The IESG has approved the following document: - 'Two-Way Active Measurement Protocol (TWAMP) Data Model' (draft-ietf-ippm-twamp-yang-13.txt) as Proposed Standard This document is the product of the IP Performance Measurement Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-ippm-twamp-yang/ Technical Summary This document specifies a data model for client and server implementations of the Two-Way Active Measurement Protocol (TWAMP). The TWAMP data model is described through Unified Modeling Language (UML) class diagrams and formally specified using YANG. The Two-Way Active Measurement Protocol (TWAMP) [RFC5357] is used to measure network performance parameters such as latency, bandwidth, and packet loss by sending probe packets and measuring their experience in the network. To date, TWAMP implementations do not come with a standard management framework and, as such, configuration depends on proprietary mechanisms developed by the corresponding TWAMP vendor. This document addresses this gap by formally specifying the TWAMP data model using YANG. Working Group Summary This document was presented and discussed in IETF96, IETF97, IETF98 and IETF99. There has also been discussion on the email list. There were questions raised as to the inclusion of TWAMP Light in this document. The consensus was that TWAMP Light is not adequately specified as a protocol to base a YANG model on. Document Quality The document was reviewed and comments were provided in both the IETF meetings and on the IPPM WG mailing list. A YANG doctors review was requested for the YANG module in the document and was provided by Jan Lindblad. A number of Jan's suggestions were implemented. AT&T has an implementation. Viavi was working on an implementation for testing Ethernet. Personnel The Document Shepherd is Nalini Elkins. The Responsible Area Director is Spencer Dawkins.
