Computer Network Switches
By Stephen Bucaro
A bridge or router may be referred to as a "switch" because it uses information in the
data packet to choose a path from one network segment to another. A bridge may be referred to
as a "layer 2 switch" because it uses information from layer 2, the Data Link layer of
the OSI model. A router may be referred to as a "layer 3 switch" because it uses information
from layer 3, the Network layer of the OSI model. A network device that uses a higher layer of
the OSI model may be referred to as a "layer 4 switch", and so on.
