RE: SARHi to all

I need an opinion of anyone familiar with WTP and SAR handling.
Here is the excerption from WTP specs. (WAP-224-WTP-20010710-a.pdf) :
" The missing packets are re-transmitted with the original Packet Sequence
Numbers. When the sender has re-transmitted the requested packets, it
reverts to wait for the original acknowledgement (for the GTR or TTR
packet). When the receiver has received all packets it acknowledges the GTR
or TTR packet according to the normal procedure,using the Ack PDU. ".

It seems to me that recevier (WAP gateway) must acknowledge resent packets
even if they don't have GTR/TTR set. Or maybe sender must set GTR on last
resent packet of a group?

Denzel,
seems that your version of SAR patch acknowledges resent packets not
imediatelly, but after 4-5 seconds. Is that an expected behaviour?

Thanks for you answers
