  10. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN IMPORTANT There are two approaches to provide 6LoWPAN under Linux 1) External Routing Device 2) The full Linux way Slide 10 - http://www.pengutronix.de – 02/10/2016

  11. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN Just a “small” routing device What we don't do! Linux External Device … IPv6 6LoWPAN UDP TCP ... LoWPAN IPv6 IPv6 (SLIP) Slide 11 - http://www.pengutronix.de – 02/10/2016

  12. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN What we do! Linux Still AF_INET6 … UDP TCP ... IPv6 Transceiver 6LoWPAN LoWPAN Raw LoWPAN (Bus) Slide 12 - http://www.pengutronix.de – 02/10/2016

  13. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN Current Kernel Situation ● Supported 6LoWPAN Link-Layers ● IEEE 802.15.4 ● Bluetooth Low-Energy Directories ● Generic 6LoWPAN ● net/6lowpan/ ● Link-Layer 6LoWPAN specifjc ● net/ieee802154/6lowpan/ ● net/bluetooth/6lowpan.c Slide 13 - http://www.pengutronix.de – 02/10/2016

  14. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – Generic 6LoWPAN Provide a 6LoWPAN Framework ● Virtual Userspace ● ARPHRD_6LOWPAN ● Raw IPv6 view 6LoWPAN-Interface ● 1280 bytes MTU ● Framework ... ● Header handling IPv6 ● Interface registration ● Userspace API Generic 6LoWPAN Shared-Layer ● Subscribe packet-layer ● Transmit queueing Link-Layer 6LoWPAN ● Special frame handling, etc. LoWPAN Your $WHATEVER Link-Layer Can be not specified by IETF for 6LoWPAN yet Slide 14 - http://www.pengutronix.de – 02/10/2016

(T oDo) ● Load necessary modules only ● Small link-layer specifjc handling ● Abstract one userspace API ● One interface type from userspace Slide 16 - http://www.pengutronix.de – 02/10/2016

  17. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN Remember this? IPv6 6LoWPAN Needs special LoWPAN 6LoWPAN handling? Is 6LoWPAN an adaptation layer only? Slide 17 - http://www.pengutronix.de – 02/10/2016

  18. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016.

  20. Proceedings of NetDev 1.1: The Technical Conference on Linux Networking (February 10th-12th 2016. Seville, Spain) Linux – 6LoWPAN and Ndisc Don't Worry! We are for a friendly co-existence inside IPv6! 1) T alking with the Maintainers! 2) We need a plan! 3) Kernelspace vs userspace? 4) Roles and kernelspace? Slide 20 - http://www.pengutronix.de – 02/10/2016
