Thanks Maik. I don't know the technical aspects of these statements - I would like at least one other expert to please weigh in on whether these are appropriate changes. Thanks, Ethan. From: Maik Seewald (maseewal) [mailto:maseewal@cisco.com] Sent: Wednesday, April 05, 2017 7:48 AM To: Grossman, Ethan A. <eagros@dolby.com>; detnet@ietf.org Subject: Re: [Detnet] I-D Action: draft-ietf-detnet-use-cases-12.txt Ethan, all, A few comments on section: 3.1.1.2 Intra-Substation Process Bus Communications The CT/VT in the substation send the sampled value (analog voltage or current) to the MU over hard wire. -> Typically, the CT/VT send analog values. A Merging Unit (MU) converts the analog values into digital values, typically into Sampled Values (IEC 61850-9-2) The MU sends the time-synchronized 61850-9-2 sampled values to the IEDs in the substation in GOOSE message format. -> Sampled Values (SV) are defined in IEC 61850-9-2. SV are not sent as GOOSE messages (IEC 61850-8-1). They are sent as Sampled Values, completely defined in IEC 61850-9-2. Cheers.

It does contain a few minor tweaks due to feedback received from the list since publication of version 11. I know that there are still some additions that are being considered for this draft, and I expect there will be at least one more revision to incorporate them (before or as a result of WGLC). Best, Ethan. -----Original Message----- From: detnet [mailto:detnet-bounces@ietf.org] On Behalf Of internet-drafts@ietf.org<mailto:internet-drafts@ietf.org> Sent: Tuesday, April 04, 2017 12:08 AM To: i-d-announce@ietf.org<mailto:i-d-announce@ietf.org> Cc: detnet@ietf.org<mailto:detnet@ietf.org> Subject: [Detnet] I-D Action: draft-ietf-detnet-use-cases-12.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Deterministic Networking of the IETF. Title : Deterministic Networking Use Cases Authors : Ethan Grossman Craig Gunther Pascal Thubert Patrick Wetterwald Jean Raymond Jouni Korhonen Yu Kaneko Subir Das Yiyong Zha Balázs Varga János Farkas Franz-Josef Goetz Juergen Schmitt Xavier Vilajosana Toktam Mahmoodi Spiros Spirou Petra Vizarreta Filename : draft-ietf-detnet-use-cases-12.txt Pages : 81 Date : 2017-04-03 Abstract: This draft documents requirements in several diverse industries to establish multi-hop paths for characterized flows with deterministic properties. In this context deterministic implies that streams can be established which provide guaranteed bandwidth and latency which can be established from either a Layer 2 or Layer 3 (IP) interface, and which can co-exist on an IP network with best-effort traffic. Additional requirements include optional redundant paths, very high reliability paths, time synchronization, and clock distribution. Industries considered include wireless for industrial applications, professional audio, electrical utilities, building automation systems, radio/mobile access networks, automotive, and gaming. For each case, this document will identify the application, identify representative solutions used today, and what new uses an IETF DetNet solution may enable.
