Internet protocol virtual private network service performance monitoring

摘要

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 the VPN, receive configuration data defining a measurement endpoint for measuring performance of a layer 3 (L3) service and associating the measurement endpoint with a remote measurement endpoint of a remote router. 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.

1. A method comprising:
receiving, by a router, virtual private network (VPN) routing and forwarding table (VRF) configuration data defining a VRF for a VPN and a VPN address space for the VPN; receiving, by the router, configuration data defining a measurement endpoint for measuring performance of a layer 3 (L3) service and associating the measurement endpoint with a remote measurement endpoint of a remote router; encapsulating, by the router, to generate a flow measurement packet, a layer 2 (L2) measurement packet in a layer 4 (L4) header and an L3 header, wherein the L3 header comprises a source L3 address within the VPN address space and associated with the measurement endpoint, and wherein the L3 header comprises a destination L3 address within the VPN address space and associated with the remote measurement endpoint; and outputting, by the router, the flow measurement packet to the remote router.
