Final answer:
The payload of an ATM cell is 48 bytes. ATM cells have a total size of 53 bytes, with the remaining 5 bytes dedicated to the header for routing and traffic management.
Step-by-step explanation:
The size of the payload of an ATM cell is 48 bytes. An ATM cell is comprised of a small fixed-size cell with a total size of 53 bytes, where 5 bytes are allocated for the header, which contains information required for routing and traffic management, and the remaining 48 bytes are dedicated to the payload, which carries the actual data being transmitted. In contrast to other communication protocols which may use variable sized packets, ATM employs a fixed cell structure primarily intended to facilitate rapid packet switching and support diverse types of traffic such as voice, video, and data simultaneously.
The payload of an ATM (Asynchronous Transfer Mode) cell is 48 bytes. An ATM cell is a fixed-length packet used in telecommunications networks. It consists of a 5-byte header and a 48-byte payload. The header includes information such as the virtual path identifier (VPI) and virtual circuit identifier (VCI), which are used to route the cell through the network.
