The network device aggregates the packet counts for a group of particular buffer queues, of the multiple buffer queues, that are not subject to a PFC restriction, to create an unrestricted aggregated count. The network device determines whether the unrestricted aggregated count exceeds a flow-control threshold for the group of particular buffer queues and sends, to an upstream queue scheduler, a flow control signal when the unrestricted aggregated count exceeds a flow-control threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmit-buffer management for priority-based flow control","description":"A network device operating in operating in a Priority Flow Control (PFC) mode receives a stream of packets for outputting on a particular port, assigns each packet in the stream of packets to one of m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520522","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.
