Abstract

A communication network control system includes facilities for data driven control of components attached to the network The network has an overall control function and each component has an individual control function. Common component control functions can be controlled via the overall control function straightaway. Uncommon component control functions are controlled via translation of subfunctions within the overall control function. Such translations are effected as required based upon information regarding individual component needs, which information is stored in a data model where it may be accessed and subsequently interpreted as part of the overall control function.

Claims

1. A control system for a communication network including a plurality of components exhibiting at least some common behavior, said communication network having a network control function, certain ones of said plurality of components having an individual control function exhibiting uncommon control behavior, said control system comprising:

first means for controlling network operations using said network control function by transmitting control orders to effectuate the establishment of a network communications connection between at least two of the components in accordance with the common behaviors of the connected components; and

second means for controlling network operations using said network control function comprising;

a data model including information regarding uncommon behavior of the individual control functions of said plurality of components;

means for accessing said data model to extract information as to uncommon behavior of said plurality of components;

means for interpreting the information extracted from said data model to tailor the transmitted control orders to account for the uncommon behavior of the individual control function for a given one of the components and effectuate the establishment of a network communications connection between that given component having uncommon behavior and another one of the components in the network.

2. A control system as recited in claim 1, wherein said control orders comprise orders to perform network communications connect and disconnect operations.

3. A control system as recited in claim 2, wherein said control orders further comprise orders to perform a network communications release operation.

4. A control system as recited in claim 3, wherein said control orders further comprise orders to perform a network communications reserve operation.

5. A control system as recited in claim 1, wherein said data model comprises translation information corresponding to said control orders.

6. A control system as recited in claim 5, wherein said translation information comprises a list of tailored control orders for the uncommon behaviors corresponding to the control orders for the common behaviors.

7. A method for data driven control of a plurality of components forming a communication network, said plurality of components exhibiting at least some common behavior, said communication network having a network control function, certain ones of said plurality of components having an individual control function exhibiting uncommon behavior, said method comprising the steps of:

first controlling of network operations using said network control function by transmitting control orders to effectuate the establishment of a network communications connection between at least two of the components in accordance with their common behaviors;

maintaining information as to uncommon behavior of the individual control functions of said plurality of components within a data model;

second controlling of network operations using said network control function comprising the steps of;

accessing said data model to extract the maintained information as to uncommon behavior of said plurality of components; and

interpreting the extracted information to tailor the transmitted control orders to account for the uncommon behavior of the individual control function for a given one of the components and effectuate the establishment of the network communications connection between that given component having uncommon behavior and another one of the components in the network.

8. A method for data driven control as recited in claim 7, wherein said control orders comprise orders to perform communications connect, disconnect, reserve and release operations.

9. A method as recited in claim 8, wherein said step of interpreting comprises the step of translating control orders for each common behavior to tailored control orders for uncommon behaviors.

10. A communications system, comprising:

a plurality of network components, each network component having a component control function, each component control function including common control elements shared by each network component in the plurality of network components, and uncommon control elements not shared by each of the plurality of network components;

means for storing information relating to the uncommon control elements of the component control function for each of the plurality of network components in an accessible data model; and

a network controller connected to the plurality of network components, said network controller handling the establishment of a network communications connection between at least two of the plurality of network components using the common control elements of the component control functions, and further including;

means for accessing the means for storing to retrieve the information from the data model relating to the uncommon control elements;

means for interpreting the retrieved information; and

means for handling the establishment of the network communications connection between a certain one of the plurality of network components and another one of the components using the uncommon control elements of the component control functions for the certain network component in accordance with the interpreted information from the data model.

11. The communications system as in claim 10 wherein the establishment of the network connection comprises network communications connect, disconnect, release and reserve operations between the network components, and the information stored in the data model comprises uncommon connect, disconnect, release and reserve operation translation information.

12. The communications system as in claim 11 wherein the establishment of the network connection further comprises network component addressing operations, and the information of the data model comprises network component addressing information.

13. A method for controlling a communications system, the system including a plurality of network components, each network component having a component control function, each component control function including common control elements shared by each network component in the plurality of network components, and uncommon control elements not shared by each of the plurality of network components, the method comprising the steps of:

storing a data model comprising information relating to the uncommon control elements of the component control functions for each of the plurality of network components;

handling the establishment of a network communications connection between at least two of the network components in the communications system using the common control elements of the component control functions for the plurality of network components;

accessing the data model to retrieve the information from the data model relating to the uncommon control elements;

interpreting the retrieved information; and

handling the establishment of the network communications connection between a certain one of the network components in the communications system and another one of the components using the uncommon control elements of the component control functions for the network component in accordance with the interpreted information from the data model.

14. The method as in claim 13 further including the step of updating the stored data model with information accounting for the uncommon control elements of the component control functions for a reconfiguration of the communications system caused by adding to, deleting from or substituting for certain ones of the network components in the communications system.

15. The method as in claim 13 wherein the establishment of the network connection comprises network communications connect, disconnect, release and reserve operations between the network components, and the information stored in the data model comprises uncommon connect, disconnect, release and reserve operation translation information.

16. The method as in claim 15 wherein the establishment of the network connection further comprises network component addressing operations, and the information of the data model comprises network component addressing information.
