Timing Considerations
for Mixed-media Network Design
•Cable Cable length
•Velocity Velocity of signal propagation
•Transceiver Transceiver delay
•Repeater Repeater delay
•Interframe Interframe gap shrinkage due to
repeaters
•repeater repeater is expected to regenerate all 64 bits
of preamble, despite the potential loss of some
of the strarting preamble bits because of slow
synchronization
•this his forced reintroduction of timing bits
reduces original interframe gap
•Processing Processing delay in station NIC’s CPU
