Fixed-size cells simplify requirements on the switching hardware (ATM, SMDS)
-
higher speeds; shorter transit delay; more efficient handling in queues; no link level error recovery (higher protocols are responsible for error checking in payload portion)
-
switch operation based on lookups in local translation table (inPort, inVPI, inVCI) <--> (outPort, outVPI, outVCI)

Most suitable to carry voice, video,data,image over the same physical link

Referred to as cell relay

Connectionless cell switching DQDB (IEEE 802.6) used by SMDS services; connection-oriented and connection-less used in ATM (53-byte cells)
