Development of WAN Accelerator Equipment by Hitachi Offering 15 time Faster Data Transfer Speed over Conventional TCP/IP
There is growing demand for transferring large volumes of graphical data such as CAD (Computer-Aided Design) data between global Wide Area Networks (WANs). However, the currently used TCP/IP protocol does not offer an adequate performance over long-distance global links due to severely impacted throughput by round trip delay and packet loss. Commonly used content-cache technologies won’t be able to remedy this issue due to their waste of bandwidth when delivering large volumes of frequently updated data.
To overcome this issue, Hitachi has developed, what company refers to as WAN Accelerator capable of dramatically speeding up the data transfer over a long distance for large volume of graphical design type of data. The new technology is 15 times faster than conventional TCP/IP, promising to improve the productivity of global banks and manufacturers, such as automobile, steal as well as semiconductor industries. Hitachi WAN Accelerator technology is not catch oriented solution, while making best use of the physical bandwidth of communication channels, reducing the time to access data updates. The new technology is capable of measuring packet loss ratio in real-time and estimating the available bandwidth, resulting in optimized real-time data transfer speed. Hitachi WAN accelerator Family product can be installed at both ends of circuits within existing network, without any changes to network design or client terminal and server applications. The new development is a result of joint research between Hitachi and Honda R&D Co., Ltd and the technology was tested between Japan and United State Sites in February of 2011 where the result was confirmed. The initial model will go on worldwide sale from January 12th, 2012.
