[RPRWG] A simple problem on addrate

["Jiang zhou" <zjiang@xxxxxxxxxxxxxxxxxxx>]

Title: Availability of Post-Meeting Resolutions for Comments against P802.17 D2.1

 

Hi,all:

 

On page 173 the age update function.

 

At each ageinterval time, use the mac data path function to get addrate to calculate the lpaddrate.

But DON'T clear the addrate to zero for the next ageinterval to statistics addrate. So on the mac

datapath the counter maybe overflow. How to do it?

More

addRate = (addRate * (AGECOEF - 1)) / AGECOEF;
if do this calculate, can need use this age addrate update the mac datapath counter?

 

Maybe I don't understand the addRate,addRateCongested,fwRate,fwRateCongested,nrXmitRate.

I think there is five conter reside in the mac Datapath. Maybe they are 16bits or 32bits. If the mac

send bytes to the link it updates this counters.

So if the FU read these counters, does need the mac datapath to clearout the counter?

 

 

void agingIntervalUpdate ()
{
lpAddRate = ((LPCOEF-1) * lpAddRate + addRate) / LPOEF;
lpAddRateCongested = ((LPCOEF-1) * lpAddRateCongested + addRateCongested) / LPOEF;
lpFwRate = ((LPCOEF-1) * lpFwRate + fwRate) / LPOEF;
lpFwRateCongested = ((LPCOEF-1) * lpFwRateCongested + fwRateCongested) / LPOEF;
lpNrXmitRate ((LPCOEF-1) * lpNrXmitRate + nrXmitRate) / LPOEF;
normLpFwRateCongested = lpFwRateCongested / NORMCOEF;
addRate = (addRate * (AGECOEF - 1)) / AGECOEF;
addRateCongested = (addRateCongested * (AGECOEF - 1)) / AGECOEF;
fwRate = (fwRate * (AGECOEF - 1)) / AGECOEF;
fwRateCongested = (fwRateCongested * (AGECOEF - 1)) / AGECOEF;
nrXmitRate = (nrXmitRate * (AGECOEF - 1)) / AGECOEF;
}

 

Best Regards
