I`m going to attempt to answer your question......bare with me....
first the windowing mechanism i take it you mean the LLC sublayer? ..i have
heard of analogys that in the LLC layer that the SSAP`s and DSAP`s (source
and destination acess points) are like windows or hooks into the higher
levels ...but i have never heard of the windowing mechanism.
also any retranmission/sequence errors within the TCP/IP stack is done by
1 the physical layer....CSMA/CD or
2 the transport layer...flow control
Do you mean the FCS/CRC ...as this ius a checksum that is checked at each
level of encap....
It sound to me that your describing CSMA/CD but i`m not sure????
if you mean the FCS/CRC (frame check sequence/Checksum)
then the answer is at all 7 "layers"
if you mean windowing and sequence checking that happens at the transport
layer.....
i am confused by yuor question as i have never heard of it...but please (and
list) tell me if i am totally misunderstanding the question...
sorry if it`s wrong
