10 Gbit/s Connections

Abstract – This work compares commercial fast data transport approaches through 10 Gbit/s Wide Area Network (WAN). Common solutions, such as File Transport Protocol (FTP) based on TCP/IP stack, are being increasingly replaced by modern protocols based on more efficient stacks. To assess the capabilities of current applications for fast data transport, the following commercial solutions were investigated: Velocity – a data transport application of BitSpeed LLC; TIXstream – a data transport application of Tixel GmbH; FileCatalyst Direct – a data transport application of Unlimi-Tech Software Inc; Catapult Server – a data transport application of XDT PTY LTD; ExpeDat – a commercial data transport solution of Data Expedition, Inc. The goal of this work is to test solutions under equal network conditions and thus compare transmission performance of recent proprietary alternatives for FTP/TCP within 10 Gigabit/s networks where there are high latencies and packet loss in WANs. This research focuses on a comparison of approaches using intuitive parameters such as data rate and duration of transmission. The comparison has revealed that of all investigated solutions TIXstream achieves maximum link utilization in presence of lightweight impairments. The most stable results were achieved using FC Direct. ExpeDat shows the most accurate output. Keywords-high-speed data transport; transport protocol
