With the continuous deepening of enterprise management and market competition, the pressure of production and operation of enterprises is increasing, and it is urgent to improve the management level of enterprises. This paper mainly studies the decision optimization design of enterprise standardization management planning based on mobile network system. In this paper, the idea of clustering is used to integrate the customers into a customer clustering mode, which will greatly reduce the number of customers studied in the model and simplify the optimization process of the model. Through online and offline processes, these can achieve dynamic and rapid processing of data flow and can well meet the needs of users for data flow analysis. In the construction of enterprise standardization strategic performance evaluation index system, it is necessary to decompose, combine, and converge the index system. According to the construction principles and methods discussed above, the influencing factors of standardized strategic performance evaluation indicators of construction enterprises are preliminarily stratified by using the expert survey method and cluster analysis method, so as to construct the initial evaluation system. For the mobile network system testing, we use the black box test and white box test. The test content mainly includes two modules: area calculation and label calculation. Experimental data show that when the time threshold Ts is set to 1 hour, the prediction accuracy of TBM increases from 46.9% to 47.7%. The results show that the mobile network system realizes the whole life cycle management of enterprise standards and improves the management level of enterprise standardization work.

TCP protocol has an awful performance in the wireless network because of the instability, high BER and long RTT of the wireless link. How to make wireless transmission more reliable and efficient has become a hot topic among relative researches. TCP/NC is a recently proposed protocol based on network coding and capable of achieving much higher throughput than TCP over lossy wireless Links. In this paper, network coding and TCP/NC are outlined firstly. And then simulation realization of TCP/NC protocol in OMNET++ is described. The performance evaluation of TCP/NC is conducted in OMNET++. The results show that TCP/NC offers significant better performance than TCP without affecting the fairness of data flow.

medical application running outside the workstation environment has to deal with several limitations, such as reduced available memory and low network bandwidth. Adaptations and novel approaches are required to make applications overcome such problems. This paper presents an approach that uses a combination of client- and server-side procedures to dynamically optimize the data flow for fast image transfer and visualization on mobile and stationary devices. The main goal of our approach is to minimize the amount of data transferred to and used in the host device without sacrificing the user experience. Our approach was implemented and validated using a real use case, the application Animati Viewer, which is a web visualizer for diagnostic images. The evaluation was measured using metrics such as the accumulated amount of network transferred data and the amount of memory used in the host device. The results show that our approach is feasible and, in one of our tests, it transferred only 7.73% of the amount of data downloaded by the OsiriX mobile.

With the booming of Cloud Compute, OpenStack has been more widely used in Data Center, but in tradition deployment of OpenStack, the traffic must traverse network node to get routing decision. So the network node would be a bottle-neck due to the increasing amount of data flow. In order to solve this problem, this paper propose an extensible design, we create a internal virtual router in each compute node, the internal virtual router just can process the East-West traffic in lay2. With the help of distributed router, the East-West traffic can be delivered directly from the source hypervisor to the destination hypervisor, no longer need to traverse the router in network node to get routing decision, Therefore, North-South and East-West traffic don't impact each other anymore. North-South traffic enjoys all the bandwidth of router in network node exclusively, hence reduce the load of the network node. Experiment results show that OpenStack with distributed router has a much better performance evaluation than original OpenStack. This will dramatically increase the total bandwidth, and also bring other advantages.
