MSTI
It may be necessary to have different topologies for different VLANs, for load-sharing or other
purposes. MSTP enables the grouping of multiple VLANs with the same topology
requirements into one MST instance (MSTI). Instances are not supported in STP or RSTP, so
those two versions have the same spanning-tree in common for all of the VLANs.
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
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
