ABSTRACT:
An apparatus and methods are provided for the communication of a data stream and management of faults in a multipath data network having a protected ring-in-ring network architecture. The data stream is communicated over redundant paths between various nodes located throughout the network. Each node is capable of dropping and inserting data from the data stream before passing it on to the next node. A single transmitter in communication with an intelligent splitter at each node is utilized to simultaneously transmit the data stream over the redundant paths. In the event of a fault over one of the paths in the network, the intelligent splitter manages the operation of the single transmitter so that the data stream is communicated over an alternate path to circumvent the fault.
