Application Manager
A server within a network that is responsible for establishing and managing subscriber sessions associated with a specific application.
Application Programming Interface
An interface with commands, possibly routines and/or macros, provided by an operating system or an add-on for an operating system (that support network use, for example). Application programs can use this interface to tell the operating system to perform specific actions.
Basic Input-Output System
Firmware on the CPU blade that is executed prior to executing an OS.
Broadband Remote Access Server
Routes traffic to and from broadband remote access devices such as DSL multiplexers. The locations where policy management and DQoS functions occur. Also see BNG.
Complementary Metal Oxide Semiconductor
CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor.
Configuration Management Platform
A centralized management interface to create policies, maintain policy libraries, configure, provision, and manage multiple distributed MPE policy server devices, and deploy policy rules to MPE devices. The CMP has a web-based interface.
Cable Modem Termination System
An edge device connecting to subscribers' cable modems in a broadband network. A CMTS device can function as a PCEF device; see PCEF.
Equipment used by cable companies to provide high speed data services to cable subscribers.
Domain Name System
A system for converting Internet host and domain names into IP addresses.
Dynamic Quality of Service
A COPS-based protocol that is part of the Packet Cable standards used to communicate between a CMS and a CMTS for setting up voice calls. An MPE device can be inserted between these two entities to apply additional policy rules as sessions are established.
Full Address Based Resolution
Provides an enhanced DSR routing capability to enable network operators to resolve the designated Diameter server addresses based on individual user identity addresses in the incoming Diameter request messages.
Management Information Database
A database of network management information that is used and maintained by the SNMP protocol.
Multimedia Policy Engine
A high-performance, high-availability platform for operators to deliver and manage differentiated services over high-speed data networks. The MPE includes a protocol-independent policy rules engine that provides authorization for services based on policy conditions such as subscriber information, application information, time of day, and edge resource utilization.
Messages Per Second
A measure of a message processor’s performance capacity. A message is any Diameter message (Request or Answer) which is received and processed by a message processor.
Mail Transfer Agent (or Message Transfer Agent)
Email server software that transfers electronic mail messages from one computer to another.
Network Configuration Management Platform
The NW-CMP server configures Network tier objects. Examples of Network tier objects are policies, network elements, and configuration templates.
Object Identifier
An identifier for a managed object in a Management Information Base (MIB) hierarchy. This can be depicted as a tree, the levels of which are assigned by different organizations. Top level MIB OIDs belong to different standard organizations. Vendors define private branches that include managed objects for their own products.
QBus Platform
Software that provides an execution environment for Java-based applications, providing common interfaces into databases, event logging, SNMP, and cluster state.
Range Based Address Resolution
A DSR enhanced routing application which allows you to route Diameter end-to-end transactions based on Application ID, Command Code, Routing Entity Type, and Routing Entity address ranges.
System Configuration Management Platform
The S-CMP servers configure System tier objects. System tier objects are MPE and MRA devices.
Simple Network Management Protocol.
An industry-wide standard protocol used for network management. The SNMP agent maintains data variables that represent aspects of the network. These variables are called managed objects and are stored in a management information base (MIB). The SNMP protocol arranges managed objects into groups.
Transmission Control Protocol
A connection-oriented protocol used by applications on networked hosts to connect to one another and to exchange streams of data in a reliable and in-order manner.
Virtual IP Address
Virtual IP is a layer-3 concept employed to provide HA at a host level. A VIP enables two or more IP hosts to operate in an active/standby HA manner. From the perspective of the IP network, these IP hosts appear as a single host.
