TWAMP Overview

TWAMP (Two-Way Active Measurement Protocol) is a network performance measurement protocol that provides two-way or round-trip measurements rather than simply unidirectional capabilities. It is used to measure network performance between two units in a network in order to check Service Level Agreement (SLA) assurance and provide SLA related metrics.

TWAMP is supported as a Session-Sender and as a Session-Reflector. TWAMP metric types are collected by the Telemetry.

Assurance Sensor F100 and F25 TWAMP:

• Is manageable via CLI (Command-Line Interface), SNMP (Simple Network Management Protocol), and NETCONF (Network Configuration Protocol) and is compatible with both IPv4 and IPv6 protocols
• Supports up to 1,000 OE-SVI (Offload Engine Switch Virtual Interface) sessions. An OE-SVI is an abstract object and is used to associate a network interface to an underlying Ethernet Service. It typically contains the following parameters:
• Ethernet interfaces or Port-Channels
• IP address (IPv4 and/or IPv6)
• Netmask and/or Prefix Length
• Default Gateway and/or Next-Hop address
• Route
• A reference to the underlying Layer 2 domain
• Manages up to 256 static routes
• Can handle up to 6,000 TWAMP sender sessions
• Manages up to 6,000 TWAMP reflector sessions
• Supports periodic intervals of 10 ms, 20 ms, 33 ms, 50 ms, 100 ms, and 1000 ms
• Can achieve an aggregate rate of 60,000 packets per second (PPS) when configured with a padding length above the minimum size

Additionally:

• TWAMP Sender can reach an aggregate rate of 600,000 packets per second (PPS) when all sessions use a padding length equal to the minimum size
• TWAMP Telemetry measures intervals of 60 seconds, 300 seconds, 600 seconds, 900 seconds, or 3600 seconds
• OE-SVI can be simultaneously configured with both IPv4 and IPv6 addresses
