In this paper, we describe the integration of dynamic right-sizing — an automatic and scalable buffer management technique for enhancing TCP performance — into GridFTP, a subsystem of the Globus Toolkit for managing bulk data transfers across computational grids. Such grids are often characterized by networks with large bandwidth-delay products. Unfortunately, many of today’s grid applications use only a small fraction of available bandwidth because the default buffer sizes in TCP are tuned for… CONTINUE READING
