System and method for achieving accelerated throughput

Abstract

Systems and methods for transporting data between two endpoints over an encoded channel are disclosed. Data transmission units (data units) from the source network are received at an encoding component logically located between the endpoints. These first data units are subdivided into second data units and are transmitted to the destination network over the transport network. Also transmitted are encoded or extra second data units that allow the original first data units to be recreated even if some of the second data units are lost. These encoded second data units may be merely copies of the second data units transmitted, parity second data units, or second data units which have been encoded using erasure correcting coding. At the receiving endpoint, the second data units are received and are used to recreate the original first data units.
