US 7,013,467 B1 · System and method for managing computer system resources using command control vectors

Abstract

A system, method and computer program product for processing multiple tasks using a single copy of a data object employs command control vectors (CCVs) for representing tasks. A CCV includes pointers to method objects that store instructions for processing tasks and pointers to data objects that store temporary data generated by execution of the method objects. A command response manager manages a queue of CCVs. A separate CCV is generated for each session thread. Multiple CCVs can point to the same method object so that only a single copy of a method object needs to be provided. In one embodiment, CCVs are used in a telecommunication network emulator, where each CCV points to a command response table method object that includes a variety of responses for a variety of inputs. When a CCV points to a script invocation within a command response table, the CCV includes a field for pointing to the invoked script, a field for pointing to a particular offset within the script and a field for pointing to a data object that stores data associated with execution of the script for the CCV. The temporary data object and the virtual instructions of the script form a virtual data object.

Dependent claims

A method for managing computer system resources, comprising:

generating a first command control vector for a first input message, the first command control vector identifying a method object that contains one or more instructions for processing the first input message, wherein the generating a first command control vector comprises:
identifying the method object in the first command control vector, and
identifying, in the first command control vector, a first current instruction of the method object, wherein the first current instruction is used to process the first input message;
generating a second command control vector associated with a second input message, the second command control vector identifying the same method object identified by the first command control vector, the method object containing one or more instructions for processing the second input message, wherein the generating a second command control vector comprises:
identifying the same method object in the second command control vector;
and
identifying, in the second command control vector, a second current instruction of the method object, wherein the second current instruction is used to process the second input message;
providing a single copy of the method object for the first and second command control vectors;
and
processing the first and second input messages using the single copy of the method object.
