The method controls multicast for different user ports on the same user-end device so as to raise security of multicast."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multicast control method in Ethernet Passive Optical Network","description":"A multicast control method in an Ethernet passive optical network, the method includes steps: (A) configuring different id for user-end devices and their user ports; labeling users on office-end devic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509115","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.
