What are the four sources of packet delay in a network nodal processing?
- Queueing, link bandwidth, transmission delay, physical link length
- Queueing, processing, transmission, propagation
- Bit errors, link determination, propagation speed, transmission
- Bit errors, output link determination, packet length, propagation delay (correct)
What does the propagation delay depend on in a network?
What does the propagation delay depend on in a network?
- Output link congestion level
- Bit errors
- Link bandwidth
- Physical link length and propagation speed (correct)
Which formula describes the transmission delay in a network?
Which formula describes the transmission delay in a network?
- $d_{trans} = \frac{R}{L}$
- $d_{trans} = \frac{L}{R}$ (correct)
- $d_{trans} = L + R$
- $d_{trans} = L - R$
