Chapter 6, Problem P18P

Explanation of Solution

Given:

• Given that the nodes “A” and “B” were on the 10 Mbps channel.
• Propagation delay between both the nodes is 325 bit times.

Given scenario:

Consider the node “A” starts to transmit a frame and before it finishes sending the frame, the node “B” starts to transmit a frame. If the node “A” finishes transmitting the frame before it detects that the node “B” had transmitted, then it is considered that the node “A” incorrectly believes that its frame was transmitted successfully without a collision.

Solution:

• The node “A” starts to transmit a frame at “t = 0”.
• The node “A” finish transmitting a frame at “t = 512 + 64” bit times...
