LAN Enhancement Components Component Function
*Repeater Resides in the Physical Layer of the OSI model.
Regenerates signals for retransmission. Moves packets from one
physical media to another. Will pass broadcast storms. Cannot
connect different network topologies or access methods.
*Bridge Resides in the
MAC sublayer of the Data Link Layer of the OSI model. Bridges are
used to segment networks. They forward packets based on address of
destination node. Uses RAM to build a routing table based on source
addresses. Will connect dissimilar network topologies. Will forward
all protocols. Regenerates the signal at the packet level.
*Remote Bridge Same as bridge, but used for telephone
communications. Uses STA (Spanning Tree Algorithm).
*Router Resides in the Network Layer of the OSI
model. Is used to switch and route packets across multiple networks.
Uses RAM to build a routing table based on network addresses. Shares
status and routing information to other routers to provide better
traffic management and bypass slow connections. Will not pass
broadcast traffic. Are slower than bridges due to complex functions.
Strips off Data Link Layer source and destination addresses and then
recreates them for packets. Routers can accomodate multiple active
paths between LAN segments.
*Brouter Will act as a router for specified protocols and as a
bridge for other specified protocols.
*Gateway Resides in the Transport, Session, Presentation and
Application Layers of the OSI model. Used for communications between
different network types (i.e. Windows NT and IBM SNA). Takes the
packet, strips off the old protocol and repackages it for the
receiving network.
*Multiplexer Device that can divide transimissions into two or
more channels. Multiplexing - Several signals from different sources
are collected into the component and are fed into one cable for
transmission.
*Spanning Tree Algortithm - was developed for bridges to determine
the most efficient network in path when there are multiple paths to
choose from.
