What is TWAMP?
TWAMP is a flexible method for measuring round-trip IP performance among any two devices in a network.
- It measures core and edge IP performance through cooperation between the routers and switches in the Network
- TWAMP connects using TCP and uses UDP packets for testing
- Supports IPv4 and IPv6
- TWAMP defines two sets of protocols
- Control Protocol
- Enables endpoints to negotiate
- Performance-measurement probes
- Defines the packet format that is needed for measuring round-trip performance.
- Uses active probe packets to measure two-way delay between two end-points in IP networks
- Timestamps are applied for high accuracy
- Typically does not requires that both end-points are time-synchronized
- One-way delay measurements require sync.
- Additional capabilities: packet loss ratio, continuity check, one-way and two-way packet delay variation
