Segmentation and Reassembly refers to the process used to fragment and reassemble packets so as to allow them to be transported across Asynchronous Transfer Mode networks. Since ATM's payload is only 48 bytes, nearly every packet from any other protocol has to be processed in this way. Thus, it is an essential process for any ATM node.
