An adaptive burst assembly scheme for OBS-GRID networks

This paper addresses the problem of burst assembly in OBS-GRID networks and particularly the TCP throughput maximization problem for large file sizes. For that purpose, a novel adaptive size-based approach is proposed, following some probabilistic methods and considering the effect of the burstification process in the overall transport system. The scheme has been evaluated in a high capacity GRID network. It was found that the proposed scheme results in shorter file transfer times, a significant higher TCP throughout, thus yielding a positive impact at the grid mechanics. The performance of the scheme is compared to that of a timer-based algorithm.
