Re: [Roll] Fwd: I-D Action: draft-ietf-roll-rpl-observations-03.txt

Hello Rahul :

I mean that if the spec says reset trickle and I is already Imin then the timer already operates within the bounds that are expected so it does not need to be restarted. Now if I was larger than Imin at the time of the reset then it was operating out of bounds and needs to be restarted to timeout earlier. Same if K changes, e.g., by configuration. The current timer operates with the wrong parameters and should be restarted.

Makes more sense?

Hi Pascal,

Hello Rahul

I believe I undertand what you want to d but the text below is really unclear to me
“
  Implementations MUST not restart the trickle timer to the
  instantaneous value of I which could have been advanced over a period
  of time.
“
[RJ] ok. But I could not think of anything better. May be I should use asciiart and explain with an example. What do you think?

What I thought you’d write is that the trickle time needs only be restarted is one value I, K has changed, making the current run incompatible with the setting.
[RJ] This is unclear for me. Specifically "trickle time needs only be restarted is one value I, K has changed"

All the best

Hello All,

The update contains clarification regarding Trickle timer reset handling.
