DART: Enhancing Data Acceleration with Compression for Satellite Links
Thava Iyer, Roksana Boreli, Golam Sarwar, Christoph Dwertmann · 2009
We present data acceleration and reduction technology (DART), a new rate based congestion control and scheduling mechanism with integrated data compression. DART has been implemented in the 7-ip satellite gateway products and is based on SCPS-TP framework. We evaluate the performance of this scheme on two live commercially available satellite systems, IPSTAR and Inmarsat BGAN and compare it to the performance of a number of TCP flavors previously proposed for use on satellite links. We show that on congested satellite links the proposed scheme outperforms the established techniques. We additionally highlight the benefits of data compression when fully integrated within the transport protocol. Finally, we demonstrate fairness of the proposed scheme to other flows.
