Internet interconnection is the glue that holds the Internet together via bilateral network interconnection agreements of best effort (i.e. non-assured) quality. This study provides qualitative analysis and assessment of the multidimensional impacts of the recent proposals of introducing Assured Service Quality (ASQ) in the Internet interconnection (IC) market. The analysis focuses on the impacts in three distinct, though strongly interrelated aspects: Business, Socioeconomic and Regulatory. Methodologically, the impacts are identified through a focus group which involved representatives from 17 European organizations. Exploring how these complementary impacts may affect the ASQ offer is fundamental for envisioning the Internet evolution and for setting appropriate governance policies. This study identifies and discusses the expected impacts, thus shedding light on the key implications of assured quality Internet interconnection.

“…While many test participants had notably lower degrees of QoE in the wireless test cases, others actually perceived the wireless to be much better. Sackl et al also addressed the Willingness to Pay (WTP) [55,56], as labels indeed affect the customers' monetary decisions. User expectations were also in direct focus of a subsequent work [1], due to the socio-psychological reasons mentioned earlier.…”

Comparison of HD and UHD video quality with and without the influence of the labeling effect

The past decades have shown a steady rise in the pixel resolution of digital visualization technologies. New TVs and computer displays available on the consumer market are commonly UHD/4K, and 8K recently started appearing in the commercial world. The added value of such higher resolution is not only indicated by the purported level of visual performance, but also by the labels that emphasize the devices' properties, especially the resolution. However, the genuinely perceived difference between two resolutions, such as HD and UHD, may not have the same effect on user experience as the labels attached to the devices or sequences themselves. In this paper we present four subjective studies in which we investigated the influence of the labeling effect in the context of HD and UHD video. Subjects were shown pairs of either HD or UHD video sequences and had to determine whether there was a difference in quality between the sequences. Two of the subjective tests involved labels in these paired comparisons, indicating to the subject which sequence was which, while the other two tests excluded these labels. For both test sets with and without labels, one test used a 3-point comparison scale for the subjective assessment of visual quality, while the other used a more fine-grained 7-point scale. Our findings show that the sole inclusion of quality labels can strongly impact subjective rating behavior and the overall opinion on UHD quality; also, visual differences between HD and UHD video were rarely noticeable by the subjects. Standards and recommendationsAs with most technologies finding widespread use among the consumers, there are standards that govern how a technology is to be developed, evaluated, and integrated with other technologies. Standards or international recommendations are provided for that interoperability. Among the most relevant international standards on the topic of UHD are documents from the International Telecommunication Union's telecommunication and broadcasting sectors (ITU-T and ITU-R).While ITU-R Rec. BT.709 addresses HDTV (i.e., TV up to 1080p resolution), Rec. BT.2020 [3] covers UHD and the corresponding specifications of dynamic range, color gamut and primaries, bit depths, frame rates, and pixel resolutions. Additional recommendations include Rec. BT.1769 which specifies parameter values for large screen digital imagery and how to design a system that gives viewers visual experiences of a high-sensation of reality-which UHD was also developed for.Subjective quality assessment tests are typically carried out in a rigorous fashion: users are placed in a dedicated testing room with specific lighting conditions and a certain viewing distance to the screen. Guidelines in ITU-T Recommendations P.910, P.911, and P.913 as well as ITU-R Rec. BT.500-13 may be applied in those tests. When subjectively evaluating the quality of UHD systems, the aspect of viewing distance plays a crucial role. Typically, for HDTV applications, human testers are seated at a distance of about 3 H to the TV, where H is the ...

“…We focus on the scenario combining broker and carrier roles. As mentioned earlier, this cloud service/ network bundle may favour the telcos among other cloud competitors in a market where service accessibility and users demand focus on the connectivity quality beyond the service features themselves when brokering cloud services. Offer / service refers to the benefits that a company's value proposition brings to its clients through solving their problems with the company's offering of services or products.…”

Cloud computing represents a major change in how resources of information technology are delivered and consumed and will influence the telecom industry, its future services, business offerings and economics of the telecommunication. New revenues potentials from mediating cloud‐based services are however less discussed, as well as the commonly accepted and completed methodology for this purpose is lacking. The objective of this paper is to clearly identify recommended roles for telecommunication companies (telcos) in the cloud value chain and to present a model for assessing and optimising innovative business opportunities. In particular, we show how the portfolio theory of modern investment science supports risk management in operation of telecom company‐based cloud carriers for service brokering.We recommend a combined broker and carrier role to be a preferred cloud business model for a telco. Such combination is expected to represent the best value proposition for competing against cloud providers and ICT integrators. Further quantitative analysis indicates significant business benefits from differentiating and optimising provision of carrier grade and best effort network connectivity types for a given bundle of cloud services. This implies an efficient use of telco assets and satisfies an increasing demand for network performance in the business market.The novelty of the paper is the developed quantitative optimisation model as well as the analytical identification of the preferred telco role in cloud value network. Practical application of the research may improve dimensioning of technological assets, leading to higher cost efficiency and possibly higher degree of customer satisfaction.
