In telecommunication networks, the transmission time, is the amount of time from the beginning until the end of a message transmission. In the case of a digital message, it is the time from the first bit until the last bit of a message has left the transmitting node. The packet transmission time in seconds can be obtained from the packet size in bit and the bit rate in bit/s as:
- Packet transmission time = Packet size / Bit rate
Example: Assuming 100 Mbit/s Ethernet, and the maximum packet size of 1526 bytes, results in
- Maximum packet transmission time = 1526*8 bit / (100 000 000 bit/s) ≈ 122 μs

Famous quotes containing the word time:
“Lars Jorgensen: It’s this country killed my boy. Yes, by golly, I tell you Ethan—
Mrs. Jorgensen: Now Lars. It just so happens we be Texicans. A Texican is nothing but a human man way out on a limb, this year, and next, maybe for a hundred more. But I don’t think it’ll be forever. Someday this country’s going to be a fine good place to be. Maybe it needs our bones in the ground before that time can come.”
—Frank S. Nugent (1908–1965)
