| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we evaluate the performance of a remote IP storage replication via long-fat network using iSCSI protocol with iSCSI-APT (Automatic Parallelism Tuning), which automatically adjusts the number of TCP connections according to the network status. A new network service, Layer-1 Bandwidth on Demand (L1OD) on SINET3 has just been started its introduction by National Institute of Informatics (NII). L1OD service allows dynamic bandwidth allocation at phsical layer (Layer-1) without disruption. We have been evaluating the performance of iSCSI-APT on SINET3 with L1OD service, but our current iSCSI-APT implementation assumes no chnage in bandwidth allocation during data trasfer. In this report, we analyze the performance of iSCSI-APT with and without a parallelism reoptimization mechanism, which is introduced in this report. Through simulations, we show that the parallelism reoptimization mechanism significantly improves the effectiveness of iSCSI-APT. |
