TEMPORARY EDITORIAL NOTES This document is an Internet Draft, so work-in-progress by nature. It contains the following work-in-progress elements: o "TODO" statements are elements which have not yet been written by the authors for some reason (lack of time, ongoing discussions with no clear consensus, etc).https://github.com/openwsn-berkeley/ openwsn-fw/commit/961c53778fe411533d74ce24918c95400d834199 The statement does indicate that the text will be written at some point. o "TEMPORARY" appendices are there to capture current ongoing discussions, or the changelog of the document. These appendices will be removed in the final text. Munoz & Barthel Expires January 3, 2019 [Page 2] Internet-Draft 6TiSCH Example Frames July 2018 o "IANA_*" identifiers are placeholders for numbers assigned by IANA. These placeholders are to be replaced by the actual values they represent after their assignment by IANA. o "RFCXXXX" refers to the RFC number of this specification, once published. o The string "REMARK" is put before a remark (questions, suggestion, etc) from an author, editor or contributor. These are on-going discussions at the time of writing, and will not be part of the final text. o This section will be removed in the final text. 2. Tools Used All results presented in this document are collected by running the [OpenWSN] firmware in simulation mode and capturing the frame exchanged using Wireshark. These are the version of the source code used: 1. Wireshark: from version 2.9.0-80-g31aece5d (v2.9.0rc0-80-g31aece5d) and later. 2. OpenWSN firmware: https://github.com/openwsn-berkeley/openwsn-fw/ commit/961c53778fe411533d74ce24918c95400d834199 3. OpenWSN software: https://github.com/openwsn-berkeley/openwsn-sw/ commit/9c935d15b3e6b7dea5622e6173c04a0a4fd7ae5d 3.

[TEMPORARY] Known Bugs/Issues This document tracks the standardization activity, and reflects the state of the implementation. This document is updated regularly. Sometimes, the [OpenWSN] implementation falls behind on the standardization. In this section, we list the known issues or the elements that are not implemented. This section will be removed when the final version of the document is produced. o All link-layer frames are presented without link-layer security. This will be fixed in future revisions, both types of frames will then be shown: secured (what actually goes over the air) and unsecured (which Wireshark can parse). o ICMPv6 echo request packets use source and destination global addresses but their reply packets use link local addresses. 6. IANA Considerations This memo includes no requests to IANA. 7. Security Considerations This memo only presents example frames exchanged. It does not define any protocol; there are hence no security considerations in this document. 8. Acknowledgments The authors would like to thank the OpenWSN community, the 6TiSCH working group and the participants at the 6TiSCH plugtests for their feedback which has helped shape this document. 9.
