A certain number of IGEL thin clients or UDC2 converted devices in your company regularly need to be updated. If every device accesses the main update server individually, maybe even over a great geographical distance, the update could take quite a long time and might overload the entire connection.
You want to find a more efficient way of upgrading the devices within a network.
Set up one of your clients as a so called buddy update server. In future, only this client will access the main server to download the updates. All other clients access the local buddy update server from within the network and will no longer offload the network outside.
