Dear Authors,

we updated the PR (https://github.com/igorlord/draft-mdt-ippm-explicit-flow-measurements/= pull/7​) including Giuseppe suggestions and other small changes on delay bit s= ection.


According to today's deadline at 18:= 00 UTC we will publish this new draft version.

Any new changes can be added startin= g from the first day of the 110 meeting (Monday 8th of March= ).

Best Regards,

Dear Fabio, Mauro, Massimo,

Thank you for the proposed changes.

It is ok to have this new algorithm for the Delay Bit independently from the Spin Bit.

Anyway, for the sake of completeness, I would suggest to c= ontinue to keep all the options in the draft.

1)    &n= bsp; We could keep mentioning in the Delay bit section (maybe with a subsection) t= he possibility to use the Delay Bit in combination with the Spin Bit. I thi= nk it is something that the reader may wonder.

2)    &n= bsp; Also, I would suggest to modify the summary table on Delay as below. The resilie= nce to the impairments could be put as medium for the Delay Bit only and hi= gher for the combination Spin Bit + Delay Bit.

Importance: High

 

Dear Aut= hors,

we propo= se a new version of draft-mdt-ippm-explicit-flow-measurements.<= /p>

 

We chang= ed the Delay Bit section proposing a new version of the algo= rithm i= ndependent from the spin bit.

 

In few w= ords, the client generates a delay sample (just one marked packet); if this= sample does not come back to the client after a time interval named "= T_Max", the client regenerates the lost sample.

 

Moreover= , if the delay sample is being reflected with a delay g= reater than a predetermined threshold (1ms by default) after the reception, the delay sample is not = reflected and the outgoing delay bit is kept at 0.

 

We have kep= t the same advantages of the "spin bit + delay bit" solution = by using only one bit for the delay calculation.

 

We'd like t= o present this new version at the next IPPM meeting. The deadline is Monday= 22nd of February. Sorry for the late submission.

 


Waiting for comments or suggestions,

Best Regard= s.
