Mixed Security Mode for the Two-Way Active Measurement Protocol (TWAMP)

Abstract

This memo describes a simple extension to TWAMP (the Two-Way Active Measurement Protocol). The extension adds the option to use different security modes in the TWAMP-Control and TWAMP-Test protocols simultaneously. The memo also describes a new IANA registry for additional features, called the TWAMP Modes registry.

Differentiated Service Code Point and Explicit Congestion Notification Monitoring in the Two-Way Active Measurement Protocol (TWAMP)

“…In the TWAMP-Modes registry defined in [RFC5618], IANA has reserved a new DSCP and ECN Monitoring Capability as follows: --------------------------+---------------------+-------- …”

IKEv2-Derived Shared Secret Key for the One-Way Active Measurement Protocol (OWAMP) and Two-Way Active Measurement Protocol (TWAMP)

“…First, the O/TWAMP Control-Client initiates the establishment of the IKEv2 SA, logs this operation, and selects the mode that supports IKEv2. Alternatively, the O/TWAMP Control-Client does not initiate the establishment of the IKEv2 SA, logs an error for operational management purposes, and proceeds with the modes defined in [RFC4656], [RFC5357], and [RFC5618]. Again, although both alternatives are feasible, they are in fact implementation specific.…”

Two-Way Active Measurement Protocol (TWAMP) Reflect Octets and Symmetrical Size Features

“…IANA has created a TWAMP-Modes registry (as requested in [RFC5618]). TWAMP-Modes are specified in TWAMP Server Greeting messages and Setup Response messages, as described in Section 3.1 of [RFC5357], consistent with Section 3.1 of [RFC4656], and extended by this memo.…”
