This chapter contains a complete sample TWAMP over EVPN configuration.

Two-way Active Measurement Protocol (TWAMP) is an open protocol for measuring network performance between any two devices. The TWAMP MPLS transport is implemented as part of supporting TWAMP on routers which acts as MPLS routers both in the roles of LERs as well as intermediate routers. Ocnos 6.0 also supports the end to end sta-tistics calculation when multiple paths are available between sender and reflector with multihop support.

The user can use the link delay metrics such as average, minimum, and maximum delay, and delay variance to de-termine the network latency. Using link delay metrics will enable troubleshooting latency issues or apply Traffic En-gineering (TE) solutions to meet Service Level Agreements (SLAs).

The TWAMP protocol is designed to do such measurements, and a basic implementation of this protocol has already been implemented in ocnos. This feature here is a TWAMP protocol in ocnos where the focus will be on accuracy and configurable advertisement of the measured data.
