When the particular address is not within the binding table, the device causes the router to not store the particular address in a neighbor discovery (ND) cache at the router (e.g., by responding to clear the cache, or ignoring to prevent state from being created). In another embodiment, the ND-requesting router ensures that the particular address is not kept in an ND cache at the router in response to the device indicating that the particular address is not within its binding table (e.g., an explicit response to clear, or absence of instruction to store state)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protecting address resolution protocol neighbor discovery cache against denial of service attacks","description":"In one embodiment, a device (e.g., switch or registry) maintains a binding table for all internet protocol (IP) addresses in a particular subnet associated with the device, and in response to receivin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9654502","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.
