With the rapid development of the Internet, network review information shows explosive growth. How to make an accurate analysis of these web comments has become an important issue in the research of network public opinion. In this work, a traditional dictionary based algorithm is adopted to analyze text sentiment of these comments. A deep learning method is proposed to analyze the network public sentiment...
In the Internet of Things (IoT), we all are ``things''. Graph theory, a branch of discrete mathematics, has been proven to be useful and powerful in understanding complex networks in history. By means of graph theory, we define new concepts and terminology, and explore the definition of IoT, and then show that IoT is the union of a topological network, a data-functional network and a domi-functional...
Mobile Internet traffic keeps a fasting-growth globally. This paper is to shed light on the traffic analysis and policy control in EV-DO systems. Large-scale datasets collected from an urban area are studied for characterizing the application/subscriber usage and downlink-uplink imbalance. Our observations show that HTTP and P2P contribute over 80% traffic, due to the prevalence of video applications...
Internet's continual and rapid evolvement in scope and complexity impedes our understanding on it. Considering the data variety caused by user behaviors, and locations of geography or the Internet, studying own trace is an effective method of learning the Internet. To this end, we have conducted traffic measurements at our campus, and study the captured traces. Several analysis results are presented...
Time synchronization is critical in distributed network system. A variety of network protocols, middleware and business applications rely on proper time synchronization across the computational infrastructure and depend on the clock accuracy. The “Network Time Protocol” (NTP) is the current widely accepted standard for synchronizing clocks over the Internet. In order to reduce access frequency to...
The Internet of Things can bring fundamental changes to tangible goods for E-commerce, such as production, warehousing, procurement, transportation, distribution, consumption and recovery of the whole logistics process, realize the full tracking and tracing of goods, thus greatly enhance E-commerce logistics services quality. This paper deeply studies how the Internet of Things to optimize logistics...
In recent years, GIS(Geographic Information System) develops rapidly, and it is applied in various industries. But the application of GIS in electronic commerce is far behind its application in other areas. Using the programmable interfaces provided by Google Maps, we created an online shopping system which has the map functions to probe the application of GIS in electronic commerce. The system adopts...
This paper presents a measurement-based study of Xunlei, a young but increasingly popular P2P application currently mainly used in China. Due to its proprietary protocols and data encryption, packet-level data was analyzed in order to infer the network architecture and the superior download behavior, Xunlei's main key to success. We identify Xunlei's core-server layer with a clear division of tasks...
The purpose of this study is to determine the most efficient service provider of the real estate online marketing. Nowadays, with the rapid development of residential real estate market, real estate online marketing has been widely applied, and its efficiency evaluation has been an important task in the process of project. Our study first creates the index system and uses this index system to filter...
As one of the most popular applications in China, Xunlei's excellent performance attracts us to pay more attentions to its system mechanism. The issue of bandwidth theft in Xunlei is one of our focuses. Although its proprietary nature and its use of data encryption hinder our studies of Xunlei to some extent, we analyze and evaluate behaviors of bandwidth theft in Xunlei based on our measurements...
We compared UDP and TCP traffic in several traffic traces collected from different networks and geographical locations, at different times. We find that TCP still dominates in terms of packets and bytes, but UDP is now often responsible for the largest fraction of flows on a given link. A port-based analysis suggests that the recent increase in UDP flows on the traces analyzed stems mainly from P2P...
The present research studied the effects of page scrolling style, reading task and column on the efficiency of text reading from a monitor. The results indicated that participants could finish their reading task more quickly when the task was information search than when it was reading comprehension and that they read texts more efficiently in one-column format than in two-column format. However,...
