The system performs a distribution operation defining when a flow is processed by the first and/or the second stateful stage. The first and/or second FSM table is extended with states and transitions that support the distribution operation. The first and/or second stateful stage executes an evaluation operation that executes the distribution operation. The evaluation operation provides a criterion for moving a particular flow from one of the first or second stateful stage to the other stateful stage. The first and second stateful stages are included in a software-defined networking (“SDN”) switch. The distribution operation operates within defined capabilities of a software and/or hardware pipeline of the SDN switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Software-enhanced stateful switching architecture","description":"A stateful packet processing system includes: a first stateful stage including a first state table and a first finite state machine (“FSM”) table; and a second stateful stage including a second state ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11522813","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.
