Using Mirage branch reflectors promotes efficient distribution to branch offices and remote sites where multiple users share the WAN link to the data center. You can enable the branch reflector peering service on endpoint devices that are installed with a Mirage client.
The branch reflector downloads base layer images, app layers, driver files, and USMT files from the Mirage server and makes them available for transfer to other Mirage clients in the site. Only files that reside on the branch reflector machine's disk are transferred and files are not requested from the Mirage server at all.
In this way, files are downloaded to the branch reflector only once, and common files across base layers become readily available to other clients without duplicate downloads.
