Cyberinfrastructure and Software Development ResearchInternet Tele-MicroscopyIn partnership with The Ohio State University’s Center for Accelerated Maturation of Materials (CAMM), OSC is enabling a set of world’s most powerful electron microscopes remotely accessible to researchers and industries over the Internet. Remote access of the OSU Electron Microscope (OEM) application or Tele-microscopy poses unique challenges: Tele-microscopy requires high resolution video image transfers (~30Mbps per session) with stringent and real-time control requirements for mouse and keyboard actions to remotely manipulate the OEM application controls. Degradation in image quality transfers can seriously hamper end-user Quality of Experience (QoE), making the application practically unusable. In addition, improper mouse and keyboard controlling due to network bottlenecks could result in physical damages to the electron microscope equipment that could cost in excess of $100,000 to fix. We have conducted several objective (active and passive network measurements) and subjective (mean opinion scores) application performance measurements on Tele-microscopy. Our analysis has revealed - how network variations affect end-user perception when using multimedia applications involving video image transfers and simultaneous remote control over advanced networks.
