An ATMATM stands for Asynchronous Transfer Mode. It is a mode of transporting data at high speed from one point to another. With ATM, you can transmit voice, data, and video in small data packets over a single network. It can carry traffic at speeds up to 622 Mbps. Data is transmitted in fixed-length cells, giving it advantages over other data transfer methods. ATM is a cellular switching network that takes data and divides it into 48 bytes. These bytes are then appended to a 5-byte header which will contain the source and destination information. The use of cell switching and multiplexing is used and information is carried in a calculated manner. This method ensures that your transmission is constant and has guaranteed capacity. ATM is different from other time-division multiplexing technologies, which use a time-sharing transmission method. With TDM (time division multiplexing), the user has a time slot in which they can send data. The user can only send data when their turn comes and if there is no data to send, the slot is sent empty. ATM is different from where slots are based on an on-demand system. Like the OSI model of data transmission, the packet is sent with identifying headers so that the source is known. ATM networks are made up of switches and endpoints. The switch takes packets from other switches or endpoints. Its responsibility is to update the header, front end of the transmitted data and send it to the destination or end point. The end point looks a lot like what is shown, it is the destination of the data packet. Each network packet is considered independent of the packet that precedes and follows it. For this reason, the network is called a connectionless network. The transferred information is divided into 53 eight-bit bytes called equal-length bytes. The first five bytes of the cell contain the source and destination information and the rest contain the payload. It was chosen as a compromise so that it is short enough to be acceptable for voice communication, it is short so as not to cause delay issues, forward error correction can be used, and it minimizes the number of bytes necessary to transmit in the event of a problem. error.
