The Two-Way Active Measurement Protocol (TWAMP) Client stands as a robust network performance measurement feature implemented on routers. It takes charge of initiating and managing network performance tests, and serves as a crucial part of the control session. Paired with a TWAMP server, it enables bi-directional measurements, allowing for comprehensive assessment, troubleshooting, and quality of service assurance within the network infrastructure. This feature is instrumental in maintaining optimal network performance and reliability.
