• Signal damping is a common phenomenon that is overcome via regeneration and retransmission of the data signals done by these devices.
• To ensure successful transfers these devices keep record of information of source address, destination address or different pathways existing through the network depending upon the switching technique being employed.
• They also detect faults and errors effectively using redundancy bits, etc. and notify the devices to further ensure fault tolerance by performing corrections while transferring data in a computer network.
• Maintenance of a definite desired flow control and response timeout during the entire course of the communication.
• Setup, grouping and direction of messages (or packets) according to their priorities is done by these devices.
• Provide network security by permitting or denying the flow of data, based on security settings.
Processes running on the intermediary network devices perform these functions:
• regenerate and retransmit data signals
• maintain information about what pathways exist through the network and internetwork
• notify other devices of errors and communication failures
• direct data along alternate pathways when there is a link failure
• classify and direct messages according to quality ofsService (QoS) priorities
• permit or deny the flow of data, based on security settings.
