Role of Intermediary Devices in the network
The switch, which is basically a modern and more efficient version of the outdated hub, is a network access device. The router is an internetworking device. They are both intermediary devices. The basic functionalities of the processes that run in them are to regenerate and re-transmit data, maintain information about the pathways that exist across the network and internet, inform other devices in case of errors and transmission failures, guide data along substitute pathways when there is a failure in the link, classify and direct messages according to Quality of Service (QoS) priorities and permit or deny data flow based on security settings.
