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 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.
