Updates to LMAP Framework: Enhancing Measurement Methods and Task Suppression

DESCRIPTION

This document details the progression of the LMAP (Large-Scale Measurement of Broadband Performance) framework from version -03 to -07. Key updates include changes to measurement methods, new roles for task management, and the introduction of a suppression flag for tasks. It also clarifies the usage of measurement agents and peers across deployment scenarios, ensuring consistent terminology and practical examples. The discussions from recent WGLCs led to consensus on the current state and readiness for IESG review. This version aims for clarity and conciseness in its presentation of complex topics.

  2. Progress since last IETF • -03 to -04 • Updates from 1st WGLC and agreements in London IETF • Implementation & deployment decide on the granularity at which an Instruction Message works • Appendix added with examples of Measurement Agents and Peers in various deployment scenarios. To help clarify what these terms mean • -04 to -05 • Updates from 2nd WGLC • Measurement Method, specified as a URI to a registry entry (rather than a URN) • Removed mention of Data Transfer Tasks. This abstraction is left to the information model i-d • -05 to -06 • Different roles in a Measurement Method (requester and responder, for instance) • Suppression: there is now the concept of a flag (boolean) which indicates whether a Task is by default gets suppressed or not. • The optional suppression message (with list of specific tasks/schedules to suppress) over-rides this flag. • -06 to -07 • Editorials • Overall – keeping aligned with Information Model i-d • Comments in 3rd WGLC (next slide) • Thanks to Ken Ko, Dan Romascanu, Juergen Schoenwaelder • Consensus that ready for IESG • Will update in next week or two

  3. WGLC #3 comments • What does the MA do if it gets a 2nd suppress message? • Replaces the previous info • Suppress with option listing both specific Tasks and Schedules to suppress. Is this allowed? What does MA do? • Yes. MA suppresses everything in either list (the Union) • Suppression flag. • Is this an Input Parameter for the Measurement Method, or is it better to define as a new field? • Measurement Method role: • Is this an Input Parameter for the Measurement Method, or is it better to define as a new field? • Network address used for the measurements needs to be reported • Agree. Also needs adding to Info model • The time of the acquisition of the Management Results is included in the reports – is there any requirement on a minimal granularity, or clocks synchronization? • No, this is just the MA's estimate of the time • I would have preferred the document to be more concise and less repetitive. … I suggest to move section 6 into the appendix next to the deployment examples (or even better merge the section with appendix A since there is yet more redundancy) • Move S6 to Appendix

  4. That’s it … until we get IESG comments
