High-speed Transmission and Interoperability Technology: Transport Protocols for Fast Long-Distance Networks: Comparison of Their Performances in JGNⅡ

摘要

The majority of network applications adopt the Transmission Control Protocol (TCP) as the transport layer protocol on IP networks. This is because the TCP has important two functions; one is the error control function providing a reliable, error free data transmission and another is the congestion control mechanism realizing a modest sharing of network resources. However, the current TCP is not always suitable for applications which require highly reliable and high speed transfer of a huge amount of data over long haul networks, such as in the Grid Computing environment. Therefore, various new transport protocols have been proposed with the aim of the efficient use of abundant resources in fast long-distance networks. In this paper, we discuss the results of throughput characteristics of some practical high-speed transport protocols on JGN (Japan Gigabit Network)Ⅱ.
