"If the average packet is broken up into say 10 frames and 20% of those frames are lost, it may take a very long time for the packets to get through. If individual frames are acknowledged and retransmitted, entire packets get through much faster"
I am trying to decode what is this text trying to say-:
1) We have 10 frames.
2) 20% of those frames are lost. i.e 2 frames are lost.
3) Entire packet takes long time to get through. WHY? (Is it because it has to retransmit the whole packet again)
In another case, 1) We acknowledge each frame and retransmit it.
2) Entire packets get through much faster. HOW?? (Is it because single frame goes faster than whole packet)?
