Answer
In a network based on the bus topology, deadlock is controlled through various mechanisms to ensure efficient message transmission despite the potential for contention over the shared resource, which is the bus itself. One common method is the use of protocols such as Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
Work Step by Step
Explanation:
- CSMA/CD is a protocol used in Ethernet networks, which are often implemented in bus topology configurations.
- With CSMA/CD, each node on the network listens to the bus before transmitting data. If the bus is idle, the node can transmit its message.
- If multiple nodes attempt to transmit at the same time, a collision can occur. CSMA/CD detects these collisions, and the nodes involved take steps to resolve them.
- After a collision, the nodes involved wait for a random amount of time before attempting to retransmit, reducing the likelihood of another collision.
- By detecting and managing collisions, CSMA/CD helps prevent deadlock and ensures efficient utilization of the shared bus resource in a bus topology network.
