The method comprises: determining that a first timing reference received by a first slave node indicates a time correction to its slave clock greater than a time correction threshold; determining whether one or more other slave nodes have received a timing reference indicating a time correction to their slave clock greater than a time correction threshold; and determining whether the first timing reference is affected by a change in path delay asymmetry based on the determining of whether one or more other slave nodes have received a timing reference indicating a time correction to their slave clock greater than a time correction threshold. Apparatus and a computer program for detecting a timing reference affected by a change in path delay asymmetry in a communications network are also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting timing references affected by a change in path delay asymmetry between nodes in a communication network","description":"A method for detecting a timing reference affected by a change in path delay asymmetry in a communications network comprising a master node having a master clock and a plurality of slave nodes each ha","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813175","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.
