MD5
MD5 is an acronym for Message-Digest algorithm 5. MD5 is a message digest algorithm, used
cryptographic hash function with a 128-bit hash value. It was designed by Ron Rivest in 1991. MD5
is officially defined in RFC 1321 - The MD5 Message-Digest Algorithm.
Mirroring
For debugging network problems or monitoring network traffic, the switch system can be configured
to mirror frames from multiple ports to a mirror port. (In this context, mirroring a frame is the same
as copying the frame.)
Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.
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 MLD 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).
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.
