Definitions
The following definitions will be used throughout this document in describing the prior art as well as the present invention and its embodiments:
Hierarchical model—an object oriented model in which parent-child relationships are defined. Reference
FIG. 1
(
0101
) for a typical example of this model.
Coarse-grained model—a semi-object-oriented model in which there is only a very limited amount of object instances. A coarse-grained model typically only defines a limited number of object classes and deals with a very limited number of object instances (tens of objects). Reference
FIG. 1
(
0102
) for a typical example of this model.
Fine-grained model—an object-oriented model in which there is an object instance for each entity in the problem domain. A fine-grained model typically defines an object class for each entity type in the problem domain and deals with lots of object instances (thousands to millions of objects). Reference
FIG. 1
(
0103
) for a typical example of this model.
Facade object—an object that acts as a front (or shell) for dispatching requests to an actual modeled object. A facade object is the key towards the definition of coarse-grained modules.
Fully Distinguished Name—a unique identifier for objects in hierarchical object modules. A FDN is a sequence of Relative Distinguished Names (RDNs). An RDN is a name-value pair (NVP) in which the name is commonly referred to as the Distinguished Name (DN). Each child of the same parent has a unique RDN. In other words, each RDN is unique within its parent's context.
Object View—the definition of the (sub)set of attributes and the (sub)set of operations visible on the object. Different views on the same object have a different set of attributes and/or a different set of operations available on the object.
1. Background of the Invention
The present invention is related in the general area of object oriented programming and the definition of fine-grained models in situations where only coarse-grained models are available. In these situations, the prior art generally teaches a strongly typed interface which requires the client and server to be modified for each change in the IDL interface. This is in part because typical object oriented interfaces do not support multiple views on the same modeled object.
2. Description of the Prior Art
Typical object oriented frameworks such as CORBA allow static interface discovery per object class, but do not permit a dynamic interface per object instance. Thus, the prior art teaches that while a framework of views may be generated, these views are generally static in nature.
Additionally, the prior art provides no mechanism of browsing and/or manipulating a model view. These limitations make it difficult if not impossible to traverse a modeled object and perform inquiry and/or manipulation operations on that object.
OBJECTS OF THE INVENTION
Accordingly, the objects of the present invention are (among others) to circumvent the deficiencies in the prior art and affect the following objectives:
(1) To permit multiple views to be supported in an object oriented framework.
(2) To permit browsing and/or manipulation of modeled object through a variety of coarse-grained and/or fine-grained model views.
(3) Within a network management context, to utilize fine-grained views to enable enhanced network element management functions.
While these objectives should not be understood to limit the teachings of the present invention, in general these objectives are achieved in part or in whole by the disclosed invention that is discussed in the following sections. One skilled in the art will no doubt be able to select aspects of the present invention as disclosed to affect any combination of the objectives described above.
BRIEF SUMMARY OF THE INVENTION
Overview
As illustrated in
FIG. 2
(
0200
), the present invention details a network navigator system and method incorporating a client/server (
0210
,
0220
) architecture in which a network coarse-grained model (or single object) (NameSpaceObject) (
0211
) is used to browse/manipulate a fine-grained object model (
0221
). The disclosed invention permits a client application (
0210
) to discover the detailed interface provided by each object instance in the fine-grained model (
0221
).
A client application wishing to invoke an operation on a server-side object first obta
