Cell switching operates in a similar way to packet switching but uses small fixed length cells for data transport. This technology is found within cell based integrated networks such as Asynchronous Transfer Mode (ATM) networks. Cell switching can handle multiple data types, i.e. voice, video and data
Cell switching is typically a high bandwidth and high speed (up to 155 Mbps) technology.
Cell switching is essentially an attempt to combine the best of circuit switching (guaranteed delivery) and packet switching (efficiency).
