UDT as an Alternative Transport Protocol for GridFTP
نویسندگان
چکیده
GridFTP has emerged as a de facto standard for secure, reliable, high-performance data transfer across resources on the Grid. By default, GridFTP uses TCP as its transport-level communication protocol. It is well known that TCP Reno cannot provide satisfactory performance on high-speed, long-delay networks. In this paper, we describe how we enabled GridFTP to use UDT as an alternative transport-level communication protocol. We compare the performance of GridFTP over UDT with GridFTP over TCP on various test beds. We also study the impact of UDT on bulk TCP flows.

A decade ago it was theorized that if enough parallel processing power was thrown at an I/O problem, the bottleneck would shift towards the NIC’s link speed [1]. However, today NUMA architecture changes this paradigm, it also matters on which cores these threads are located and how they are managed [2]. Transport protocols are also critical in high latency networks, TCP’s congestion control alg...
