What are the differences between snooping and directory protocols?

Snooping protocols use a method of monitoring traffic to determine which nodes need to receive data, while directory protocols maintain a centralized directory of nodes to manage data distribution. Would you like to know more about how each works?

Yes, can you explain how snooping protocols function?

Sure! Snooping protocols listen to the data traffic on the network and keep track of which nodes have requested which data. This allows them to send data only to the nodes that need it, reducing unnecessary traffic.

And what about directory protocols?

Directory protocols maintain a centralized list of all nodes and the data they require. When a node requests data, the protocol checks the directory to find the appropriate node to send the data to, ensuring efficient communication.

Which protocol is generally more efficient?

It depends on the network size and traffic patterns. Snooping protocols can be more efficient in smaller networks, while directory protocols may scale better in larger networks due to their centralized management.
