MISO
Multiple Input Single Output. An antenna technology for wireless communica-
tions in which multiple antennas are used at the source (transmitter). The
antennas are combined to minimize errors and optimize data speed. The
destination (receiver) has only one antenna.
MLD
Multicast Listener Discovery. A component of the IPv6
suite. It is used by
IPv6 routers for discovering multicast listeners on a directly attached link.
MPDU
MAC Protocol Data Unit. MPDU is a message exchanged between MAC
entities in a communication system based on the layered OSI model.
MPLS
Multiprotocol
Label Switching. The MPLS protocol speeds up and shapes
network traffic flows.
MPPE
Microsoft Point
-to-Point Encryption. A method of encrypting data transferred
across PPP-based dial-up connections or PPTP-based VPN connections.
MS
-CHAP
Microsoft Challen
ge Handshake Authentication Protocol. MS-CHAP is Pass-
word
-based, challenge-response, mutual authentication protocol that uses
MD4 and DES encryption.
MS
-CHAPv1
Microsoft Challenge Handshake Authentication Protocol version 1. MS
-
CHAPv1 extends the user
authentication functionality provided on Windows
networks to remote workstations. MS
-CHAPv1 supports only one-way au-
thentication.
MS
-CHAPv2
Microsoft Challenge Handshake Authentication Protocol version 2. MS
-
CHAPv2 is an enhanced version of the MS
-CHAP protocol that supports
mutual authentication.
MSS
Maximum Segment Size. MSS is a parameter of the options field in the TCP
header that specifies the largest amount of data, specified in bytes, that a
computer or communications device can receive in a single TCP segment.
MSSID
Mesh Service Set Identifier. MSSID is the SSID used by the client to access
a wireless mesh network.
MSTP
Multiple Spanning Tree Protocol. MSTP configures a separate Spanning
Tree for each VLAN group and blocks all but one of th
e possible alternate
paths within each spanning tree.
MTU
Maximum Transmission Unit. MTU is the largest size packet or frame speci-
fied in octets (eight
-bit bytes) that can be sent in networks such as the Inter-
net.
MU
-MIMO
Multi
-User Multiple-Input Multiple-Output. MU-MIMO is a set of multiple-input
and multiple
-output technologies for wireless communication, in which users
or wireless terminals with one or more antennas communicate with each
other.
MVRP
Multiple VLAN Registration Protocol. MVRP is a Laye
r 2 network protocol
used for automatic configuration of VLAN information on switches.
mW
milliWatts. mW is 1/1000 of a Watt. It is a linear measurement (always posi-
tive) that is generally used to represent transmission.
NAC
Network Access Control. NAC i
s a computer networking solution that uses a
set of protocols to define and implement a policy that describes how devices
can secure access to network nodes when they initially attempt to connect to
a network.
NAD
Network Access Device. NAD is a
device that automatically connects the
user to the preferred network, for example, an AP or an Ethernet switch.
