IETF Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.
IFM See Intelligent Flow Management.
IGMP Internet Group Management Protocol. An IP-based multicast filtering
system that allows endstations to register that they would like to
receive traffic from certain multicast groups.
Intelligent Flow
Management
Intelligent Flow Management. A means of holding packets back at the
transmit port of the connected endstation. Prevents packet loss at a
congested switch port. Also known as IFM.
Intelligent Switching
Mode
A packet forwarding mode, where the Switch monitors the amount of
error traffic on the network and changes the method of packet
forwarding accordingly.
IP Internet Protocol. IP is a layer 3 network protocol that is the standard
for sending data through a network. IP is part of the TCP/IP set of
protocols that describe the routing of packets to addressed devices.
IPX Internetwork Packet Exchange. IPX is a layer 3 and 4 network protocol
designed for networks that use Novell
® Netware ® .
IP address Internet Protocol address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated
with periods (full-stops), and is made up of a network section, an
optional subnet section and a host section.
LAN Local Area Network. A network of endstations (such as PCs, printers,
servers) and network devices (hubs and switches) that cover a relatively
small geographic area (usually not larger than a floor or building). LANs
are characterized by high transmission speeds over short distances (up
to 1000m).
latency The delay between the time a device receives a packet and the time the
packet is forwarded out of the destination port.
line speed See baud.
