Asynchronous Transfer Mode

Thanks for the clarification — you're asking about Asynchronous Transfer Mode (ATM) in networking. What is Asynchronous Transfer Mode (ATM)? ATM is a high-speed networking protocol designed for the transmission of data, voice, and video across networks using a fixed-size cell structure. Key Features: Fixed Cell Size : Each ATM cell is exactly 53 bytes (5-byte header + 48-byte payload). This uniformity makes it efficient for switching and multiplexing. Connection-Oriented : ATM requires a virtual circuit to be established before data transfer, ensuring reliable delivery. Supports Multiple Types of Traffic : Handles voice, video, and data traffic efficiently. Quality of Service (QoS) : Offers different levels of QoS, making it suitable for time-sensitive applications like VoIP and video conferencing. ATM Layers: Physical Layer : Defines how bits are transmitted over the physical medium. ATM Layer : Handles cell creation, routing, and switching. ATM Adaptation Layer (AAL) : Adapts higher-layer protoco…
