Similar to OWAMP, TWAMP consists of two inter-related Relationship of Test and Control Protocols "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in thisĭocument are to be interpreted as described in RFC 2119. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", Some protocol simplifications, making it an attractive alternative to The TWAMP measurement architecture is usuallyĬomprised of only two hosts with specific roles, and this allows for (reflector) to enable greater accuracy (processing delays can beĪccounted for). TWAMP employs time stamps applied at the echo destination Or round-trip metrics (henceforth in this document the term two-wayĪlso signifies round-trip), in addition to the one-way metrics of OWAMP to define an open protocol for measurement of two-way TWAMP uses the methodology and architecture of This memo specifies the Two-Way Active Measurement The ping tool), and issues with this method are documented in Section 2.6 of. However, the most common facilityįor round-trip measurements is the ICMP Echo Request/Reply (used by Round-trip delay, and measurement support at the remote end may be Synchronization between local and remote clocks is unnecessary for Two-way measurements are common in IP networks, primarily because However, OWAMP does not accommodate round-trip or two-way Measurements, the One-way Active Measurement Protocol (OWAMP) The IETF hasĪlso completed a protocol for the control and collection of one-way Standard for the round-trip delay metric. The Internet Engineering Task Force (IETF) has completed a Proposed 22 Appendix I - TWAMP Light (Informative). Relationship of Test and Control Protocols. RFC 5357 Two-Way Active Measurement Protocol October 2008ġ. Usually comprised of two hosts with specific roles, and this allowsįor some protocol simplifications, making it an attractive Protocol (TWAMP), based on the OWAMP, that adds two-way or round-trip This memo specifies a Two-Way Active Measurement However, it does not accommodate round-trip or two-way Measure one-way metrics in both directions between two networkĮlements. The One-way Active Measurement Protocol (OWAMP), specified in RFC 4656, provides a common protocol for measuring one-way metricsīetween network devices. Official Protocol Standards" (STD 1) for the standardization stateĪnd status of this protocol.
