LDAP
The LDAP protocol (Lightweight Directory Access Protocol) is a directory
access protocol based on TCP/IP (Transmission Control Protocol/Internet
Protocol). On the Internet and in intranets, it has become the standard
solution for accessing network directory services for databases, e-mail,

M
MAC
The MAC address (Media Access Control) is the hardware address of each
individual network adapter, and is used for unique identification of the
device in the network. The MAC address is assigned to the data link layer
(layer two) of the OSI model. To connect the data link layer with the
network layer in the case of Ethernet, for example, the ARP protocol
(Address Resolution Protocol) is used.
MIB
A MIB (Management Information Base) is a kind of table, which defines
which information can be called up. The MIB of an agent (host, router,
access point, etc.) is specified by the manufacturer. The task of this MIB is to

MOH

whilst a call is on hold.
MPPE
The MPPE protocol (Microsoft Point-to-Point Encryption) is used to encrypt
PPTP data packets. For this purpose, the MPPE protocol offers a 40-bit key
length (international version) and a 128-bit key length (US version). Data
encoding is based on RSA 4 Stream Cipher (RC4). In the case of the 128-bit
key, a 64-bit part of the key is changed for each new session to raise
