MSS
The Maximum Segment Size (MSS) defines the maximum number
of bytes that can be used as user data in a TCP segment. The MSS
must be smaller than the Maximum Transmission Unit (MTU) to
avoid fragmenting the IP packets.
MSS clamping
MSS clamping reduces the Maximum Segment Size (MSS) in order
to connect networks with different Maximum Transmission Units
(MTU).
MTU
The Maximum Transmission Unit (MTU) is the largest possible data
unit that can be transmitted over a physical line.
Multicast
With a multicast, data packets are sent from one point to particular
subscribers in a network. In IPv4 this is controlled via the address
range 224.0.0.0 to 239.255.255.255 and the IGMP protocol, while in
IPv6 it is controlled by ff00::/8 addresses and ICMPv6.
Multifrequency code
dialling method
The multifrequency code dialling method, also known as tone dial-
ling, MFV, MFC and DTMF, is a signalling method for automatic
telephone routing. Key inputs are represented by overlaid, sinusoid-
al signals. See also Pulse dialling.
Multilink
With multilink, multiple interfaces (PPP, PPPoE, ...) are combined
into a single virtual connection in order to increase the total band-
width available.
Multiple subscriber
number
Multiple subscriber numbers are the individual phone numbers in the
ISDN point-to-multipoint connection.
Music on Hold
The term Music On Hold (MOH) refers to automated announce-
ments or hold music on the PBX.
Music on hold
See Music on hold.
MWI
The Message Waiting Indicator (MWI) signals that a new message
is available.
NAPT
Network Address Port Translation (NAPT) is another term for PAT.
See PAT.
NAT
Network Address Translation (NAT) is used to replace the source
and destination IP addresses of a data packet with others. This en-
ables different networks to be connected to one another. See also
PAT.
NBNS
Like DNS, NetBIOS Name Service (NBSN) is used in centralised
name resolution. See also WINS and DNS.
