Root cause analysis of BGP updates is the key to debug and troubleshoot BGP routing problems. However, accurately inferring what is the cause of routing instability and where it originate is very hard. In this paper, we present a novel approach to locate the origin of routing instability by analyzing the relationship of the closed loops formed by intersecting the all the paths in path exploration...
Root cause analysis of BGP updates is the key to debug and troubleshoot BGP routing problems. However, inferring the root cause with high accuracy is challenge. Although correlating multiple vantage points is a validate method, how many vantage points are truly necessary to pinpoint the root cause is not resolved. In this paper, we propose a new method to explore two independent vantage points to...
Application of effective teaching model to course reform is top of concerns in college teacher education. Based on the importance of effective model of teaching, this study takes the course of “Education” as an example, analyses the problems of traditional model of teaching. Based on that, it introduces the successful experience of application of Blended-Learning in “Education” course reform, which...
A novel P2P traffic identification method based on the combination of naive Bayes and decision tables is proposed, which uses Fast Correlation-Based Filter (FCBF) algorithm to extract P2P flow characteristics, and utilises six DTNB (combination of naive Bayes and decision tables) combined with dynamic weighted integration method to set up a P2P flow detection model. Through experimental comparison...
The E-commerce website credibility has become a deciding factor in network marketing. The website credibility is a sense of trust and its intensity towards the E-commerce website is produced by the customer. According to the factors affecting the customer's assessment of the E-commerce website credibility, the evaluation indicator framework is divided into three level indicators, respectively: the...
Collaborative Filtering (CF) algorithms are widely used in a lot of recommender systems, however, the computational complexity of CF is high thus hinder their use in large scale systems. In this paper, we implement user-based CF algorithm on a cloud computing platform, namely Hadoop, to solve the scalability problem of CF. Experimental results show that a simple method that partition users into groups...
E-commerce is essentially based on trust. The level of enterprise Website credibility is an important basis for the Website browsers (or consumers) deciding whether to take further action or not, and will have a great influence on their purchase decision-making. This paper firstly defines the meaning of the enterprise Website credibility. Secondly, it divides the enterprise Website credibility into...
Today, e-commerce has achieved great developments. Consumers need visual interfaces to recognize patterns and to iteratively and dynamically compare attributes to get a match on what they need. This paper firstly discusses the relationship between information visualization and e-commerce Websites, secondly puts forward a number of key points used in the visual design of e-commerce Websites, thirdly...
