When the consumer sends the packet, the highest layer tells it to go to Router A, the primary cease on the circuit. When it’s there, Router A takes off the primary layer. The following layer instructs Router A to ship the packet to Router B.
Router A doesn’t know the last word vacation spot, solely that the packet got here from the consumer and went to B. Router B peels off the subsequent layer, passing it down the road to Router C, and this course of continues till the message reaches its vacation spot.
At every cease, the node solely is aware of the final place the packet was and the subsequent place it is going to be. No node information the whole path of information, and neither would anybody observing the message exit, assuming your first three servers are configured appropriately.
