The upper layer packet includes a virtual private network identification identifying a destination. The method also includes authenticating the upper layer packet at the egress edge device using the virtual private network identification. Upon authentication, the upper layer packet is decapsulated into a lower layer packet for the destination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Broadband access for virtual private networks","description":"A method for communicating between a source and a destination in a service provider internet protocol network includes receiving, at an egress edge device from an ingress edge device on the service pr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520681","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.
