Hi All, I have done a preliminary working implementation of DOTS Call-Home - there is still some little used functionality to finish off. *** Issue # 1 - TCP TLS sessions https://tools.ietf.org/html/draft-ietf-dots-signal-call-home-06#section-3.1 " If UDP transport is used, the Call Home DOTS server begins by initiating a DTLS connection to the Call Home DOTS client." This works as expected where the UDP + DTLS layer roles are switched. " If TCP is used, the Call Home DOTS server begins by initiating a TCP connection to the Call Home DOTS client. Using this TCP connection, the Call Home DOTS server initiates a TLS connection to the Call Home DOTS client." With the current libcoap implementation, I am unable to create a CoAP session using TLS on an existing TCP connection - so the DOTS Client is unable to accept an incoming TCP session and then initiate TLS integrated with the CoAP session. I agree that RFC8071 only switches the TCP layer roles. However all works if the TCP + TLS layer roles are switched - in the same way that UDP + DTLS work. Enhancing the libcoap code to support only the TCP layer being switched is doable - but have no idea as to whether other CoAP implementations can handle this specific requirement. *** Not (yet) Implemented #1 - Redirected Signalling https://tools.ietf.org/html/draft-ietf-dots-signal-call-home-06#section-3.2. 2 I do not see any issues here. *** Not (yet) implemented #2 - New Conflict Cause 4 I do not see any issues here. *** Not (yet) Implemented #3 - Address sharing considerations https://tools.ietf.org/html/draft-ietf-dots-signal-call-home-06#section-3.3. 2 I do not see any issues here - just need to interface with the translators to get the appropriate information.
