IEEEInstitute of Electrical
and Electronics Engineers.
Professional organization whose activities include the development
of communications and network standards. IEEE LAN standards are the
predominant LAN standards today. |
IEEE 802.1IEEE specification that describes an
algorithm that prevents bridging loops by creating a spanning tree.
The algorithm was invented by Digital Equipment Corporation. The
Digital algorithm and the IEEE 802.1 algorithm are not exactly the
same, nor are they compatible. |
IEEE 802.12IEEE LAN standard that specifies the
physical layer and the MAC sublayer of the data link layer. IEEE
802.12 uses the demand priority media-access scheme at 100 Mbps over
a variety of physical media. |
IEEE 802.2IEEE LAN protocol that specifies an
implementation of the LLC sublayer of the data link layer. IEEE
802.2 handles errors, framing, flow control, and the network layer
(Layer 3) service interface. Used in IEEE 802.3 and IEEE 802.5 LANs. |
IEEE 802.3IEEE LAN protocol that specifies an
implementation of the physical layer and the MAC sublayer of the
data link layer. IEEE 802.3 uses CSMA/CD access at a variety of
speeds over a variety of physical media. Extensions to the IEEE
802.3 standard specify implementations for Fast Ethernet. Physical
variations of the original IEEE 802.3 specification include 10BASE2,
10BASE5,
10BASEF,
10BASE-T,
and 10Broad36.
Physical variations for Fast
Ethernet include 100BASE-T,
100BASE-T4,
and 100BASEX. |
IEEE 802.3iPhysical variation of the original
IEEE 802.3 specification that calls for using Ethernet type
signaling over twisted pair networking media. The standard sets the
signaling speed at 10 megabits per second using a baseband signaling
scheme transmitted over twisted pair cable employing a star or
extended star topology. |
IEEE 802.4IEEE LAN protocol that specifies an
implementation of the physical layer and the MAC sublayer of the
data link layer. IEEE 802.4 uses token-passing access over a bus
topology and is based on the token bus LAN architecture. |
IEEE 802.5IEEE LAN protocol that specifies an
implementation of the physical layer and MAC sublayer of the data
link layer. IEEE 802.5 uses token passing access at 4 or 16 Mbps
over STP cabling and is similar to IBM Token Ring. |
IEEE 802.6IEEE MAN specification based on DQDB
technology. IEEE 802.6 supports data rates of 1.5 to 155 Mbps. |
IETFInternet Engineering
Task Force. Task force consisting
of over 80 working groups responsible for developing Internet
standards. The IETF operates under the auspices of ISOC. |
IGMPInternet Group
Management Protocol. Used by IP
hosts to report their multicast group memberships to an adjacent
multicast router. |
IGPInterior Gateway
Protocol. Internet protocol used
to exchange routing information within an autonomous system.
Examples of common Internet IGPs include IGRP, OSPF, and RIP. |
IGRPInterior Gateway Routing
Protocol. IGP developed by Cisco
to address the problems associated with routing in large,
heterogeneous networks. |
infraredElectromagnetic waves whose frequency
range is above that of microwaves, but below that of the visible
spectrum. LAN systems based on this technology represent an emerging
technology. |
interface1. Connection between two systems or
devices. 2. In routing terminology, a network connection. 3. In telephony, a shared boundary defined by common physical interconnection characteristics, signal characteristics, and meanings of interchanged signals. 4. The boundary between adjacent layers of the OSI model. |
IPInternet Protocol.
Network layer protocol in the TCP/IP stack offering a connectionless
internetwork service. IP provides features for addressing,
type-of-service specification, fragmentation and reassembly, and
security. Documented in RFC 791. | |
IP address1.) 32-bit address assigned to hosts
using TCP/IP. An IP address belongs to one of five classes (A, B, C,
D, or E) and is written as 4 octets separated with periods (dotted
decimal format). Each address consists of a network number, an
optional subnetwork number, and a host number. The network and
subnetwork numbers together are used for routing, while the host
number is used to address an individual host within the network or
subnetwork. A subnet mask is used to extract network and subnetwork
information from the IP address. Also called an Internet address.
2.) Command used to establish the logical network address of this
interface. | |
IP multicastRouting technique that allows IP
traffic to be propagated from one source to a number of destinations
or from many sources to many destinations. Rather than sending one
packet to each destination, one packet is sent to a multicast group
identified by a single IP destination group address |
ISDNIntegrated Services
Digital Network. Communication
protocol, offered by telephone companies, that permits telephone
networks to carry data, voice, and other source traffic |
IS-ISIntermediate
System-to-Intermediate System.
OSI link-state hierarchical routing protocol based on DECnet Phase V
routing whereby ISs (routers) exchange routing information based on
a single metric to determine network topology. |
