| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A communications satellite (INTELSAT) data receiving system with a 7.6m-diameter parabolic antenna was installed at Syowa Station in February 2004. After the equipment, data transfer have been carried out using from the Syowa station in Antarctica to NIPR (National Institute of Polar Research) in Tokyo using the satellite communication network. The current bandwidth of the INTERSAT between Syowa and NIPR is 3 Mbps. The latency between Syowa and NIPR is non-negligible, and general file transfer applications, such as FTP, rsync, and rcp, don’t show good throughputs. It is due to restriction of TCP function on networks with large latency. The SteelHead provided by Riverbed is one of the WAN accelerators for such long-distance data transfer. It intercepts TCP on both sides of the network, and accelerates TCP connection replacing with its own data transfer technologies. Another important role of the SteelHead is to control QoS of multiple data tarnsfers. Several projects at Syowa Station in many research fields are being conducted, and data transfers are independently conducted in principle. There needs a traffic control of data transfers over the satellite communication network. Network managers at NIPR give priorities to each data transfer project, and the SteelHead allocates bandwidths to each network connection. However, this QoS controller simply sets highest and lowest bandwidths. Ocasionally total throughput could be lower than 3 Mbps depending on setting of the QoS table. Herein we propose a new data transfer protocol to work on the transport layer; the HpFP (High-performance and Flexible Protocol). This protocol is a connection-oriented protocol to works on the top of UDP. It provides us with a stream-type of reliable data transfer. One of the ingenious attemps in the HpFP is to set an internal target throughput for pace control of sending packets. This parameter setting is time-dependent; the target throughput is calculated based on network conditions monitored by the HpFP. The HpFP is able to detect unused bandwidth at every moment, then dynamically allocates the HpFP data connection. We discuss how effectively the HpFP covers the unused bandwidth on the condition of SteelHead control on the INTERSAT networks based on laboratory experiments. | |
