Abstract: With the development of the Botnet, new botnets use the peer-to-peer (P2P) protocol (such as for eMule download) appear, which have brought great challenges in detecting and preventing of botnet in the data center.27100Point to point protocol uses more decentralized control method, so information between each node can be shared, and each node has the function of connecting and recovering, which leads to that the class of Botnet is hard to be closed. In the protection of Botnet the data center also found that there are more and more botnet uses the high strength encryption technology after implanting into hosting, which makes the application layer information of the whole communication process be invisible to zombie network protection system for data centers , resulting in many missing events on the recognition and Influences the safety management effect. The specific point of view, point to point protocol and communication method based on encryption led to the that a data center in the botnet protection system is difficult to deal with effectively

Abstract: There is the extremely high radiation in the detector of ATLAS for LHC (Large Hadron Collider). The upgrading ATLAS Liquid Argon Calorimeter readout optical data link includes on-detector (front-end) and off-detector (back-end). There are the data stream burst continuous multi-bits errors and bit slip when the high-speed data are collected and transferred under the extremely high levels of radiation environment on the front-end. The data is restored on the back-end by FPGA. The design and implementation of error simulator based a Xilinx Kintex 7 for front-end is proposed in this paper to support the design and simulation test of the decoder and encoder of LOCic. Experimental and data analysis show it is valid.

Abstract: Overlapping community detection is a key approach to study the structure of network. Link community approach redefines the community into the collection of edges, which shows great advantages. But with the increasing number of edges in the network, the efficiency of link community algorithm is severely degraded, so that this algorithm lost scalability. In order to detect the large overlapping community efficiently, we proposed a method DLCH (detecting link communities based on Hadoop), mapping link communities method to MapReduce framework, an efficient detecting communities platform for large complex communities. It can successfully store and process massive data by HDFS, and divide the work to map and reduce tasks, which can detect the complex communities efficiently. According to the experiments on standard test data, this method is scalable and effective.

Abstract: Microsoft office Excel is an important part of the Microsoft Office suite of software that can be processed, statistical analysis of various data, with its quick style and rich functionality has been generally welcomed, but with the database networking and sharing trends deepening, Excel application bottlenecks in stand-alone mode began to appear, and the network is the computer information technology in today's inevitable end, I imagine combining ADO technology developed by Delphi Excel data server in order to break this limitation, changes in non-network applications Excel mode.Excel Data Server is a set of services and client program, the server deployed on the server, the client is retrieved by the query language SQL, Excel data file can perform various operations and customer interface directly to form a Web-based application systems, customer service not only to support the application at both ends of the LAN, you can also support the application on the Internet. In this paper, Delphi7.0 support, using ADO and RemObjects SDK tools to develop an Excel data server. RemObjects referred to RO. RO version a lot, but it is recommended to use RemObjects Data Abstract 6.0.43.801, Delphi's experience in the development of it appear to be more stable, server-side and client-side data connections and programming efficiency, data manipulation more convenient.

Abstract: In today's vehicle networking system architecture is mainly composed of four parts: sensor networks, wireless communication networks, cloud computing platforms and vehicle terminal. Wireless sensor network is responsible for the front of the real-time collection of traffic information, a wireless communication network to send information to the backend of the cloud computing platform, cloud computing platform to handle a large number of vehicles to collect real-time information from the front, and finally sends the information to the end user. In this thesis, this car networking research background, analyze vehicle networking system architecture consisting of performance indicators for each part of the system recognize cloud platform for large data processing efficiency as well as room for improvement. Then put forward the traditional computing platform I / O disk database with in-memory database to replace the cloud to enhance cloud computing platform for large data processing efficiency.

Abstract: As a medium forcommunication and coalition, social network plays an important role in economicactivities. Empirical researches indicate that most of social networks performsignificant small-world characteristics, so this paper assumes the socialnetwork among merchants is a small-world network, and then studies the agencyactivities of merchants by means of simulation based on a game model. We findthat if the average degree of the network increases, the wage of agents willdecrease and social efficiency will increase, but the probability of emergenceof third-part institutions such as courts, which is the basis of modern marketeconomy, will decrease.

Abstract: With advances in data collection and generation technologies, environments that produce data streams is more and more. In recent years, the network application is further universal and the applications of a single data stream transfer toward a multi-node distributed data streams, such as sensor network, network monitoring, web log analysis and the credit card transaction data of multiple sites. These data is not only real-time, continuous and large scale, but also distributed. How to manage and analyze large dynamic datasets is an important subject that researchers are faced with. In view of the situation, it presented the formalization description of homogeneous and heterogeneous distributed data stream in this paper, analyzed advantages and disadvantages of the centralized stream processing architecture and distributed streaming processing architecture, discussed the recent progress in distributed data stream classification algorithm, summed up the problems and challenges faced by the distributed data stream mining, and possible future research directions.
