TCP end to end principle implementation on basis of IP
😕😕End to End principle 😔😔😔😔
According to the end-to-end principle, protocol features are only justified in the lower layers of a system if they are a performance optimization, hence, (TCP) retransmission for reliability is still justified, but efforts to improve TCP reliability should stop after peak performance has been reached. (WIKI defination )
Can some one illustrate scenarios where end to end argument is not effective as a solution w.r.t current internet usage

durga chThere is something called as TCP window. When TCP observes that most of the packets are being delayed /dropped , it understands there is something wrong with the network. Hence starts reducing the window size straight to half a peak load, it slowly starts incrementing the window size till the point it faces the dropping of packet.
the below daigram might help you

as you can see, the window size has been reduced to half when there is a bottleneck -
king99Thanks for the information , it helped me in understanding concept !!
