TWAMP

• Two-Way Active Measurement Protocol
• RFC 5357

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.

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.

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.
