Abstract
In a method of controlling a computer in an object-oriented environment, descriptors are implemented as an object oriented class to store meta information on other classes in the system.
Description
~ . 02200 009 OBJECT ORIENTED PROGRAMMING METHOD
This invention relates to a method of controlling a computer in an object-oriented environment, for example in a system for monitoring service level agreements in telecommunications networks.
Our co-pending application of even date describes a system for m~n~gin~ service level agreements in a data network to ensure compliance with customer commitments.
Requirements change over time and a competitive system should have the capability of permitting new capabilities to be added quickly. When new capabilities are added, specific areas of the system must be modified to accommodate them. It is desirable to limit the impact of introducing the new capabilities in these areas in order to reduce the development time and risks associated with introducing problems (bugs ) in those areas.
Two areas are especially prone to be impacted when new capabilities are added. These are the user security management module and the service configuration module. When new capabilities are added, users of the system must be given permission to use these capabilities. In addition, when new service component types or service level agreement thresholds must be supported, the service configuration module is impacted.
An object of the invention is to facilitate the addition of new capabilities to a service management system.
According to the present invention there is provided a method of controlling a computer in an object-oriented environment wherein descriptors implemented as an object oriented class are used to store meta information on other classes in the system.
The base descriptor class provides a template where unique identifiers, names and descriptions are stored. Derived classes are used to define additional qualities for specific descriptors. The intent behind the Descriptor concept is to minimi7e the impact of adding new functionality on critical parts of the system.
Derived descriptor classes can be implemented for service entities, functions, statistics, Service Level Agreement thresholds, operations, service components, etc...
The invention will now be described in more detail, by way of example only, withreference to the accompanying drawings, in which:-~ 0~200 009 Figure 1 illustrates the different types of descriptors that are employed;
Figure 2 shows ho descriptors are used to dynamically add new capabilities to the system;and Figure 3 shows the top layer object model.
Figure 1 shows the types of descriptors that are provided in a typical system for m:~n~ing service level agreements. There is a top level descriptor, and derived descriptors relating to various aspects of the system.
The top level descriptor stores meta information on entities. The base class provides a template where unique Ids, names and descriptions are stored. The derived classes define additional qualities for specific descriptors.
In a service level management system, new service level agreement thresholds can be added to the system without modifying the service profile code. For example:
Export Control: Public Cardinalify n Hierarchy:
Superclasses None Private Interface:
Attributes:
type: short The descriptor uniquely identifies the descriptor record attached to a specific class Name:char[200]
The descriptor name is the unique name of a descriptor Description :char[200]
The description is a brief summary of the purpose of the descriptor State Machine: No ~ ~ 02200 009 Concurrency Sequential Persistence Persistent Figure 2 illustrates how descriptors are used to dynamically add new capabilities to the system. As new entities or operations on entities are defined and implemented, new entity operation descriptors are defined and added. When these descriptors are added, the user management module becomes aware of these capabilities. The user management module is used to give/deny access to specific parts of the system.
Each instance of a descriptor sources its information from a specific row in a relational database table. The following table illustrates the instance data associated with the service component descriptors for use in a system for m~n~ging service level agreements in a telecommunications network.

New descriptors are added for SLA thresholds, and statistics.
New valid operations instances are created for ATM UNI. No software is required to change in the user / security management module.
New service profiles can be created using ATM UNI without any modifications to the software in this critical area.
New services can be configured with ATM UNI service components assigned to them.
Within the configurator, the only software modifications required are new screens to view details associated with the ATM UNI.
