mechanisms. One of the most common flow control protocols for asynchronous communication is called
xon-xoff. In this case, the receiving device sends a an "xoff" message to the sending device when its buffer
is full. The sending device then stops sending data. When the receiving device is ready to receive more data,
it sends an "xon" signal.
Forwarding
When a frame is received on an input port on a switch, the address is checked against the lookup table. If the
lookup table has recorded the destination address, the frame is automatically forwarded on an output port.
Full-duplex
A system that allows packets to be transmitted and received at the same time and, in effect, doubles the
potential throughput of a link.

GARP Information Propagation
GIP is the propagation of information between GARP participants for the same application in a bridge is
carried out by a GIP component.
GARP Multicast Registration Protocol
GMRP provides a mechanism that allows Bridges and end stations to dynamically register (and
subsequently, de-register) Group membership information with the MAC Bridges attached to the same LAN
segment, and for that information to be disseminated across all Bridges in the Bridged LAN that support
Extended Filtering Services. The operation of GMRP relies upon the services provided by the GARP.
GARP VLAN Registration Protocol
GVRP allows workstations to request admission to a particular VLAN for multicast purposes.
Gateway
A local device, usually a router, that connects hosts on a local network to other networks.

Generic Attribute Registration Protocol
GARP provides a generic attribute dissemination capability that is used by participants in GARP
Applications (called GARP Participants) to register and de-register attribute values with other GARP
Participants within a Bridged LAN. The definition of the attribute types, the values that they can carry, and
