Frame Relay and ATM (Asynchronous Transfer Mode) are two different types of networking protocols used to transmit data over high-speed networks.
Frame Relay is a packet-switching technology that uses virtual circuits to transmit data between devices. It is a cost-effective solution for transmitting data over wide area networks (WANs) with a high level of reliability. In Frame Relay, data is transmitted in small packets called frames. These frames are sent through virtual circuits, which are pre-established connections between two devices. Frame Relay is commonly used for voice and data communication between geographically dispersed locations.
ATM is a high-speed networking protocol that uses fixed-length cells to transmit data over a network. ATM was originally designed for use in high-speed WANs, but it can also be used in local area networks (LANs) and metropolitan area networks (MANs). In ATM, data is transmitted in fixed-length cells, each of which contains a small amount of data along with addressing and control information. ATM is capable of handling high-bandwidth applications such as videoconferencing and multimedia content delivery.
One of the key differences between Frame Relay and ATM is the size of the packets they use to transmit data. Frame Relay uses variable-length packets, while ATM uses fixed-length cells. Another difference is that Frame Relay is considered to be a connection-oriented protocol, whereas ATM is a connection-oriented protocol that also supports connectionless communication.
In summary, Frame Relay and ATM are two different protocols used to transmit data over high-speed networks. While they have some similarities, such as the use of virtual circuits and the ability to transmit data over WANs, they differ in terms of packet size and whether they are considered to be connection-oriented or connectionless protocols.
