DVMRP Distance Vector Multicast Routing Protocol — DVMRP (RFC 1075) is an
Internet routing protocol that provides multicast routing. It supports IP
multicast routing by broadcasting data to each router in an
internetwork when users join or leave multicast groups.
dynamic route Dynamic routes are IP routes learned using a routing information
protocol, such as OSPF or RIP.
firewall A combination of specifically configured network hardware and
software products that limit access to the network by unauthorized
individuals from outside the firewall. For example, a firewall can enforce
an access control policy between an internal network and the Internet.
flash EPROM Erasable Programmable Read-Only Memory. Programmable Read-Only
Memory Technology providing nonvolatile storage that can be
electrically erased in the circuit and reprogrammed.
flat network A network that consists of a single backbone domain. The connections
between devices are only at the Layer 2 level, and do not contain
routers.
host An IP end-station, such as a UNIX workstation, a personal computer or
a network-connected device.
GARP Generic Attribute Registration Protocol — GARP is a system outlined by
the IEEE 802.1D standard that allows endstations in a network to
register that they would like to receive traffic with certain attributes.
gateway A device that can interconnect networks with different, incompatible
communications protocols.The gateway performs a layer-7
protocol-conversion to translate one set of protocols to another (for
example, from TCP/IP to SNA or from TCP/IP to X.25). A gateway
operates at Open Systems Interconnection (OSI) layers up through the
Session Layer.
GVRP GARP VLAN Registration Protocol — GVRP is a specific use of GARP
that allows endstations to register that they would like to receive traffic
for certain VLANs.
HTTP HyperText Transfer Protocol — HTTP is a protocol used for transferring
text and images over an intranet or the Internet.
