Abstract

A services definition language for seamlessly creating and maintaining services over a network service reduces deployment time, cost, and maintenance, and increases reliability. An executable element generator is operable to process module scripts, such as an XML (Extensible Markup Language) script, recognized across the execution environment. Each module script describes a network element, service, or subscription. A plurality of available services are defined, in which each of the available services corresponds to one or more of the module scripts. A script processor interprets the module script and provides it to executable element generators conversant in the script language, which process the module scripts via a GUI to produce executable objects. A service provisioning engine is operable to execute the executable objects for providing the corresponding service via the network.

Claims

1. A services definition language, comprising:

a predefined set of attributes, each of the attributes applicable to at least one network entity, the attributes operable to be selectively identified by an operator interface to correspond to a particular network entity;

a plurality of elements, each of the elements adapted to include at least one attribute; and

a hierarchical rule structure indicative of the arrangement of elements;

the attributes adapted to receive values corresponding to the operation of the network entity.

2. The language of claim 1 wherein the operator interface is a module builder.

3. The language of claim 1 wherein the hierarchical rule structure is a Document Type Definition (DTD).

4. The language of claim 1 further comprising tags, each tag including at least one attribute and at least one value.

5. The language of claim 1 wherein the language is further adapted to be processed by a metalanguage processer, the metalanguage processor conforming to the hierarchical rule structure.

6. A language for defining and deploying services comprising:

a plurality of elements, each of the elements operable for performing a predetermined action;

a plurality of behaviors, each of the behaviors having a set of actions and at least zero attributes;

at least one class, each of the classes including at least one behavior and corresponding to a service entity; and

at least one task, each of the tasks adapted to execute a behavior.

7. The language of claim 6 further comprising a flow, the flow having a plurality of states, each of the states operable to execute behaviors, tasks, and other flows.

8. The language of claim 6 wherein the elements further comprise low-level programming constructs.

9. The language of claim 6 wherein the behaviors are operable to define the functionality of a service entity.

10. The language of claim 6 wherein the classes are operable to model a particular service entity for providing a particular service.

11. The language of claim 6 wherein the tasks are operable to be executed concurrently.

12. A computer program product having computer program code for providing services via a services operating system comprising:

computer program code for providing a module builder operable to generate module scripts, the module scripts indicative of a service entity;

computer program code for providing a script engine, the script engine operable to process the module scripts to identify attributes of the corresponding service entity;

computer program code for providing at least one executable element generator, the executable element generator responsive to the script engine;

computer program code for generating, via the executable element generator, executable objects corresponding to the service entity by assigning values to the attributes;

computer program code for storing the executable objects in a knowledge base; and

computer program code for deploying the executable objects for providing services.
