Abstract
Systems and methods for transporting data from a source network to a destination network by way of a transport network. Data transmission units (DTUs) from the source network are received at a server logically located between the source and the transport networks. These first DTUs are subdivided into second DTUs and are transmitted to the destination network by way of the transport network. Also transmitted are encoded or extra second DTUs that allow the original first DTUs to be recreated even if some of the second DTUs are lost. These encoded second DTUs may be merely copies of the second DTUs transmitted, parity second DTUs, or second DTUs which have been encoded using erasure correcting coding. At the destination network, the second DTUs are received and are used to recreate the original first DTUs. In the event an insufficient number of second DTUs are received, such that recreating the original first DTU cannot be accomplished, a re-transmission of the second DTUs is requested.
