In an exemplary embodiment, a primary processing core having direct WAN connectivity and a DHCP client includes a DNS proxy service module which acts as a DNS server to the platform's secondary processing cores. Each secondary processing core sends DNS queries to the primary core DNS proxy service module. A primary core DNS resolver regenerates DNS queries based on the DNS queries from the secondary cores and forwards them for resolution to WAN-side DNS servers whose IP addresses were provided to the DHCP client in response to an IP lease request. The resolved IP addresses are returned by the WAN-side DNS servers to the primary processing core, which provides them to the requesting secondary core applications or client devices, via the DNS proxy service module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DNS proxy service for multi-core platforms","description":"In a multi-core platform in which secondary processing cores do not have direct WAN connectivity, methods and apparatus are described that enable the secondary processing cores to provide DNS resoluti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9697173","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.
