Preliminary Spec. ver
1.4
•
LAN - Local Area Network.
•
Little endian - The byte at memory address 0 contains the least-significant bits. Used by Intel x86, DEC Vax,
and DEC PDP-11.
•
LLC - Logical Link Control layer of LAN CSMA/CD. The upper half of the OSI (which see) reference model data
link layer, between the MAC and the network layer.
•
Locally administered address - An Ethernet address whose second bit transmitted, used to distinguish between
locally or globally administered addresses, is set to 1, indicating a locally administered address. If an address is
to be assigned globally (or U, universal), this bit shall be set to 0. Note that for the broadcast address, this bit is
also a 1.

•
MAC - Media Access Control layer of LAN CSMA/CD. The lower half of the OSI (which see) reference model
data link layer, between the LLC and the PLS.
•
MAU - Medium Attachment Unit layer of LAN CSMA/CD. See OSI.
•
MDI - Medium Dependent Interface layer of LAN CSMA/CD. The part of the MAU that connects the PMA to the
medium. See OSI.
•
MII - Media Independent Interface. A four-bit-wide interface between a reconciliation layer and the PLS. The
reconciliation layer connects to the MAC using the existing 802.3 MAC-PLS interface.
•
Minimum frame length - 64 bytes (512 bits). Note that this does not include the preamble and the start frame
delimiter.
•
Multicast address - An Ethernet destination address whose first bit transmitted, used to identify it either as an
individual or as a group address, is 1, indicating that the address field contains a group address that identifies
none, one or more, or all of the stations connected to the local area network. The first byte of a multicast
address is odd, for example, 01-00-00-00-00-00. There are two kinds of multicast address: (a) Multicast-group
address. An address associated by higher-level convention with a group of logically-related stations. (b)
Broadcast address. A distinguished, predefined multicast address that always denotes the set of all stations on
a given local area network.
•
Multicast-group address - An address associated by higher-level convention with a group of logically-related
stations. This is one of two kinds of multicast address, the other being the broadcast address, ff-ff-ff-ff-ff-ff.
•
NDIS - Network Driver Interface Specification for a generic device driver, independent of protocol or hardware.
•
Network acquisition time - If the DTE transmits for a period exceeding the net acquisition time without detecting
a collision, then the DTE is said to have acquired the network. The DTE will send the remainder of its frame
without the possibility of having a collision in a correctly operating network. By this time, all DTEs in the network
have detected network activity and are deferring to it.... For example, the network acquisition time on a single-
segment 10BASE5 network of 500-meter length is approximately 108 bit times.
2
Also called round trip delay.
•
NIC - Network Interface Controller or Card. Also Network Information Center, at SRI International, which
assigns a network a class field (A, B, or C) and a unique network ID field of the 32-bit TCP/IP addresses.
•
OC1 - 51.84 Mbit/s Optical Carrier 1, SONET Synchronous Transport Signal STS-1. 28 DS1 signals or one
DS3.
•
OC3 - 155.52 Mbit/s Optical Carrier 3, SONET Synchronous Transport Signal STS-3. Three byte-interleaved
STS-1 signals.
