[6tisch] Clarification on MSF-06

[Christian Hopfner <[e-mail]>]

Hi authors,

I may raise a clarification question before issuing WGLC for this draft.

In the past there was a section in the draft dealing with neighbor polling which seems to me beeing an important topic in terms of schedule consistency.

In the latest version I don't see a mechanism which explains how a parent keeps its schedule clean after some children silently disappeared (e.g. batteries are gone). As per my understanding in such a case the negotiated RX cell towards the child remains in the schedule forever right?

Previously this was handled by neighbor polling. Which required the parent to send KA packets in a periodic manner to its childset. (This could be identified by evaluation of the neighbor set where a negotiated RX cell was scheduled to)

What is the idea now how to deal with that issue?


Mit freundlichen Grüßen I Best regards
