Video Delivery

AppNeta Performance Manager (APM) has monitoring capability designed specifically for ensuring good video conference quality. You can perform discrete tests that account for network path, number of calls, direction, codec, etc. These tests, which can be run on-demand or scheduled, enable you to measure how network security and traffic-shaping impacts video calls, and verify that qos is having the desired effect. You can execute a video test only a path that has a source monitoring point with an video delivery license.

Video tests can create significant load: Unlike continuous monitoring and diagnostic tests, video tests can create significant load, especially when tests include several sessions, or when multiple tests are run concurrently.

Create a video test
Video tests can simulate one-to-one, one-to-many, and many-to-many conferencing scenarios. To support these use-cases, tests are constructed in units called sessions. Each session is based on one path, a number of calls, call direction, codec, bit rate, and qos.
Save a video test
Save all of the video test sessions and settings. You can find your saved test on the tests tab of the manage video test page. From the action menu you can schedule, edit, delete, or run the test.
Save as template
Video templates enable you to save a test configuration so that you can re-run it later against the same or different paths. Saved templates are listed on the templates tab of the video delivery main page.
  • Create a new template: Saves all of your sessions and settings, except for path name.
  • Add to existing template: Adds only the test sessions to the template. The template’s existing test name, comments, and duration are retained.
Schedule a video test
Configure APM to repeat a test periodically. You can find your test schedules on the schedules tab of the manage video tests page. Click anywhere on the row of a test schedule to see its details. You can’t edit a schedule; instead, copy it, make your changes, and then delete the original.
View test results
From the manage video test page, click the row of any test; you don’t need to wait until the test is finished, the results page updates every 30 seconds.

Combine Templates! Use bulk action on the templates tab to select multiple templates. Then select ‘create test’ from one of their action menus. The template performing the action absorbs the sessions from the other template.

Testing capability

The non-G.726 limits shows for each bit rate the number of calls that would be equal to 100% monitoring point load. You can have multiple sessions with different bit rates, so long as the monitoring point load doesn’t exceed 100%. For example, an m20 can handle 6 one-way calls at 1024 kbps and 7 two-way calls at 128 kbps at the same time. You don’t need to calculate monitoring point load in advance. APM will reject any test configuration that exceeds monitoring point load for either the source or the target, and an error message will indicate which monitoring point would be overloaded and by how much.
