Abstract

A system provides representations of connections or other relationships among entities that make up a communications network. The representations may each have a color or shading to represent different conditions of the relationship. The representations may be graphical and may also include textual information as well as graphical hot-spots selectable by a user to provide even more detailed information regarding the relationship. The condition of each relationship may be determined based upon a combination of the conditions of the interface elements which are coupled together to form the communications relationship.

Claims

1. A method for resolving a condition of a connection within a communications network to a user, comprising the steps of:

(a) determining a condition of a first interface element of the network;

(b) determining a condition of a second interface element of the network, the first and second interface elements sharing the connection within the network;

(c) combining the conditions of the first and second interface elements to determine the condition of the connection from a predetermined plurality of connection conditions the predetermined plurality of connection conditions including a disabled/bad condition indicative that the connection would not be operable even if a disabled one of the first and second interface elements were to be enabled; and

(d) displaying a representation of the condition of the connection to the user.

2. The method of claim 1, wherein:

the first interface element is a first port of a first device;

the second interface element is a second port of a second device.

3. The method of claim 1, further comprising the step of storing a predetermined plurality of interface element conditions, and wherein step (a) includes classifying the first interface element condition as one of the predetermined plurality of interface element conditions.

4. The method of claim 3, wherein the step of storing the predetermined plurality of interface element conditions includes storing the following predetermined conditions:

a good condition indicative that the interface element has an operational status;

a bad condition indicative that the interface element has a faulty status;

an unknown condition indicative that the interface element has an unknown status;

a disabled condition indicative that the interface element has a disabled status; and

an unreachable condition indicative that the interface element has a not communicating status.

5. The method of claim 1, further comprising:

maintaining a logical representation of the network that includes a model representative of the condition of the connection.

6. The method of claim 1, wherein step (c) includes determining the condition of the connection from the following predetermined conditions:

a good condition indicative that the connection has an operational status;

a bad condition indicative that the connection has a faulty status;

an unknown condition indicative that the connection has an unknown status;

a disabled condition indicative that the connection has a disabled status; and

an initial condition indicative that the connection has a recently established status.

7. The method of claim 1, wherein step (c) includes logically combining the conditions of the first and second interface elements to determine the condition of the connection.

8. The method of claim 1, wherein step (d) includes displaying the representation as a graphical image having a selected color based upon the condition of the connection.

9. The method of claim 1 wherein step (d) includes displaying the representation in a plurality of different displays that represent different information about the network.

10. The method of claim 1, further comprising the steps of:

maintaining a logical representation of the network that includes a first model representative of the first interface element and a second model representative of the second interface element;

associating the relationship condition with each of the first and second models.

11. The method of claim 1, further comprising the step of monitoring the network to determine when the relationship is established, and wherein step (a) is performed when the relationship is established.

12. The method of claim 1, further comprising the step of monitoring the network to determine when the condition of the first interface element changes, and wherein step (a) is performed when the condition of the first interface element changes.

13. The method of claim 1, wherein the step (c) of combining includes:

determining a condition of a first data path between the first interface element and the second interface element;

determining a condition of a second data path that is parallel with the first data path, the first data path and second data path providing a parallel data path;

logically combining the condition of the first data path with the condition of the second data path to create a condition representative of the parallel data path;

and wherein the step of displaying includes displaying the condition representative of the parallel data path.

15. The method of claim 1, wherein step (a) includes determining the condition of the first interface element from a predetermined plurality of interface element conditions that is different from the predetermined plurality of connection conditions.

14. An apparatus for resolving a condition of a connection within a communications network to a user, comprising:

first means for determining a condition of a first interface element of the network;

second means for determining a condition of a second interface element of the network, the first and second interface elements sharing the connection in the network;

third means for combining the conditions of the first and second interface elements to determine the condition of the connection from a predetermined plurality of connection conditions the predetermined plurality of connection conditions including a disabled/bad condition indicative that the connection would not be operable even if a disabled one of the first and second interface elements were to be enabled; and

fourth means for displaying a representation of the condition of the connection to the user.

16. The apparatus of claim 14, wherein:

the first interface element is a first port of a first device;

the second interface element is a second port of a second device.

17. The apparatus of claim 14, further comprising means for storing a predetermined plurality of interface element conditions, and wherein the first means includes means for classifying the first interface element condition as one of the predetermined plurality of interface element conditions.

18. The apparatus of claim 17, wherein the predetermined plurality of interface element conditions includes:

a good condition indicative that the interface element has an operational status;

a bad condition indicative that the interface element has a faulty status;

an unknown condition indicative that the interface element has an unknown status;

an unreachable condition indicative that the interface element has a not communicating status.

19. The apparatus of claim 14, further comprising means for maintaining a logical representation of the network that includes a model representative of the condition of the connection.

20. The apparatus of claim 14, wherein the predetermined plurality of connection conditions includes:

a good condition indicative that the connection has an operational status;

a bad condition indicative that the connection has a faulty status;

an unknown condition indicative that the connection has an unknown status;

a disabled condition indicative that the connection has a disabled status; and
