Remote Collaboration And Sharing Of Large Material Analysys Instruments

This paper introduces a remote collaboration and sharing platform of large instruments. Reservation and management system, single-sign-on system and network speed problem are discussed in this paper. At last, this paper briefly introduces the application of the remote collaboration and sharing system on AFM and SEM, and deployment of the video terminal.This paper developed a reservation and management system for the collaboration and sharing platform employing ASP+SQL SERVER 2000, and integrated it into the website of Instruments center of Shanghai Jiaotong University. We also employed storage process to speed up the reservation system. For users from Shanghai R&D Public Service Platform(SGST), we developed a Single-Sign-On(SSO) system collaborating with SGST and Beijing TRS Company, so that they can log in our reservation system by using their account and password in SGST. This paper briefly introduced the principle of SSO and bring up a method that deploying a transit page on a server in SGST to speed up the access. The problem of network speed is also discussed in this paper. We tried three methods to solve this proplem ,include Two-Host, Reserve Proxy and Policy Routing, finally we choose Policy Routing and give some graphs to show the result.At last, this paper also discussed some application of the whole system running on AFM and SEM.
