1. Two-Way Active Measurement Protocol RFC 5357
TWAMP

2. TWAMP Intro
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

3. TWAMP Cont. 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.

4. TWAMP Cont.

5. TWAMP Protocol
Control-Client Initiates a TCP connection with the Server
Server indicates its willingness to communicate
Client responds with the mode of communication
Server responds to accept the mode and give its start time.
This completes the control connection

6. TWAMP Protocol
Client request a test session with a unique TWAMP-Control message.
Sever responds with its acceptance and supporting informtion
More than one test session may be requested with additional messages
Client initiates all requested testing with a start sessions message
Sever acknowledges
When testing complete client sends a message to stop all test sessions.

8. Conclusion TWAMP is a non-proprietary method of testing IP networks.
Unlike ping and traceroute TWAMP works directly with switches and routers to test network performance.
No proprietary suite like TCP/IP is required to perform testing on network devices.
