The Web

The recent increase in popularity of the Web has led to a considerable increase in the amount of Internet traffic. As a result, the Web has now become one of the primary bottlenecks to network performance and web caching has become an increasingly important issue. Web caching aims to reduce network traffic, server load, and user-perceived retrieval delay by replicating popular content on caches that are strategically placed within the network. Browser caches reside in the clients’ desktop, and proxy caches are deployed on dedicated machines at the boundary of corporate network and Internet service providers.

Video on demand (VoD) services such as YouTube have generated considerable volumes of Internet traffic in homes and buildings in recent years. While Internet service providers deploy fiber and recent wireless technologies such as 802.11ax to support high bandwidth requirement, the best-effort nature of 802.11 networks and variable wireless medium conditions hinder users from experiencing maximum quality during video streaming. Hence, Internet service providers (ISPs) have an interest in monitoring the perceived quality of service (PQoS) in customer premises in order to avoid customer dissatisfaction and churn. Since existing approaches for estimating PQoS or quality of experience (QoE) requires external measurement of generic network performance parameters, this paper presents a novel approach to estimate the PQoS of video streaming using only 802.11 specific network performance parameters collected from wireless access points. This study produced datasets comprising 802.11n/ac/ax specific network performance parameters labelled with PQoS in the form of mean opinion scores (MOS) to train machine learning algorithms. As a result, we achieved as many as 93–99% classification accuracy in estimating PQoS by monitoring only 802.11 parameters on off-the-shelf Wi-Fi access points. Furthermore, the 802.11 parameters used in the machine learning model were analyzed to identify the cause of quality degradation detected on the Wi-Fi networks. Finally, ISPs can utilize the results of this study to provide predictable and measurable wireless quality by implementing non-intrusive monitoring of customers’ perceived quality. In addition, this approach reduces customers’ privacy concerns while reducing the operational cost of analytics for ISPs.

Internet traffic volume is increasing, and this causes scalability issues in content delivery. Information-centric network has been introduced to support this increase in Internet traffic through caching. While collaborative caching in information-centric network is a crucial feature to improve network performance and reduce delivery costs in content distribution, the current pricing strategies on the Internet are not incentive compatible with information-centric network interconnection. In this paper, we focus on the economic incentive interactions in caching deployment between several types of information-centric network providers (content provider and Internet service provider). In particular, we develop game-theoretic models to study the interaction between providers in an information-centric network model where the providers are motivated to cache and share content. We use a generalized Zipf distribution to model content popularity. We formulate the interactions between the Internet service providers and between the content providers as a noncooperative game. We use a Stackelberg game model to capture the interactions between the content provider and Internet service providers. Through mathematical analysis, we prove the existence and uniqueness of the Nash equilibrium under some conditions. An iterative and distributed algorithm based on best response dynamics is proposed to achieve the equilibrium point. The numerical simulations illustrate that our proposed game models result in a win-win solution.

Abstract:The internet developed for the first time in Indonesia in the early 1990s. Starting from the pagayuban network, it is now expanding without boundaries anywhere. A survey conducted by the Indonesian Internet Service Providers Association (APJII) said that the number of internet users in Indonesia in 2012 reached 63 million people or 24.23 percent of the country's total population. Next year, that figure is predicted to increase by close to 30 percent to 82 million users and continue to grow to 107 million in 2014 and 139 million or 50 percent of the total population in 2015. million people. This matter also results in political communication with the internet media, or is often said to be cyber politics. Cyber politics in Indonesia has faced growth in recent years. There are many facilities that support the growth of cyber politics, such as Facebook, Twitter, mailing list, YouTube, and others.Keywords: Cyberpolitik, Internet  Abstrak:Internet berkembang pertama kali di Indonesia pada awal tahun 1990-an.

Customer Satisfaction Index

This study aimed to analyze the customer experience seen from the level of actual performance and the level of importance of services provided by internet service providers PT. XYZ in Makassar City. Variables and attributes issued by TM Forum GB 912 consisting of Customer Management, Fulfillment, Assurance, and Billing, are used to analyze the performance provided by customer service in the field. The analysis technique will be carried out using the Importance Performance Analysis and Customer Satisfaction Index consisting of quadrant analysis and gap analysis used to investigate customer satisfaction and identify variables whose performance is deemed to need improvement. Data were collected using a platform-based questionnaire application from 100 respondents selected using random sampling techniques. The results showed that customers were satisfied with the performance and quality of services provided. The customer satisfaction index value obtained by CSI analysis shows a value of 82.006%. In conclusion, that the Fulfillment variable is a service variable that is considered the most important customer and requires improvement because its performance is still relatively low. While the variables considered good and need to be maintained are the Billing variable.

Theoretical Insight

Tanulmányunk témája a netsemlegesség. Először magát a fogalmat definiáljuk többféle módon, majd a netsemlegességgel kapcsolatos törvényhozói, internet- és tartalomszolgáltatói, valamint felhasználói kihívásokat, problémákat és válaszokat mutatjuk be. Számos szerző szerint az internet legnagyobb, immár tradicionális értéke a nyíltság, sokszínűség, tartalomgazdagság, tértől és időtől független társadalmi és perszonális kommunikációba való szabad belépés és a szabad verseny lehetősége. A netsemlegesség mellett és ellen felhozott érvek bemutatását is ezek a szempontok alapján tesszük. Kiemelt szerepet kap a netsemlegesség megsértésének kategorizálása is. Tanulmányunkban közlünk egy törvényalkotási kronológiát, mely az USA-ra, az EU-ra és Kelet-Ázsiára fókuszál, illetve ismertetjük a BEREC 2011-es felmérésének az EU-ban alkalmazott, internetszolgáltatói gyakorlatra vonatkozó eredményeit. A munkát az Internet.org kezdeményezést vizsgáló esettanulmány zárja, végül ezt követik a jövővel kapcsolatos kérdések, és néhány lehetséges válasz. --- Net neutrality - definitions and the standpoints of legislators, content providers, Internet service providers and users This article examines the topic of net neutrality. Firstly, it provides us with a theoretical insight and several definitions. Then it presents the issues and challenges legislators, ISP’s, content providers and users face. Several authors state that the biggest virtue and value of Internet lies in open access, diversity, richness of content, free competition, and low barrier entry for users in order to participate in personal social communication. Our presentation of arguments pro and cons net neutrality will be built on the basis of these considerations. Priority will be given to the introduction of several categories of net neutrality violations. In our paper we will present a legislative chronology in the topic focusing on USA, EU and Korea-Japan as well as the findings of the 2011 BEREC survey. Finally we examine the Internet.org project. In the conclusion, the article offers several more issues to be discussed and provides some possible answers.
