Cell relay

In computer networking, cell relay refers to a method of statistically multiplexing small fixed-length packets, called 'cells', to transport data between computers or kinds of network equipment. It is an unreliable, connection-oriented packet switched data communications protocol. In computer networking, cell relay refers to a method of statistically multiplexing small fixed-length packets, called 'cells', to transport data between computers or kinds of network equipment. It is an unreliable, connection-oriented packet switched data communications protocol. Cell relay transmission rates usually are between 56 kbit/s and several gigabits per second. ATM, a particularly popular form of cell relay, is most commonly used for home DSL connections, which often runs between 128 kbit/s and 1.544 Mbit/s (DS1), and for high-speed backbone connections (OC-3 and faster). Cell relay protocols have neither flow control nor error correction capability, are information-content independent, and correspond only to layers one and two of the OSI Reference Model.
