DODAG configuration as it’s name indicates is configuration. The goal is to tell dynamically how the protocol is operated as opposed to configuring all nodes separately.

RPL operates in control plane and data plane. It does proactive route setup and reactive invalidation. These are all trade offs that are chosen to optimize energy and bandwidth efficiency vs. some theoretical perfection.

The current proposal does not generate any additional transmission. Defining a new protocol to set one bit might appear more perfect but would require bandwidth and code footprint that we do not have.

You are very free to propose an alternate solution with enough details so we can understand it, even push a draft, and then the WG will make the best of all it sees.

I don't think it is the right approach, why using the DODAG configuration for compression? this compression turn on/off is not for the DODAG construction but for packets. I think we should separate configurations of the RPL routing standards and of the packet compression standards. We may add another configuration option per DODAG or another way.

What do you think?

Dear all

https://tools.ietf.org/html/draft-thubert-roll-turnon-rfc8138-03 is a simple draft that completes RFC 8138 with bits in the config option to enable turning it on in an brown field.
There’s no black magic and it would be good to progress it in the background rather than forget it.. Could we consider adoption?

All the best

Pascal
