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

ICMP Echo (“Ping”): Internet Control Message Protocol (IETF RFC 792). Used for
connectivity check and rough roundtrip delay estimations between any IP devices
IP SLA: Proprietary Cisco method for measuring performance across router
networks
TWAMP is mostly suitable for premium
L3 business services (with SLA
guarantees) and for LTE backhaul
service assurance!

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
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.

TWAMP Light Reflector
Built in NTP Syncronization
Layer 3 Packet Loss, Jitter and Delay Measurement
Very compact size
Available in wide range of IP Networks
Overall cost reduction
FIT (is an affiliate of TAC) developed the LOOKOUTeyes™ TWAMP Module, a new class of softwarethat integrates intelligent and innovative system functions into an LOOKOUTeyes™. IP Network Performance Measurement tools are essential for service turn-up and Service Level Assurance in IP networks. The LOOKOUTeyes™ provides operators with these tools for monitoring and troubleshooting IP services by simply replacing a conventional Network Performance Management tools with a LOOKOUTeyes™. This solution reduces system and network complexity, and offers efficiency and effectiveness while generating CAPEX & OPEX savings and providing continousimprovement.
The LOOKOUTeyes™ modules provide customers an easy solution for monitoring and troubleshooting using standardized protocols at various operational layers:
- LOOKOUTeyes™ TWAMP Module : IP layer service monitoring using TWAMP Light according to RFC5357
- LOOKOUTeyes™ IPSLA Module : IP layer service monitoring (availability, packetloss, jitter, delay) using its own propriety method designed to support ITU-T Y.1540-41 and based on RealtimeJitter calculation as described in RFC 1889
