*This is a demo system of FastBTS deployed on four test servers (two in China and two in America). Due to the small number of test servers, data-driven server selection (DSS) and adaptive multi-homing (AMH) are currently not fully supported. In addition, we are still working on some bugs caused by VPNs. Any suggestions or comments can be mailed to,, and We are sincerely looking forward to your valuable feedback to help us further improve FastBTS.
