The control unit is configured to encapsulate, to generate a flow measurement packet, a layer 2 (L2) measurement packet in a layer 4 (L4) header and an L3 header, where the L3 header includes a source L3 address within the VPN address space and associated with the measurement endpoint, and where the L3 header includes a destination L3 address within the VPN address space and associated with the remote measurement endpoint. The control unit is configured to output the flow measurement packet to the remote router."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Internet protocol virtual private network service performance monitoring","description":"An example router includes a control unit configured to receive virtual private network (VPN) routing and forwarding table (VRF) configuration data defining a VRF for a VPN and VPN address space for t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9596167","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.
