Modeling of request routing management on router for content delivery network

Abstract: A large amount of Internet traffic is organized through content delivery networks (CDNs). CDNs improve Internet access in terms of the response time and system throughput by mapping end-users to the nearest servers based on their locality, which known as request routing (RR). Most CDN systems use domain name servers (DNS) to redirect clients by issuing the IP address of the nearest server. Owing to the fact that DNS records have an expiration time (TTL), clients frequently have to contact name servers to update their IP addresses, which increases the connection delay. On the other hand, clients are demanding faster Internet connections. Because routers will be able to provide services in future networks, router-based RR has been proposed. In this paper, we study an analytical model of router-based RR. We present its architecture design and implementation, and show how router-based RR can be used to effectively redirect a clients’ request. Numerical analysis results demonstrate the effectiveness of router-based RR, which shows a 64.4% reduction of the response time for a client redirection.

This research examines the influence of learning with scientific debate strategy on academic performance throught the enhancement of mathematical competence of the student based MPA in the integral concept. The study design was a quasi-experiment that involving 200 students. The research instrument was mathematics competency tests with indicators: (1) Understanding of concepts; (2) Procedure fluency; (3) Strategic competence; (4) Adaptive reasoning; (5) Productive disposition. Data of mathematical competence enhancement were analyzed using Mann Whitney-U test. Data of pretest and posttest were analyzed by Kruskal-Wallis and ANOVA. Students who follow Integral Calculus learning with scientific debate strategy are significantly better than students who follow conventional learning. The Mathematical Prior Ability (MPA) factor in conventional class has a significant influence on academic performance throught the enhancement of student mathematical competence.The Mathematical Prior Ability(MPA) factor in theclass of scientific debate strategy did not have a significant influence on academic performance throught the enhancement of student mathematical competence

This paper reveals findings from a research that investigates the errors of students' understanding of integral concepts. Research design is quasi-experimental. Data collection is done through test instruments that are used for two purposes. The first objective is to find out the level of student error in solving problems. The second objective is to analyze and explain the results of student performance. Respondents of this study were two hundred students who took courses in Integral Calculus. Error level data were calculated using descriptive statistics and analyzed using Orthon theory. The findings show that the highest average level of student error in integral concepts based on learning strategies, early knowledge of mathematics, gender, and the educational background in the Scientific Debate class is arbitrary errors with mathematical competencies which are adaptive reasoning include: (1) estimating answers and process of solutions, and use patterns and relationships to analyze mathematical situations; (2) compile and test the conjecture; (3) follow the rules of inference and compile valid arguments, check the validity of arguments. In the conventional class, the level of highest error is Executive Errors with mathematical competencies are productive dispositions, namely the ability to always see mathematics positively, beneficially, and meaningfully.
