A second type node is directly linked to a first type node by a fail transition. A first type node is directly linked to a second type node by a match transition. An IP address lookup system has memory for storing a tree data structure and a controller for storing and loading an incoming IP address. The system has a finite state machine having three stages including a first stage for loading the IP address and performing a length calculation, a second stage for searching the data structure to find a match, and a third stage for determine the next-hop address index."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"String lookup using three-transition tree structure","description":"A tree data structure for storing strings of searchable data divided into substrings has at least one first type node that has a substring associated with it and at least one second type node that doe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538999","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
