The method comprises, upon or immediately prior to departure of a node from the overlay network, sending a Leave request from the departing node (or one of the neighboring nodes of the departing node aware of the departure) to each neighboring node (or each other neighboring node of the departing node), indicating the departure and containing one or more mappings for nodes not contained within the routing table of the recipient node. Each neighboring node (or each other neighboring node) receives the Leave request and uses said mapping(s) to update its routing table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining distributed hash tables in an overlay network","description":"A method of maintaining routing tables at nodes of an overlay network, where a routing table of a given node contains, for each of a set of neighboring successor and predecessor nodes, a mapping betwe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526331","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.
