The layer-2 device receives a first test data unit from the source device, and defines a quality datum associated with processing the first test data unit. The layer-2 device defines a second test data unit based on the first test data unit that includes the quality datum associated with processing the first test data unit. The layer-2 device sends the second test data unit to the layer-3 device. The layer-3 device defines a quality datum associated with processing the second test data unit at the layer-3 device and defines a third test data unit based on the second test data unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for assessing the quality of a data path including both layer-2 and layer-3 devices","description":"In some embodiments, an apparatus includes a layer-2 device operably coupled to a source device and a destination device and disposed within a data path (1) between the source device and the destinati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641420","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.
