Rapid increase of network bandwidth and emergence of new distributed applications for big-data, high-speed data transfer protocol are required which is available for LFN (Long-Fat Network) with 10 Gbps or wider bandwidth. A variety of TCP-based protocols have been proposed which show high performance on large latency network conditions. However, TCP protocols are essentially unable to archive high through-put on large latency networks with packet-losses. To overcome this issue, we designed a new data transfer protocol on TCP/IP transport layer: the High-performance and Flexible Protocol (HpFP). We originally designed a new protocol, the HpFP, built on top of UDP. To examine network performance of the HpFP, we implemented an easy-use application, named as “hperf”, which measures end-to-end through-put via HpFP. This application also give us real-time status of packet-loss and latency (RTT). We examine performance of the network monitoring (packet-loss and latency) via HpFP in comparison with “ping” and “iperf”. Examinations via hperf on an international network (10G) are also reported. |
