Abstract

Exemplary embodiments for programming a network device using user-defined scripts are disclosed. The systems and methods provide for a servicing node to receive a request for a network session between a client device and a server, receive a user defined class and a user defined object configuration from a node controller, and use the information to instruct an object virtual machine to generate at least one user defined object. The servicing node can then apply the at least one user defined object to a data packet of the network session, where the user defined object allows a user to configure the network device with user-defined instruction scripts.

Claims

1. A system for programming a network device with user-defined instruction scripts, the system comprising:

a servicing node, comprising;

at least one user defined object; and

an object virtual machine that executes instructions enabled by the at least one user defined object while the servicing node processes a network session between a client device and a server; and

at least one node controller that sends a user defined class and a user defined object configuration to the servicing node, the user defined class and user defined object configuration used by the servicing node to instruct an object virtual machine to generate the at least one user defined object.

2. The system of claim 1, wherein the servicing node further comprises a network application.

3. The system of claim 2, wherein the servicing node applies the user defined object in conjunction with the network application to process the network session.

4. The system of claim 1, wherein the user defined class includes a template for one or more instruction to create the user defined object.

5. The system of claim 1, wherein the servicing node applies the user defined object after receiving the user defined object configuration and user defined class, prior to the processing the network session.

6. The system of claim 1, wherein the servicing node applies the user defined object after receiving the user defined object configuration and user defined class, while the network session is in progress.

7. The system of claim 1, wherein each of the at least one user defined objects is configured with a different IP address.

8. The system of claim 1, wherein the user defined class requires a license to create the at least one user defined object.

9. The system of claim 1, wherein the object virtual machine determines if a user defined object is applicable to a data packet of the network session.

10. The system of claim 9, wherein the object virtual machine applies a security policy to the data packet of the network session.

11. The system of claim 9, wherein the object virtual machine matches the data packet of the network application with a list of permissible network applications.

12. The system of claim 1, wherein the object virtual machine provides object variables of the at least one user defined object to the at least one node controller.

13. The system of claim 12, wherein the object variables comprise accounting data and statistics data.

14. A method to configure a network device with user-defined instruction scripts, the method comprising:

receiving a request for a network session between a client device and a server;

receiving a user defined class and a user defined object configuration at a servicing node, the user defined class and user defined object configuration used by the servicing node to instruct an object virtual machine to generate at least one user defined object; and

applying the at least one user defined object to a data packet of the network session, wherein the user defined object allows a user to configure the network device with user-defined instruction scripts.

15. The method of claim 14, wherein the user defined class requires a license to create the at least one user defined object.

16. The method of claim 14, wherein the object virtual machine determines if a user defined object is applicable to a data packet of the network session.

17. The method of claim 14, wherein the object virtual machine applies a security policy to the data packet of the network session.

18. The method of claim 14, wherein the object virtual machine provides object variables of the at least one user defined object to the at least one node controller.

19. The method of claim 14, wherein the object variables comprise accounting data and statistics data.

20. A non-transitory computer-readable storage medium comprising instructions, which when executed by one or more processors of a network controller, perform a method for configuring a network device with user-defined instruction scripts, the method comprising:

receiving a request for a network session between a client device and a server;

receiving a user defined class and a user defined object configuration at a servicing node, the user defined class and user defined object configuration used by the servicing node to instruct an object virtual machine to generate at least one user defined object;

applying the at least one user defined object to a data packet of the network session, wherein the user defined object allows a user to configure the network device with user-defined instruction scripts.
