1. An inflight entertainment system comprising: a first head end line replaceable unit (HE-LRU); a second HE-LRU; a third HE-LRU; the first, second, and third HE-LRUs each comprising: the first, second, and third HE-LRUs configured to communicate via a head-end data-path comprising: wherein, in response to determining that the head-end data-path forms a closed system, the first HE-LRU, under control of its processor, deactivates communication via the second link, thereby forming a loop-free head-end data-path; and wherein, in response to a failure of the first link, the first HE-LRU, under control of its processor, activates communication via the second link, thereby restoring the loop-free head-end data-path.
