• When in doubt, set the DME to preposition.
• Double preposition (to a location) if availability is key.
• Create a naming scheme for your DME streams and video files (Rev enforces
uniqueness of video file names).
• Plan for the appropriate use of your DMEs. Are they simply reflectors? VOD
storage? Stream manipulation and transmuxing? Configuration depends on your
topology and use.
• Most importantly, evaluate your network topology to best utilize the mesh. Vbrick
Customer Service and Professional Services are a good resource for questions and
solutions.
As noted, see the “Preposition DME Content” topic in Rev Online help for details on how to
preposition content in Rev.

To review or troubleshoot the status of your DME within the Mesh, do the following:
1. First, evaluate if the DME is connected to Rev appropriately.
• Navigate to
System Configuration
>
Rev Interface
and make sure the Rev Interface
has been enabled and is running. See: Rev Interface for details if you need
instructions.
• As a short cut, in the bottom of each page to the far right should be two True or
False indicators, one on top of the other. The top indicator is True if the Rev
Interface is Enabled, and the bottom indicator is True if the Rev Interface Service is
running. Both should be True for correct communication to Rev. If either is false,
reset the Rev Interface by going to the
System Configuration
>
Rev Interface
page
verify your settings and uncheck the
Rev Enabled
checkbox, click
Apply
, re-enable it,
and click
Apply
again.
2. Next, inspect the DME settings and connections to peer DMEs within the Mesh.
• Navigate to the
System Configuration
>
Streaming
page and verify the
Cache System
Resources
(Memory/Disk) setting. This is an overall setting that controls the
amount of caching resources the system will use. Please see the Caching topic for
more details.
• Navigate to
System Configuration
>
Caching
. On this page, you can see how the
DME is configured, HLS Remote Hosts, and all the peer DMEs within the Mesh.
Inspect each peer DME to identify connectivity (via the Reachable column) and
when the last connection was made.
• The HTTP Port and ICP Port should be listed at the top of the page. Best practice is
to use using default port numbers (80 & 31030) for proper mesh usage.
• Within the HLS Remote Hosts section you may see 1 or more hostnames – these are
set by Rev if your account is enabled and using the Video Conference Recording and
Streaming functionality. Otherwise, these will be blank. Do not edit these fields.
• Review how this DME is configured, it will be identified as setup/or not for VOD
playback and prepositioning. If the setting is (or should be) different, visit Rev to
centrally reset it.
• Within the Alternative Sources section you should see the list of your peer DMEs (to
this current DME). This DME should be able to reach at least one prepositioned
DME, OR this DME should be prepositioned. If you cannot see all of the peers,
please use the Display dropdown list at the top of the page to increase the display
size.
