Packet Transmission Time

Time to push a packet of L bits onto a link of rate R.

Formula

t = \frac{L}{R}

Variables

tTransmission time (s)

LPacket size (bits)

RLink rate (bps)

Example

L=12000 bits, R=10 Mbps: t = 1.2 ms

Did You Know?

Transmission time is separate from propagation delay — total latency adds both together.
