Seems very trivial but I'm confused which one of these correctly define transmission time.
Time taken by a message to reach receiver.
Time taken to push message on the link by the sender.
Which one is correct one?

- Time taken by a message to reach receiver : Propagation delay or time
- Time taken to push message on the link by the sender : Transmission time
Transmission time is the time from the first bit until the last bit of a message has left the transmitting node. Or, in simple word it's the amount of time required for the router to push out the packet.
Packet transmission time = Packet size / Bit rate

$\begingroup$ @Mr.Sigma. yep, in other words you can say it's taken by one bit to travel from one node to the other (it's proportional to the length of the wire, mainly). $\endgroup$– finnDec 4, 2018 at 13:06
