In some configurations, a system can partition a flow space across workers and replicate the flows within a partition to a set of workers. In some configurations, a flow cache structure can include three tiers: (1) a scalable flow processing layer for executing the actions and transformations of a flow, (2) a flow state management layer for managing distributed flow state decisions, and (3) a flow decider layer for identifying actions and transformations needs to be executed on each packet of a flow. Flow replications allow other workers to pick up flows allocated to a particular worker that is taken offline in the event of a crash or update."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed flow processing and flow cache","description":"The techniques disclosed herein improve the efficiency, reliability and scalability of flow processing systems by providing a multi-tier flow cache structure that can reduce the size of a flow table a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11258876","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.
