ROUTER is a complex program running on a computer, a physical device, which forwards data packets over a WAN or LAN to another. Based on routing protocols, a router reads destination network addresses of each packet, which arrives to its server and then decides on sending them via the best route possible which is based on cost, traffic load, speed, and other factors. Routers usually work at third level of protocol stack, while switches and bridges work at second level of protocol stack.
VOICE OVER ATM enables a router to carry calls and faxes and other voice traffic over an Asynchronous Transfer Mode network. Voice traffic over Asynchronous Transfer Mode network is encapsulated via a special method for multiplexed voice.
WIDE AREA NETWORK or WAN communications network is used to connect computers and other communication devices using public or private connections.
