MAC AddressStandardized data link layer
address that is required for every port or device that connects to a
LAN. Other devices in the network use these addresses to locate
specific ports in the network and to create and update routing
tables and data structures. MAC addresses are 6 bytes long and are
controlled by the IEEE. Also known as a hardware address, a MAC-layer
address, or a physical address. | |
MANMetropolitan-area
network. Network that spans a metropolitan area. Generally,
a MAN spans a larger geographic area than a LAN, but a smaller
geographic area than a WAN | |
MBONEMulticast backbone.
The multicast backbone of the Internet. MBONE is a virtual multicast
network composed of multicast LANs and the point-to-point tunnels
that interconnect them. | |
Mbpsmegabits per second. | |
MD5Message Digest 5.
Algorithm used for message authentication in SNMP v.2. MD5 verifies
the integrity of the communication, authenticates the origin, and
checks for timeliness. | |
meshNetwork topology in which
devices are organized in a manageable, segmented manner with many,
often redundant, interconnections strategically placed between
network nodes. | |
modemModulator-demodulator.
Device that converts digital and analog signals. At the source, a
modem converts digital signals to a form suitable for transmission
over analog communication facilities. At the destination, the analog
signals are returned to their digital form. Modems allow data to be
transmitted over voice-grade telephone lines. |
MTUMaximum transmission
unit. Maximum packet size, in bytes, that a particular
interface can handle. |
multicastSingle packets copied by the
network and sent to a specific subset of network addresses. These
addresses are specified in the destination address field. |
multicast addressSingle address that refers
to multiple network devices. Synonymous with group address. |
multicast groupDynamically determined group
of IP hosts identified by a single IP multicast address. | |
multicast routerRouter used to send IGMP
query messages on their attached local networks. Host members of a
multicast group respond to a query by sending IGMP reports noting
the multicast groups to which they belong. The multicast router
takes responsibility for forwarding multicast datagrams from one
multicast group to all other networks that have members in the
group. |
multicast serverEstablishes a one-to-many
connection to each device in a VLAN, thus establishing a broadcast
domain for each VLAN segment. The multicast server forwards incoming
broadcasts only to the multicast address that maps to the broadcast
address. | |
multihomed hostHost attached to multiple
physical network segments in an OSI CLNS network. |
multilayer switchSwitch that filters and
forwards packets based on MAC addresses and network addresses. A
subset of LAN switch. | |
T1Digital WAN carrier facility. T1
transmits DS-1-formatted data at 1.544 Mbps through the
telephone-switching network, using AMI or B8ZS coding. Compare with E1. | |
T3Digital WAN carrier facility. T3
transmits DS-3-formatted data at 44.736 Mbps through the telephone
switching network. Compare with E3.
|
TCP/IPTransmission Control
Protocol/Internet Protocol. Common
name for the suite of protocols developed by the U.S. DoD in the
1970s to support the construction of worldwide internetworks. TCP
and IP are the two best-known protocols in the suite. |
TDMTime-division
multiplexing. Technique in which
information from multiple channels can be allocated bandwidth on a
single wire based on preassigned time slots. Bandwidth is allocated
to each channel regardless of whether the station has data to
transmit. | |
telcoAbbreviation for telephone company. |
