Endpoint selection in a network test system

1. A method for testing a network, comprising:

displaying a graphical user interface including a graphical representation of endpoints available for selection as endpoints of traffic to be generated during a test session and a tabular list describing selected endpoints;

selecting source endpoints for the traffic, selected source endpoints designated on the graphical representation of endpoints and described in the tabular list;

selecting destination endpoints for the traffic, selected destination endpoints designated on the graphical representation of endpoints and described in the tabular list; and

generating traffic from the selected source endpoints for transmission to the selected destination endpoints via the network.

2. The method of claim 1 , wherein selecting source endpoints comprises a user selecting a predefined template identifying a plurality of endpoints.

3. The method of claim 1 , wherein selecting source endpoints comprises one of a user adding an entry to the tabular list and a user editing an existing entry in the tabular list.

4. The method of claim 3 , wherein each entry in the tabular list includes a start port number, a port count, a start device number, and a device count.

5. The method of claim 3 , wherein user entries in the tabular list are automatically reflected in the graphical representation of endpoints.

6. The method of claim 1 , wherein the graphical representation of endpoints comprises a graph, wherein

a first axis of the graph represents ports,

a second axis of the graph represents devices, and

each point on the graph represents a specific device emulated by a specific port.

7. The method of claim 6 , wherein

the graph is a two-dimensional rectangular matrix,

rows of the matrix represent respective ports, and

columns of the matrix represent devices.

8. The method of claim 6 , wherein

the graph is based on a polar coordinate system,

an azimuth axis of the graph represents ports, and

a radial axis of the graph represents devices.

9. The method of claim 6 , wherein

the graph is a two-dimensional representation of a three-dimensional space, and

a third axis of the graph represents groups of ports.

10. The method of claim 6 , wherein selecting source endpoints comprises one of a user designating an area of the graph and a user modifying a previously-designated area of the graph, whereby all points within the designated area are selected as endpoints.

11. The method of claim 10 , wherein designating and modifying are performed using a pointing device.

12. The method of claim 10 , wherein designated or modified areas of the graph are automatically reflected in the tabular listing of selected endpoints.

13. A test manager for a network test system, comprising:

a non-transitory machine readable storage medium storing instructions that, when executed, cause a computing device to perform a method for testing a network, the method comprising:

displaying a graphical user interface including a graphical representation of endpoints available for selection as endpoints of traffic to be generated during a test session and a tabular list describing selected endpoints;

selecting source endpoints for the traffic, selected source endpoints designated on the graphical representation of endpoints and described in the tabular list;

selecting destination endpoints for the traffic, selected destination endpoints designated on the graphical representation of endpoints and described in the tabular list; and

generating traffic forming data to cause a plurality of port units to generate traffic from the selected source endpoints for transmission to the selected destination endpoints via the network.

14. The test manager of claim 13 , wherein selecting source endpoints comprises a user selecting a predefined template identifying a plurality of endpoints.

15. The test manager of claim 13 , wherein selecting source endpoints comprises one of a user adding an entry to the tabular list and a user editing an existing entry in the tabular list.

16. The test manager of claim 15 , wherein each entry in the tabular list includes a start port number, a port count, a start device number, and a device count.

17. The test manager of claim 15 , wherein user entries in the tabular list are automatically reflected in the graphical representation of endpoints.

18. The test manager of claim 13 , wherein the graphical representation of endpoints comprises a graph, wherein

a first axis of the graph represents ports,

a second axis of the graph represents devices, and

each point on the graph represents a specific device emulated by a specific port.

19. The test manager of claim 18 , wherein

the graph is a two-dimensional rectangular matrix,

rows of the matrix represent respective ports, and

columns of the matrix represent devices.

20. The test manager of claim 18 , wherein

the graph is based on a polar coordinate system,

an azimuth axis of the graph represents respective ports, and

a radial axis of the graph represents devices.

21. The test manager of claim 18 , wherein

the graph is a two-dimensional representation of a three-dimensional space, and

a third axis of the graph represents groups of ports.

22. The test manager of claim 18 , wherein selecting source endpoints comprises one of a user designating an area of the graph and a user modifying a previously-designated area of the graph, whereby all points within the designated area are selected as endpoints.

23. The test manager of claim 22 , wherein designating and modifying are performed using a pointing device.

24. The test manager of claim 22 , wherein designated or modified areas of the graph are automatically reflected in the tabular listing of selected endpoints.

25. The test manager of claim 13 , further comprising:

a storage device comprising the non-transitory machine readable storage medium;

a processor and memory coupled to the storage device and configured to execute the stored instructions.
