%X <p>In order to guarantee high reliable service in optical burst switching(OBS)networks and reduce the end-to-end delay of bursts, an online burst encoding mechanism based on irregular repeat accumulate(IRA) codes was proposed. The parity-check matrix of IRA codes was adjusted into a special structure, and then an on line IRA (OL-IRA) code which can encode and decode burst online was constructed. Information data bursts are encoded by OL-IRA codes to recover lost bursts with redundant bursts. Simulations show that OL-IRA codes will guarantee the performance of burst loss recovery, and can also shorten the delay of burst loss recovery.</p>
