Abstract

Systems and methods are provided herein. An exemplary servicing node may include: an interface to a data network, the interface coupled to an object machine; and the object machine, the object machine: receiving a data packet from the data network using the network interface, the data packet comprising at least one of a destination address, a destination port number, and an application protocol; determining a condition associated with the at least one of the destination address, the destination port number, and the application protocol; identifying a program name using the condition; executing a program using a name table, the name table linking each of a plurality of program names to a respective program, the executing comprising getting an instruction of the program, the instruction including object information.

Claims

1. A servicing node comprising:

receiving a data packet from the data network using the network interface, the data packet comprising at least one of a destination address, a destination port number, and an application protocol;

determining a condition associated with the at least one of the destination address, the destination port number, and the application protocol;

identifying a program name using the condition; and

executing a program using a name table, the name table linking each of a plurality of program names to a respective program, the executing comprising getting an instruction of the program, the instruction including object information.

2. The servicing node of claim 1 wherein the object machine further:

obtains a class name using the object information;

creates a name entry in the name table;

links the class name to a respective class; and

stores the class name and respective class in the name entry.

3. The servicing node of claim 1 wherein the object machine further:

obtains another program name using the object information;

creates a name entry in the name table;

links the another program name to a respective another program; and

stores the another program name and respective another program in the name entry.

4. The servicing node of claim 1 wherein the object machine further:

obtains a class name and at least one attribute using the object information;

finds an object entry associated with the class name and at least one attribute using an object table, the object entry including values associated with each of the at least one attribute, the values associated with at least one operating parameter of the network node; and

provides the values using the object entry.

5. The servicing node of claim 4 wherein the operating parameter is at least one of a memory utilization, processor utilization, bandwidth utilization at an interface, session utilization, number of new flows per second, and number of malformed requests.

6. The servicing node of claim 1 wherein the object machine further:

obtains a class name and at least one attribute using the object information;

finds at least two object entries associated with the class name and at least one attribute using an object table, the object entries each including values associated with each of the at least one attribute, the values associated with at least one operating parameter of the network node;

selects one of a first of the at least two object entries and an object entry of the at least two object entries randomly; and

provides the values using the selected object entry.

7. The servicing node of claim 6 wherein the operating parameter is at least one of a memory utilization, processor utilization, bandwidth utilization at an interface, session utilization, number of new flows per second, and number of malformed requests.

8. The servicing node of claim 1 wherein the object machine further:

obtains a class name, at least one attribute, and at least one value associated with each at least one attribute using the object information;

finds an object entry associated with the class name and at least one attribute using an object table; and

modifies the object entry to include the at least one value associated with each at least one attribute.

9. The servicing node of claim 1 wherein the object machine further:

obtains a class name, at least one attribute, and at least one value associated with each at least one attribute using the object information;

finds at least two object entries associated with the class name and at least one attribute using an object table, the object entries each including values associated with each of the at least one attribute;

selects one of a first of the at least two object entries and an object entry of the at least two object entries randomly; and

modifies the selected object entry to include the at least one value associated with each at least one attribute.

10. The servicing node of claim 1 wherein the object machine further:

obtains another program name and at least one program parameter value using the object information;

finds an association with another program corresponding to the another program name using the name table; and

executes another program using the association with the another program and at least one program parameter value.

11. A method performed by a servicing node comprising:

receiving a data packet from a data network using a network interface, the data packet comprising at least one of a destination address, a destination port number, and an application protocol;

determining a condition associated with the at least one of the destination address, the destination port number, and the application protocol;

identifying a program name using the condition; and

executing a program using a name table, the name table linking each of a plurality of program names to a respective program, the executing comprising getting an instruction of the program, the instruction including object information.

12. The method of claim 11 further comprising:

obtaining a class name using the object information;

creating a name entry in the name table;

linking the class name to a respective class; and

storing the class name and respective class in the name entry.

13. The method of claim 11 further comprising:

obtaining another program name using the object information;

creating a name entry in the name table;

linking the another program name to a respective another program; and

storing the another program name and respective another program in the name entry.

14. The method of claim 11 further comprising:

obtaining a class name and at least one attribute using the object information;

finding an object entry associated with the class name and at least one attribute using an object table, the object entry including values associated with each of the at least one attribute, the values associated with at least one operating parameter of the network node; and

providing the values using the object entry.

15. The method of claim 14 wherein the operating parameter is at least one of a memory utilization, processor utilization, bandwidth utilization at an interface, session utilization, number of new flows per second, and number of malformed requests.

16. The method of claim 11 further comprising:

obtaining a class name and at least one attribute using the object information;

finding at least two object entries associated with the class name and at least one attribute using an object table, the object entries each including values associated with each of the at least one attribute, the values associated with at least one operating parameter of the network node;
