TWAMP – Two Way Active Measurement Protocol
The upgraded version of One Way Active Measurement Protocol. http://tools.ietf.org/html/rfc4656#section-2
The One-way Active Measurement Protocol [RFC4656] (OWAMP) provides
a common protocol for measuring one-way metrics between network
devices. OWAMP can be used bi-directionally to measure one-way
metrics in both directions between two network elements. However,
it does not accommodate round-trip or two-way measurements. This
memo specifies a Two-way Active Measurement Protocol (TWAMP), based
on the OWAMP, that adds two-way or round-trip measurement
capabilities. The TWAMP measurement architecture is usually
comprised of two hosts with specific roles, and this allows for
some protocol simplifications, making it an attractive alternative
in some circumstances.
