MLD
MLD is an acronym for Multicast Listener Discovery for IPv6. MLD is used by IPv6 routers to discover multicast
listeners on a directly attached link, much as IGMP is used in IPv4. The protocol is embedded in ICMPv6 instead of
using a separate protocol.
MVR
Multicast VLAN Registration (MVR) is a protocol for Layer 2 (IP)-networks that enables multicast-traffic from a source
VLAN to be shared with subscriber-VLANs. The main reason for using MVR is to save bandwidth by preventing
duplicate multicast streams being sent in the core network, instead the stream(s) are received on the MVR-VLAN and
forwarded to the VLANs where hosts have requested it/them (Wikipedia).
N
NAS
NAS is an acronym for Network Access Server. The NAS is meant to act as a gateway to guard access to a
protected source. A client connects to the NAS, and the NAS connects to another resource asking whether
the client's supplied credentials are valid. Based on the answer, the NAS then allows or disallows access to
the protected resource. An example of a NAS implementation is IEEE 802.1X.
NetBIOS
NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate
computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN).
The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to
a different host name, provides the session and transport services described in the Open Systems
Interconnection (OSI) model.
NFS
NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as
though they are local file systems.
NFS allows the system administrator to store resources in a central location on the network, providing
authorized users continuous access to them, which means NFS supports sharing of files, printers, and other
resources as persistent storage over a computer network.
NTP
NTP is an acronym for Network Time Protocol, a network protocol for synchronizing the clocks of computer
systems. NTP uses UDP (datagrams) as transport layer.
