suppose a computer sends a packet at the transport layer to another computer somewhere in the internet .The logical destination address of the packet is corrupted.What happens to the packet?How can the source computer be informed of the situation?
Weegy: Assuming you are using TCP/IP and not UDP, when a packet gets sent out it has both the destination address and the source address. [ Once the destination successfully receives the packet it send a response back to the source address to say it was successful. (With UDP - you just send it and dont wait for an acknowledgement that it got there OK). Therefore if the destination address or source address were incorrect, the source machine would not get a return saying all got through OK. Normally this would result in the packet being resent after a period of time. So assuming we have an incorrect address, the packet will eventually be delivered to the wrong destination (that system might send back that it recieved it OK - so that could be a problem - but hopefully it would ignore it - a bit like I do with letters I dont want to recieve - depends on firewall policies). Otherwise it will fail quite quickly when it cant be routed to a host, in which case you would get an error message back. (Using the source address). ] (More)
