The Q3ADE Core

The Q3ADE Core forms the "highway" of information mediation inside and between Q3ADE Applications.

It provides a very advanced object broker functionality that enables the information integration across very different technologies like CORBA, CMIP and SNMP.

Information mediated between two technologies are converted into a common information message format called Q3 (hence the Q3 in Q3ADE!) by the technology gateway components, before it is mediated via the "Common Management Information Bus". The receiver maybe any relevant application component or another technology gateway, which translates it into whatever technology specific format.

Information representing events, like alarms are likewise translated into a uniform Q3 Alarm message format and forwarded relevant application services like the Fault Management Service, where it is stored and correlated with other alarm events.

The Q3ADE Core presents all management information as one huge virtual information store, which may be queried by means of a high level object oriented query language (CMIS). The same query may even span across multiple equipments based on different interface technologies.

The Q3ADE Core also provides a highly integrated script tool, which enables script based tailoring of practically any part of the Q3ADE Core and the objects in the MIB and hence a wide range of Q3ADE 3G Functionality.

Scalability through multi-threading and multi-processing

The Q3ADE Core enables scalability through efficient utilization of multi-processor and multi-core architectures. The technology behind this is called "multi-threading", which enables parallel processing and pipeline (bucket-brigade) processing. In other words, a Q3ADE process may perform several tasks at the same time and hence keep several CPU's busy.

The Q3ADE 3G Cluster function incresases the scalability further by enabling several Q3ADE 3G processes on the same Host to act as one application. Any number of processes (limited by license and OSS) may run on  the same host to manage really big systems or very large transaction volumes, e.g. activation applications.

Is this not enough? Then you may go even further, by distributing the management task between several interconnected Q3ADE 3G servers:

The Distributed TMN Architecture of Q3ADE

The QADE Core enables Q3ADE 3G components in different Q3ADE process (whether Q3ADE 3G or other Q3ADE based applications) to interact across any TCP/IP or ISO NSAP based network. This enables you to interconnect several Q3ADE 3G platforms to form huge distributed application networks, transparent to the user of Q3ADE 3G. The capacity of Q3ADE 3G may be scaled practically endlessly by establishing a distributed network of Q3ADE 3G Servers.

Some of the Q3ADE 3G Servers may be located close to the equipment (or even embedded in it) to perform information processing near the information source, e.g. perform event correlation or periodical information collection/aggregation. Some of the Q3ADE 3G Servers may be located close to the users, to enable fast access to the information.

Object Persistency & Database

The information processing paradigm of Q3ADE is extensively object oriented. Practically any type and amount of information may be processed and stored seamlessly by Q3ADE.

To enable this massive flexibility, the Q3ADE core includes a persistent object data base (PODB), which is able to store any data object generically and transparently to the application code. The PODB may be queried using an object-oriented SQL-like query language (CMIS).

The capacity of the PODB in terms of number of object instances is in the range 10^18 ( a 1 followed by 18 zeros). The capacity in terms of bytes is in the range 10^25 bytes. If that is not enough, then several Q3ADE processes may interact to form a single virtual object store, each with that capacity.

Integration with 3'rd party Management Applications

Q3ADE 3G provides three kinds of open interfaces that allows you to connect to/from 3'rd party Telecom Management OSS' based on Q3/CMIP, CORBA/IIOP and XML/HTTP.

Furthermore, Q3ADE 3G may access any ODBC enabled database.
