Abstract
A redundant remultiplexer includes two media control modules, wherein, if the primary module operates in an input mode, the backup module performs the same processing of packets as the primary module but only transmits processed packets to a switch if the primary module fails, and wherein, if the primary module is operating in an output mode, the backup module performs the same processing as the primary output module on the same sequence of packets received from the switch, but the backup module only outputs the processed packets if the primary module fails.
