The method includes inserting a respective monitoring rule(s) in each switch, mandating for each switch, forwarding a received rule matching packet to a next switch, and further mandating for the first switch and the last switch, sending a PacketIn message to a controller. The method includes inserting, in each switch, a respective monitoring probe(s) matching the respective monitoring rule(s) in a same switch to initiate mandates specified by the respective monitoring rule(s) in the same switch responsive to an arrival of the packet thereat. The method includes time-stamping the PacketIn messages to generate PacketIn timestamps, aggregating the PacketIn timestamps, and estimating the path latency from an aggregation of PacketIn timestamps."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Patent latency monitoring in software-defined networks","description":"In a software defined network having switches including first and last switches and intermediate switches, wherein a default routing path exists between the first and last switches, a system and metho","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9654372","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.
