The growing complexity of content delivery networks: Challenges and implications for the Internet ecosystem

Since the commercialization of the Internet, content and related applications, including video streaming, news, advertisements, and social interaction have moved online. It is broadly recognized that the rise of all of these different types of content (static and dynamic, and increasingly multimedia) has been one of the main forces behind the phenomenal growth of the Internet, and its emergence as essential infrastructure for how individuals across the globe gain access to the content sources they want. To accelerate the delivery of diverse content in the Internet and to provide commercial-grade performance for video delivery and the Web, Content Delivery Networks (CDNs) were introduced. This paper describes the current CDN ecosystem and the forces that have driven its evolution. We outline the different CDN architectures and consider their relative strengths and weaknesses. Our analysis highlights the role of location, the growing complexity of the CDN ecosystem, and their relationship to and implications for interconnection markets.

An integrated production–distribution model for the dynamic location and allocation problem with safety stock optimization

The design and management of a multi-stage production–distribution system is one of the most critical problems in logistics and in facility management. Companies need to be able to evaluate and design different configurations for their logistic networks as quickly as possible. This means coordinating the entire supply chain effectively in order to minimize costs and simultaneously optimize facilities location, the allocation of customer demand to production/distribution centers, the inbound and outbound transportation activities, the product flows between production and/or warehousing facilities, the reverse logistics activities, etc.Full optimization of supply chain is achieved by integrating strategic, tactical, and operational decision-making in terms of the design, management, and control of activities. The cost-based and mixed-integer programming model presented in this study has been developed to support management in making the following decisions: the number of facilities (e.g. warehousing systems, distribution centers), the choice of their locations and the assignment of customer demand to them, and also incorporate tactical decisions regarding inventory control, production rates, and service-level determination in a stochastic environment. This paper presents an original model for the dynamic location–allocation problem with control of customer service level and safety stock optimization. An experimental analysis identifies the most critical factors affecting the logistics cost, and to finish, an industrial application is illustrated demonstrating the effectiveness of the proposed optimization approach.

The gap not only closes: Resistance and reverse shifts in the digital divide in Russia

The reduction of the digital divide due to the availability of the Internet and the improvement of skills is accompanied by reverse and resistance trends associated with the influence of socio-demographic and economic characteristics of users. In this paper, we estimate the volume and dynamics of the digital divide in access and use of the Internet in Russia by key social groups according to a longitudinal survey for 2008–2018. We found that along with the reducing of the digital divide, its gaps still remain. The greatest polarization is associated with the income, age, and type of residence of the respondents. The most vulnerable social groups on access to ICTs and Internet use are the low-income, the elderly, citizens with disabilities, and those living in rural areas. The reverse shifts in the digital divide were recorded mainly in relation to the Internet usage by age between the middle-age and youth and by gender. In addition, we pointed out the most resistance social groups to reduce the digital divide in the period under review, in particular, by income and type of residence of the respondents. The findings contribute to an understanding of the dynamics and social consequences of the digital divide and can be taken into account in social policy and measures.     

论“共主体”营销话语的建构与践行——关于现代营销近视症的矫治研究

本文针对当前营销理论和实践存在的"外形化"问题,梳理了莱维特提出营销近视症后的营销理论发展进路,得出该近视症并没有得到根治而且有新变异的论断和具有主体中心论特征与弊端的现代营销近视症;认为要根治该近视症,首先应克服"现代营销者研究现代营销"以及由此产生的"营销研究的近视症"局限,以营销研究者的身份、在跨学科和方法论高度与层面去寻求突破性思路和方法。基于这种认识,本文萃取和应用"后现代性"、"主体间性"与"网络嵌入性"等多学科话语作为矫治这种营销近视症的创新方法,重构了具有"消解对立、善待他者、与他者网络化互嵌共生"意蕴的共主体营销新话语,并论述了践行这种营销新话语的方式、机理和愿景。     

Understanding B2B and the Web: the acceleration of coordination and motivation

This paper explores business-to-business (B2B) marketing on the Internet, and how the confluence of the two may transform the B2B landscape. Specifically, it discusses the notion of linkage value to demonstrate why the B2B phenomenon on the Internet is so significant. It then considers the mechanisms and enablers that have made the Web such an important B2B marketing channel. It also explores how the Web can reduce transaction costs, thereby facilitating more efficient exchanges and markets. The concepts of links and nodes are then introduced and the processes of disintermediation, reintermediation, disaggregation and reaggregation are explored. Finally, Web B2B configurations are considered by way of a model that describes four archetypal configurations, and the factors that are antecedent to these modes and how the Web may influence them.
