Devices : The All Devices Module : Preposition DME Content
  
Preposition DME Content
This feature is used in conjunction with the DME mesh caching configuration (See the “Mesh with Rev Caching Configuration” topic in DME Online help).
With this configuration, you can designate which DMEs in your video ecosystem will have content prepositioned (downloaded to the DME immediately after upload) by selecting the Preposition Content checkbox. This option is only available for DMEs that are also selected as a VOD Playback Device.
Rev will use zone logic to route content requests by end users to the closest DME. If the DME closest to the user does not have the requested content, that DME will get the content from a “sister” DME that has the content. The content will then be cached on the new DME and will be available for the next person requesting it. Initially, the only “sister” DMEs that will have the content are the prepositioned DMEs. Subsequently, as the content becomes available on more DMEs based on user content requests, any DME that has cached a copy of the content will be a sister DME from which other DMEs can then retrieve the content.
This means that content is only pushed to a handful of DMEs initially, so fewer downloads will be pushed through the cloud and into the network for Rev cloud customers.
 
Note: You should make sure that all DMEs in your network are able to communicate with at least one DME that has all prepositioned content.
As mentioned, view the “Mesh with Rev Caching Configuration” in DME Online help for details on how to enable mesh caching in DME.
