High-speed File Transfer BI.DAN-GUN
RPS bit loss reduction technology

High reliability file transfer engine

Achieving High speed file transfer with high reliability even under poor quality line conditions by using RPS (Random Packet Stream) technology developed by Fujitsu Laboratories.

RPS technology

• Re-creating lost packets
  RPS creates control data in addition to payload data by using a specific algorithm.The control data size is approx. 3% of data to be transferred. RPS will attempt to re-create lost packets by using this control data without the need to re-send lost packets.
• Minimizing the size of data in case of re-send
  Due to severe packet loss, sometimes RPS is unable to re-create lost packets.In this case, RPS will request only the data which RPS could not re-create. With this feature, network performance degradation is minimized.
  

Essential tool in areas with prevalent high latency communication infrastructure such as BRICS or typical Internet communication

• In a high latency test connection between Japan and Thailand, BI.DAN-GUN was 3.5 times faster than WAN Optimization Service product provided by competitor. This is because BI.DAN-GUN could minimize re-sending data compared to other products due to RPS function.
• In case of file transfer through Internet-VPN, BI.DAN-GUN transfers files 3 times faster than FTP. (Between Japan and Thailand)
• Transfer from Japan to Asia
