With the constant increase of multimedia internet penetration as well as rapid spread and sharing of various information, people pay more and more attention to the information related to daily power utilization. In order to realize the interaction between power companies and power utilization information of users, the power companies apply and register their public accounts to establish their own...
The Intel Atom C2000 Microserver, codenamed Avoton and Rangeley, is a complete server and embedded processor system on chip (SoC) that provides up to seven times greater performance and six times the energy efficiency versus the prior-generation processor. Leveraging the Atom Silvermont microarchitecture, Intel's 22-nm tri-gate manufacturing process and a robust set of integrated I/O, Intel is expanding...
Long period of petroleum exploration has accumulated mass materials of multi-source and multi-scale correlated with geographical position, including seismic, logging and geological data, etc. However, the present management system of the petroleum company cannot integrate and manage these materials effectively, making it difficult to organize and share the information. With the application of GIS,...
Self-organizing and load balancing are both important research directions today, but there is not much similar research in network measurement server. In this paper we firstly investigate the overhead proportion of network measurement server by analyzing actual data. And then a model of self-organizing and load balancing server cluster is proposed, along with the estimation algorithms of single integrated...
As the most popular application in Internet, the performance of web applications are drawing more attention of users and Internet service providers. In order to monitor and analyze user perceived web performance in real network of China, a group of web performance parameters are used which can reflect high layer protocol performance directly impacting user feeling when visiting webpages. A distributed...
Currently, there are two major technologies: FDT/ DTM and EDDL in the field bus device integration domain. But they are not consistent with each other, and lack of integration between two kinds of techniques. This paper describes that integrates these two technologies into OPC UA cLient/server architecture, and gives mapping of the DTM to the OPC UA address space node and EDD to OPC UA address space...
DNS is an important application as a part of the procedures of most Internet applications, which means quality of DNS directly influences quality of these applications. In order to monitor and analyze user perceived end-to-end quality of DNS applications, two key parameters of DNS quality were chosen. A distributed system NQM was used to monitor various types of practical DNS services by deploying...
Software as a Service (SaaS) has been adopted in a fast pace for applications and services on software clouds. However, the success of SaaS in software cloud cannot obscure the integration challenges faced by developers and enterprise infrastructure IT. Among those challenges, firewall/NAT traversal and security issues often pose a serious bottleneck as enterprises may not be entirely comfortable...
Botnet has become a prevalent platform for malicious attacks, which poses a significant threat to Internet security. Recently, botnets are inclined to utilize HTTP to route their command and control (C&C) communication instead of using the protocol Internet Relay Chat (IRC). And these web-based C&C bots try to blend into normal HTTP traffic, which makes them more difficult to be identified...
Software-as-a-Service (SaaS) is an emerging software application delivery model. It has gained an increasing momentum, and it is being adopted at a very fast pace. However, the integration of SaaS applications with enterprise on-premise applications has become a major factor for the success of its adoption. There is a critical need for methods and communication infrastructures that can enable distributed...
Based on the analysis of FTP process and investigation of user perceptions, a set of FTP service QoS parameters are proposed from the user's perspective. These parameters are defined in terms of delay, throughput and usability. Detailed definition of each parameter is presented and its effect on user perceptions is well described. In order to evaluate the effectiveness of these parameters, an active...
These years, P2P applications have multiplied, evolved and take a big part of Internet traffic workload. Identifying the P2P traffic and understanding their behavior is an important field. Some port, payload and transport layer feature based methods were proposed. P2P traffic identification methods by examining user payload or well-defined port numbers no longer adapt to current P2P applications....
These years, P2P applications are very popular on the Internet and take a big part of the Internet traffic workload. Identifying the P2P traffic and understanding their behavior is an important field. However, previous P2P traffic identification methods by examining user payload or well-defined port numbers no longer adapt to current P2P applications. In this paper, we develop a statistical methodology...
P2P IPTV applications start to be very popular on the Internet. Previous work on measuring and analyzing P2P IPTV traffic mostly focuses on a specific type of P2P applications or the behavior characteristics of P2P IPTV nodes acting as a client. In this paper, we have undertaken an in-depth measurement and modeling study of the most common P2P IPTV applications, specially focusing on the behavior...
Mesh-pull based P2P live media streaming system has gained a lot of interests and successes, and collecting key metrics in time from millions of peers to monitor the system level quality is very important for its successful commercial deployment. But the real-time monitoring still faces great technology obstacles, especially considering the dynamic and large-scale scenario which is very common in...
