Switching Concepts and LAN Design
... Latency has at least three sources: – First, there is the time it takes the source NIC to place voltage pulses on the wire and the time it takes the receiving NIC to interpret these pulses. This is sometimes called NIC delay. – Second, there is the actual propagation delay as the signal takes time t ...
