AbstractAn important problem of network traffic is how to efficiently carry massive amounts of data traffic generated by Peer-to-Peer (P2P) services in high-speed and large-capacity optical access networks. P2P file-sharing traffic is regarded as one of the biggest bandwidth consumption in the world. Internet service providers can reduce the bandwidth burden in the feeder fiber by localizing the network traffic. In this paper, we propose an enhanced redirection strategy based on the optimized MPCP protocol (ERS-MPCP) to redirect the traffic into the access network and reduce the latency. A Markov chain is used for mathematical modeling. In the proposed strategy, we build a simulation platform for network simulation. Simulation results show that our strategy can improve the overall redirection success rate by up to 9%, thereby reducing the data traffic burden on the core network.

This paper presents recent research into P2P distribution of video that can be highly localized, preferably sharing content among users on the same access network and Central Office (CO). Models of video demand and localized P2P serving areas are presented. Detailed simulations of passive optical networks (PON) are run, and these generate statistics of P2P video localization. Next-Generation PON (NG-PON) is shown to fully enable P2P video localization, but the lower rates of Gigabit-PON (GPON) restrict performance. Results here show that nearlyallof the traffic volume of unicast video could be delivered via localized P2P. Strong growth in video delivery via localized P2P could lower overall future aggregation and core network bandwidth of IP video traffic by 58.2%, and total consumer Internet traffic by 43.5%. This assumes aggressive adoption of technologies and business practices that enable highly localized P2P video.

Purpose The rising proportion of internet users in Sub-Saharan Africa and the lack of analytical techniques, as decision support systems, in choosing among alternative internet service providers (ISPs) by consumers underpin this study. The purpose of this paper is to propose an approach for evaluating high-speed internet service offered by ISPs in a sub-Saharan African country. Design/methodology/approach Using a sample size of 150, pairwise comparisons of two ISPs along five criteria of cost, usability, support, reliability and speed were performed by ten person groups of university students working in various organizations in Ghana and undertaking an online Six Sigma Course. Geometric means were employed to aggregate the scores in 15 groups, and these scores were then normalized and used as input into an analytical hierarchy process grid. Findings The results show that consumers of internet services highly emphasize the cost attribute of internet provision in their decision making. On the other hand, it was realized that consumers least emphasize the support provided by ISPs in their decision making among alternative ISPs. Originality/value This study has sought to provide an analytical framework for assessing the quality of service provided by alternative ISPs in a developing economy’s context. The evaluating criteria in this framework also reveal the key consumer requirements in internet service provision in a developing economy’s environment. This, to a large extent, will inform the marketing strategies of existing ISPs in Ghana as well as prospective ones intending to enter the Ghanaian market. Besides, the National Communication Authority, a regulator of communication services provision in Ghana, will be informed about the performances of the ISPs along five performance criteria. This is expected to aid in their regulatory functions.

As Telecommunication has become a basic requirement of the today’s society there had been a vast increase of competition between the telecommunication service providers. Every service provider tries to cater the customers the best services for the lowest charges. Customers have the expectation of receiving the most recent technologies for the cheapest cost. Triple play (voice, data, content) is becoming everyone’s requirement today in communication. Voice over IP (VoIP) comes handy in considering Triple play. The design presents in the paper is an approach developed for a company that holds an Internet Service Provider (ISP) license from the Telecommunications Regulatory Commission of Sri Lanka (TRCSL) for island-wide coverage. The said company is a subsidiary of the leading Telecommunication provider of the nation. The problem faced here by the subsidiary is finding the capital cost to provide this highly exclusive IN (Intelligent Network) services to the customers in their initiation phase to cope with the existing competition. As an optimum solution, came up with the idea of accessing existing legacy PSTN core network of the leading telecommunication service provider which enhances most of the highly exclusive services. The system presented in the paper is a small model of an existing network that allows online billing facility for data calls as an IN facility.

Internet Neutrality

Internet neutrality—usually net(work) neutrality—encompasses the idea that all data packets that circulate on the Internet should be treated equally, without discriminating between users, types of content, platforms, sites, applications, equipment, or modes of communication. The debate about this normative principle revolves around the Internet as a set of distribution channels and how and by whom these channels can be used to control communication. The controversy was spurred by advancements in technology, the increased usage of bandwidth-intensive services, and changing economic interests of Internet service providers. Internet service providers are not only important technical but also central economic actors in the management of the Internet’s architecture. They seek to increase revenue, to recover sizable infrastructure upgrades, and expand their business model. This has consequences for the net neutrality principle, for individual users and corporate content providers. In the case of Internet service providers becoming content providers themselves, net neutrality proponents fear that providers may exclude competitor content, distribute it poorly and more slowly, and require competitors to pay for using high-speed networks. Net neutrality is not only a debate on infrastructure business models that is carried out in economic expert circles. On the contrary, and despite its technical character, it has become an issue in the public debate and an issue that is framed not only in economic but also in political and social terms. The main dividing line in the debate is whether net neutrality regulation is necessary or not and what scope net neutrality obligations should have. The Federal Communications Commission (FCC) in the United States passed new net neutrality rules in 2015 and strengthened its legal underpinning regarding the regulation of Internet service providers (ISPs). With the Telecoms Single Market Regulation, for the first time there will be a European Union–wide legislation for net neutrality, but not recent dilution of requirements. From a communication studies perspective, Internet neutrality is an issue because it relates to a number of topics addressed in communication research, including communication rights, diversity of media ownership, media distribution, user control, and consumer protection. The connection between legal and economic bodies of research, dominating net neutrality literature, and communication studies is largely underexplored. The study of net neutrality would benefit from such a linkage.

High-speed transceivers are receiving great interest due to the demand for huge data traffic and information storage capacities in the Big Data era. Recently, 100 Gigabit Ethernet (100GbE) has become an IEEE standardized data communication protocol. The 100G quad small form-factor pluggable (QSFP) transceiver is one of the key technological enablers in the high-speed optical networks. In this paper, we study the reliability current dependence for the four-lambda QSFP (4x25G) EML devices that are employed in the 100G QSFP transceivers. In order to meet the energy-efficient and environmental requirements, we develop a swift reliability test methodology that can provide fast, accurate reliability assessment to ensure robust long-term field performance. We discuss the acceleration factor and extrapolation for the energy-efficient reliability test.

Abstract The access network is developing towards large capacity, wide-coverage, and low delay, which puts forward higher requirements for network structure and data exchange performance of optical access network equipment. In this paper, we have designed a high-speed optical network device with 40/10G TDM-PON. To effectively solve the problem of network switching capability in high-speed data transmission, we propose a low delay large capacity switching algorithm, which minimizes the network switching delay. We model the network by integer linear programming and simulate the network based on OMNeT++. The simulation results show that the algorithm can effectively solve the problem of network switching delay in the high-speed network environment.

Basic Concepts

With the emergence of high-speed optical transmission, the pre-existing plesiochronous digital hierarchy (PDH) appeared unsuitable for achieving network synchronization, leading to the development of the synchronous optical network (SONET) and synchronous digital hierarchy (SDH) as the two equivalent standards for circuit-switched optical networks. Several bandwidth-efficient techniques were also developed to carry packet-switched data traffic over SONET/SDH networks, offering some useful data-over-SONET/SDH architectures. Subsequently, with the increasing transmission rates for SONET/SDH and Ethernet-based LANs, a convergent networking platform called optical transport network (OTN), was developed. With the ever-increasing volume of bursty data traffic, a standard for packet-switched ring networks, called resilient packet ring (RPR), was also developed for better bandwidth realization in optical fibers. In this chapter, we first present the SONET/SDH networks and the techniques for supporting the data traffic therein, followed by a description of the basic concepts and salient features of the OTN and RPR networks.

Backbone Network

Asynchronous Transfer Mode (ATM) is a high-speed networking technology designed to support real-time applications such as voice and video over both wired and wireless networks. This type of network is being used by medium-to-large organizations and the Internet service providers as backbone network to carry data traffic over long-distance with a guaranteed quality of service (QoS). The guaranteed QoS is achieved through a point-to-point link between end users. While the performance of ATM network over wired network has been studied extensively, the performance of real-time traffic over an ATM-Wireless extension has not been fully explored yet. It is useful to be able to compare the performance of ATM network with and without wireless extension against various network performance metrics to find out the effect of wireless extension on system performance.

Users and Internet service providers (ISPs) are constantly affected by denial-of-service (DoS) attacks. This cyber threat continues to grow even with the development of new protection technologies. Developing mechanisms to detect this threat is a current challenge in network security. This article presents a machine learning- (ML-) based DoS detection system. The proposed approach makes inferences based on signatures previously extracted from samples of network traffic. The experiments were performed using four modern benchmark datasets. The results show an online detection rate (DR) of attacks above 96%, with high precision (PREC) and low false alarm rate (FAR) using a sampling rate (SR) of 20% of network traffic.
