Question

After 4th collision in ethernet, find the maximum time that the adapter waits until sensing the channel again for a 100 mbps broadcast channel?

Answer 1

Waiting time for a 100 Mbps broadcast channel is 0.512 ms

Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,

where K is drawn randomly. For K = 100,

The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms

The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms

Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms

Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms

What is a collision in Ethernet?

• A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time.
• The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them.
• On Ethernets, collisions are unavoidable.

• A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work.
• Collisions entail the application of force (there is a change in velocity).
