Term Definition
MEP
An acronym for Maintenance Entity Endpoint and is an endpoint in a
Maintenance Entity Group (ITU-T Y.1731).
MD5
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
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 the multicast streams. (Wikipedia)
N
NAS
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
An acronym for Network Basic Input/Output System. It is a program that
permits 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
An acronym for Network File System. It permits hosts to mount partitions on a
remote system and use as a local file systems.
NFS enables the system administrator to store resources in a central location
on the network, providing authorized users continuous access, which means
NFS supports sharing of files, printers, and other resources as persistent
storage over a computer network
