Q

Intermediary network devices perform some or all of these functions:

A

Regereate and retransmit communication signals
Maintain information about what pathways exist through the network and internetwork
Notify other devices of errors and communication failures
Direct data along alternative pathways when there is a link failure
Classify and direct messages according to priorities
Permit or deny the flow of data, based on security settings
