The One-way Active Measurement Protocol (OWAMP), specified in RFC
4656, 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.  [STANDARDS TRACK]
