Abstract
An entertainment system that has improved failure recovery characteristics and reduces the connection components is disclosed. In one aspect, an inflight entertainment system comprises a plurality of physically interconnected head end line replaceable units and a plurality of serially-connected networking line replaceable units physically interconnected in a serial configuration, wherein two of the serially-connected networking line replaceable units at the edge of the serial configuration are physically interconnected with two of the head end line replaceable units, respectively, wherein a loop-free head end data path is maintained between active head end line replaceable units by regulating link participation in the head end data path, and wherein one or more loop-free serially-connected networking data paths are maintained between at least one of the two head end line replaceable units and active serially-connected networking line replaceable units by regulating link participation in the serially-connected networking data paths.
