TCP BASED NETWORK ROUTERS SUPPORTING NETWORK CODING AND TCP BASED DATA STREAMING SYSTEM USING NETWORK CODING

摘要

According to embodiments of the present invention, a data streaming system performing network coding comprises: at least one transmission node to generate source data; an encoding router; and a decoding router. The encoding router drives an encoding application which performs network encoding in an application class to create a TCP session between the at least one transmission node and the encoding router, receives the source data from the transmission node through the TCP session, creates a TCP session between the decoding router and the encoding router, generates network-coded data according to a network coding coefficient matrix and the source data, and transmits the network-coded data and elements of the network coding coefficient matrix to the decoding router through the TCP session. The decoding router drives a decoding application which performs network encoding in an application class to reconstruct the source data by decoding or approximate decoding based on the network-coded data and the elements of the network coding coefficient matrix received from the encoding router through the TCP session.
