The characteristics and service conditions of LAN eXtensions for Instrumentation(LXI) are analyzed. Two problems including multi-user control conflicts and data-sharing are pointed out. Some solution are adopted as follows: binding the event notification to overlapped I/O to increase the bearing capacity of the server, then using VXI-11 protocol to realize the mutually exclusive access control and using User Datagram Protocol(UDP) of Silverlight to transfer network stress to the remote nodes. Through tests in different environments, it indicates that the method proposed in this paper can effectively increase the ability of the network loading, as well as the information synchronization and the security.
