Internet Area 6TiSCH Draft This draft contains example packets exchanged by nodes implementing the following 6tisch drafts: draft-ietf-6tisch-minimal, draft-wang-6tisch-6top-sublayer, draft-ietf-6lo-routing-dispatch and draft-ietf-6lo-paging-dispatch. All packets are presented both in raw binary and fully parsed contents. This document can be used as a reference when implementing the previous mentioned drafts.

All results presented in this document are collected by running the OpenWSN firmware in simulation mode and capturing the packets exchanged using a version of Wireshark with an updated IEEE802.15.4e TSCH/6TiSCH and 6LoWPAN dissectors. These are the version of the source code used: Wireshark dissector: https://github.com/openwsn-berkeley/dissectors/releases/tag/6tisch_0.4 OpenWSN firmware: https://github.com/openwsn-berkeley/openwsn-fw/commit/98576fcdb23094a90c07c9ee615734fec14a6ee2 OpenWSN software: https://github.com/openwsn-berkeley/openwsn-sw/commit/0a60c7067af6685f2c8c986b0f9555e837725b01
