Dear 6Lo WG, I recently submitted a draft for IPv6 over Controller Area Network and would like to call for adoption by the 6Lo WG. The title of the document is draft-wachter-6lo-can-00 [1]. Controller Area Network (CAN) is a widely used field bus initially designed for the automotive domain. It has a payload length of eight bytes for classic CAN and 64 bytes for CAN-FD. CAN only describes the data-link-layer, but various protocols already exist on top. The submitted draft introduces IPv6 over CAN (6LoCAN), a 6lo-adaption-layer to send IPv6 packets over the constrained CAN-bus. 6LoCAN uses a subset of the already widely used ISO-TP standard for fragmentation and reassembly to meet the 1280 minimum MTU requirement of IPv6. It also uses the IPHC (RFC6282) to reduce the protocol overhead of IPv6. A broad range of devices, from small and cheap MCUs to big application processors, already have CAN controllers onboard. With 6LoCAN, it is possible to create networks of resource-constrained MCUs that can leverage the broad range of protocols and security mechanisms built on top of the IP. Additionally, multiple 6LoCAN networks can be connected together or even to the internet by utilizing the routing capabilities of IP networks. A reference implementation of 6LoCAN already exists in the mainline Zephyrproject RTOS [2] tree. It includes a sample server-client application. The source for it is located under [3] and can be used on any boards supporting CAN. I am looking forward to your comments on the draft. Kind regards, Alexander [1] https://datatracker.ietf.org/doc/draft-wachter-6lo-can/ [2] https://www.zephyrproject.org/ [3] https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/net/sockets/echo_client -- Alexander Wachter, BSc Student of Information and Computer Engineering Graz University of Technology
