2. ATM - the Basics

- sub-layer link protocol
- fine granularity multiplexing of cells
- compromise 48+5 byte fixed length cells
- switching protocol using VCs
- fast hardware-based table look-up switching
- works in conjunction with upper/lower layer protocols
- asynchronous cell transfer in synchronous containers
- data rates exceeding 600 Mbps
- limited error recovery
- QoS capable
