A hash of a flow key is computed with an initial port number. An exclusive-or (XOR) distance is computed to a desired hash, using least significant bits. An XOR is performed on a corrected pre-computed collision value, to transform the source port number to a value that hashes correctly with other elements within the flow key. The transformed source port number may then be inserted into network packets sent to a server device, such that the transformed source port number can be used in a returning RSS hash to again select the same processor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Matching port pick for RSS disaggregation hashing","description":"Embodiments are directed towards selecting a local port number for server side connections that hash to a same processor as a matching client side flow on a multiprocessor device using Receive Side Sc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9712460","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.
