Two-Way Active Measurement Protocol
Note: I have worked on this full-time in Rust before, but I was a noob and didn’t build it properly.
Introduction
A more accurate network analysis tool for calculating round-trip delays between two devices. A better alternative to ping so to speak.
One requirement for it is that it is based on the client-server architecture, so it requires a TWAMP client/server to be present on both devices.
The RFC provides an example implementation (Appendex I) called TWAMP Light which removes the requirement of TWAMP-Control, and is a way for adopting TWAMP quickly.
Communication
TWAMP uses two protocols for it’s operation:
- TWAMP-Control
- TWAMP-Test
TWAMP-Control
Used for starting/stopping sessions and comms other than the actual test. Uses 862/tcp.
TWAMP-Test
Used for the actual test. Uses 862/udp.
Model
Example model is also present in the RFC.
