Distributed Network Test Systems And To Achieve

By studying the model, real-time and realization of the networked test system, we bring forward the new way to improve real-time and synchronization of the networked test system through the Internet Control Message Protocol (ICMP) and the resource reservation protocol (RSVP). By analyzing the technology of network, test and network information integration, then designs a hierarchy model with extensible and flexible structure, summarizing about advantage and difficulty of networked test. The dissertation introduce some clock synchronization sources and the implementation of clock synchronization using the technology of hardware and software. The way of clock synchronization using ICMP is described.By exploringly analyzing the feature of networked test system and the performance of the network based on TCP/IP, provide some ways to improve the indication of real-time behavior. The conclusion to be draw is that the RSVP is the preferred solution in these types of applications according the result of the experiment.In order to realize the networked test system with open architecture and promote the standardization and real-time of the architecture,the dissertation brings forth an open architecture of Distributed Networked Test System based on the exploration and research of the Electronic Measurement Distance Practicality Experiment System, which is composed of Test-Center Server and Test Server. The paper also analyses the key techniques of building the networked test system.Basing on the Modem Test Technology and Application Laboratory, this The dissertation introduces the build of the Electronic Measurement Distance Practicality Experiment System, expatiates on several key techniques of building Network Lab System.
