MIB Management Information Base. A MIB is a formal description of a set of network objects that can
be managed using SNMP. The format of the MIB is defined as part of the SNMP. (All other MIBs
are extensions of this basic management information base.) MIB-I refers to the initial MIB
definition; MIB-II refers to the current definition.
There are MIBs (or MIB extensions) for each set of related network entities that can be managed.
For example, there are MIB definitions specified in the form of domain name system (DNS), Fiber
Distributed-Data Interface, and RS-232C network objects. Product developers can create and
register new MIB extensions.
WebGate OSN WebGate. A collection of OSN-based traffic management features, including a WAP
Gateway, URL Management, Policy-Based Routing and Selective Forward Proxying.
milliseconds milliseconds, or ms, equals one-thousandth of a second.
MIME Multipurpose Internet Mail Extensions, a specification for encoding binary messages so that they
can be sent over the Internet mail system as 7-bit ASCII. Support for MIME allows e-mail clients
to send and receive graphics, audio, and video files over the Internet.
Mobile Station The Mobile Station (MS) is the subscriber’s access device to the wireless network (for example, a
cellular phone, personal digital assistant, or wireless-enabled terminal).
MSC Mobile Switching Center. The MSC is an operations center that connects the landline PSTN
system to the mobile phone system. It is also responsible for compiling call information for billing
and handing off calls from one cell to another. Sometimes called a Mobile services Switching
Center.
MSISDN Mobile Station Integrated Services Digital Network. The telephone number of a GSM cellphone.
The MSISDN is stored in the SIM card inside the phone. See GSM.
MVNO Mobile Virtual Network Operator. An MVNO is a reseller of wireless services. MVNOs do not
own licensed spectrum and typically do not have any of their own wireless network infrastructure.
Like landline telephone resellers, they sell service under their own brand name but use the facilities
of existing carriers.
MTU Maximum Transmission Unit. A link layer restriction on the maximum number of bytes of data in
a single transmission (that is, frame, cell, packet, depending on the terminology).
NAP Network Access Point. The location for interconnection of Internet Service Providers in the United
States for the exchange of packets.
NAT Network Address Translation. The process of converting IP addresses in an intranet (or stub
domain) and Internet IP addresses. NAT makes it possible to use a large number of addresses
within a stub domain without depleting the available IP addresses.
node An addressable point on a network. A node can connect a computing system, a terminal, or various
other peripheral devices to the network.
OID Object Identifier. OIDs are strings of numbers allocated in a hierarchical manner. For example, the
authority for “1.2.3” is the only one that can say what “1.2.3.4” means. The formal definition of
OIDs comes from ITU-T recommendation X.208 (ASN.1).
