Randriamasy ÊÊÊÊÊÊÊhttps://tools.ietf.org/html/draft-ietf-alto-cost-calendar-02ÊÊ - Reviewed all updates - Discussion Items - - RY several time granularities. Client can aggregate itself ? => SR: yes the server should provide finest granularity. (TODO: the client SHOULD interpret the time interval size as the finest available from server). - Richard / Sabine agree to move ahead on granularity response - Sabine - The ALTO server provides the finest grain value for the time-intervalÊ - Jan: After issues herein are closed does the team agree this should WGLC (hum) - Result: No hums against moving it to WGLC once issues/open items are resolved - Please make the resolutions on this on the list 1355 - 1410 15' ALTO cost context, S. Randriamasy ÊÊÊÊÊÊÊhttps://tools.ietf.org/html/draft-randriamasy-alto-cost-context-02 - Reviewed Concepts and Updates per WG feedback - Questions:Ê - Dawn - One suggestion is to make suggestion to specifiy the order of the response (has this been considered)? - Different options were discussed. Will continute to mailing list. - Would adding context to the cost add extra privacy concerns? - This should be discussed in the document. - Richard - point out that this is part of a more generalized issue of a type system in ALTO - Type system was urged to be a future dicussion on this matter - Richard: we need reconsider cost type design (type, mode, where fit context?) - Seb: IANA considerations ? ==> SR yes we need look at other IETF Work and consider IANA registration. - For now, chair ask is to move ahead but since it is not part of the milestones we will leadÊ 1410 - 1425 15' ALTO incremental updates, R. Yang ÊÊÊÊÊÊÊhttps://datatracker.ietf.org/doc/draft-ietf-alto-incr-update-sse/ - Overview of changes - Does WG believe this is ready for WGLC after items are completed (hum)? - No reaction either way - Sabine - Main task is complete but needs work to specify who is sending a SSE and for what reason - Suggestion is that we can make the Client/Server roles more explicit - JS: JSON patch important for CDNI. WG seems now more active on that one. - SR: needs clarification on who requires what for what - RY: yes we will need to clarify that 1425 - 1435 10' CDN Footprints and Capability Advertisements, R. Yang ÊÊÊÊÊÊÊhttps://www.ietf.org/id/draft-seedorf-cdni-request-routing-alto-10.txt ÊÊÊÊÊÊ (This is a WG draft; needs to be resubmitted with the correct name.) - Jan presenting - Advanced design is being looked at but the focus is the basic design - Richard - Discussion wrt the envelope name - outcome is to use somehting like "cdni/fci" 1435 - 1450 15' ALTO path vector, D. Chan ÊÊÊÊÊÊÊhttps://datatracker.ietf.org/doc/draft-ietf-alto-path-vector/ - Discussed 3 remaining design issues - Point raised about why this technique for MIME is not used in SSE - Privacy implications exist for cross product query but PID flows don't 1450 - 1455 05' Extensible property maps for ALTO, D. Chan ÊÊÊÊÊÊÊhttps://datatracker.ietf.org/doc/draft-roome-alto-unified-props-new/ ÊÊÊÊÊÊ (This is a WG draft; needs to be resubmitted with the correct name.) -Ê With no time left, discussion will be deferred to the list -Ê Jan: Please don't add use cases every 2 months or it will never get done 1455 - 1500 05' ALTO cross-domain server discovery, S. Kiesel ÊÊÊÊÊÊÊhttps://datatracker.ietf.org/doc/draft-ietf-alto-xdom-disc/ -Ê Richard - Document is useful but if we can carve out the principal it would be helpful, can you come up with more clear principles? - JS: seb said will look at it. -Ê Will review Richard's comments and move to WGLC 1500 - 1509 09' ALTO cellular address extension, S. Randriamasy ÊÊÊÊÊÊÊhttps://tools.ietf.org/html/draft-randriamasy-alto-cellular-adresses-00ÊÊ -Ê Proposed based on prior work -Ê Lyle - Ignore leading 0 concern as they are about LR(0) parsing and over the wire frame alignment 1509 - 1518 09' ALTO extension: Flow-based cost query, J.
