."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Deep packet inspection (DPI) of network packets for keywords of a vocabulary","description":"An aspect of the present disclosure provides deep packet inspection (DPI) of network packets for keywords of a vocabulary.
