What is the difference between transmission time and propagation time?

What is the difference between transmission time and propagation time?

b. What is the difference between transmission delay and propagation delay? Transmission delay is the time needed to put the entire packet on the link and is dependent on the length of the packet, while the propagation delay is needed time for one bit to reach to the other end of the link.

What is the relationship between propagation speed and propagation time?

Propagation delay The ratio of actual propagation speed to the speed of light is also called the velocity factor of the medium. The propagation delay of a physical link can be calculated by dividing the distance (the length of the medium) in meter by its propagation speed in m/s.

Why the propagation delay is two times the frame transmission time in CSMA?

In CSMA/CD, the size of a frame must be large enough so that collision can be detected by sender while sending the frame. So, the frame transmission delay must be at least two times the maximum propagation delay.

What has the highest propagation speed?

Examples of propagation velocities in different tissues are given below 2 :

• air: 330 m/sec.
• fat: 1450 m/sec.
• water: 1480 m/sec.
• liver: 1550 m/sec.
• kidney: 1560 m/sec.
• blood: 1570 m/sec.
• muscle: 1580 m/sec.
• bone: 4080 m/sec.

What is speed of propagation formula?

The relationship between the propagation speed, frequency, and wavelength is vw=fλ. The relationship between the propagation speed, frequency, and wavelength is vw=λf. The relationship between the propagation speed, frequency, and wavelength is vw=√fλ.

What does propagation delay depend on?

Factors that affect propagation delay are: the way it is measured, the amount of overdrive, the supply voltage, the output driver supply voltage, capacitive loading, the common mode voltage, the configuration (inverting or non-inverting), the edge on which one measures (rising or falling) and temperature.

What is the difference between propagation delay and transmission delay?

Propagation delay is the time taken by a bit (Mostly MSB ,Here 1) to reach from sender (A) to receiver (B). Transmission Delay : Amount of time required to pump all bits/packets into the electric wire/optic fibre.

What is the total time required to send a frame?

Hence, the total time required to send a frame is: Total time= Td (Transmission Delay) + Tp (Propagation Delay for data frame) + Tp (Propagation Delay for acknowledgment frame) The sender is doing work only for Td time (useful time)and for the rest 2Tp time the sender is waiting for the acknowledgment.

How is the propagation delay of a wave calculated?

Propagation Delay: Time taken by the last bit of the frame to reach from one side to the other side is called propagation delay. It is calculated by dividing the distance between the sender and receiver by the wave propagation speed.

Which is the same as tranmission time of a frame?

Frame Time: Same as Tranmission time of a frame. Round-trip delay: Round-trip delay is associated with a data link. It is the time delay between the first bit of a block being transmitted by the sender and the last bit of its associated acknowledgement being received.
