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 × 106 bit/s) ≈ 122 μs
