Hi, Sabine: Availbandwidth cost metric described in draft-ietf-alto-cost-calendar-01 is defined in ALTO performance metric draft as link specific metric, if you want to use it as aggregated metric, peformance measurement draft needs to updated to support this path bandwidth metric.
Secondly delay cost metric described in draft-ietf-alto-cost-calendar is defined in ALTO performance metric draft and has been separated into one way delay and round trip delay.Therefore two drafts need to better aligned about these attributes. -Qin____________________________________ 发件人: alto [[email protected]] 代表 Randriamasy, Sabine (Nokia - FR) [[email protected]] 发送时间: 2017年2月14日 2:45 收件人: IETF ALTO 主题: [alto] FW: I-D Action: draft-ietf-alto-cost-calendar-01.txt Hello, "draft-ietf-ALTO-cost-calendar-01", that updates the "ALTO Cost Calendar presented in Berlin has just been posted. The updates include: - clean-up, - corrections on the multi-cost example for RFC7285 compatibility, - updates in the text according to the simplified IRD format in the version of last July 2016 No modifications were done on the design posted at IETF96-Berlin. No updates were done on sections 1 and 5 and some sections like 4.3 may be removed. The WG feedback is more than welcome on this draft.
