1.1 CLASIFICACION DE LOS MECANISMOS DE CONMUTACION
Conmutación de MENSAJES
Message switching network: A
network in which data is moved as
complete messages of arbitrary
length,
rather
than
being
subdivided into packets, which
contain a variable amount of data
but with a fixed upper limit on
length, or as cells, which contain a
fixed amount of data.
Conmutación de CELDAS
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
