“…Despite progress toward more energyefficient appliances, overall levels of energy consumption continue to rise. For some devices and services, such as information and communication technologies, this is simply because of an increase in their total usage 1,2 . In other cases the redefinition of existing products, an example being SUVs, has resulted in an overall increase in energy consumption 3 .…”

The roles of users in shaping transitions to new energy systems

Current government information policies and market-based instruments aimed at influencing energy choices of consumers often ignore the fact that consumer behavior is not fully reducible to individuals making rational conscious decisions all the time. Rather, the decisions of consumers are largely configured by shared routines embedded in socio-technical systems. To achieve a transition towards a decarbonized and energy-efficient system, an approach is needed that goes beyond individual consumer choice and puts shared routines and system change at its center.Here, adopting a transitions perspective, we argue that consumers should be reconceptualized as users who are important stakeholders in the innovation process and are shaping new routines and enacting system change. We review the role of users in the building up of new decarbonized and energy-efficient systems and provide a typology of user roles.

“…The World Bank (2016) emphasizes that a country needs the 'analog complements' of favorable business environment, strong human capital, and good governances to observe the positive impacts of ICT. From the physical perspective, the development of ICT has a strong dependence on energy infrastructure (see, Van Heddeghem et al, 2014). Regmi and Pandey (2015) mention the Nepali ICT policies have neglected the energy-infrastructure nexus and warn that the energy consumption of existing Nepali ICT infrastructure has already become comparable to the transportation sector.…”

The relation between Internet and development rests on the preconditions of minimum access, quality, affordability and many more. Presenting the picture of access, quality, and affordability, we raise doubts that Nepali internet infrastructure in its present form has any contribution to economic development. The Nepali policy circle also has felt the necessity of proliferating Internet access and use. But we argue major targets of the Nepali ICT policies are detached from the reality and hence failure prone. The formulation of a robust ICT policy cannot bypass the analyses of actualities of the demand side. There is a dearth of detailed statistics of ICT access, use, and affordability in Nepal. We thus recommend the government should conduct a census of ICT access, use, and affordability that would help the formulation of more grounded policies.

“…The deployment of an m-MS configuration leads to some increased capital expenditure (CAPEX) that cannot be avoided. According to [22], a volume server costs less than 20000$ and in average consumes 222 W. We assume a cost of 5000 $ for each MS, and thus a CAPEX of m · 5000 $ for am m-MS configuration. Concerning operational expenditures (OPEX), we assume that the MSs are always on and we consider an average price per kilowatt-hour of 0.12 $/kWh [23].…”

Performance evaluation of video server replication in metro/access networks

et al. 2015

Internet traffic is increasingly becoming a media-streaming traffic. Especially, Video-on-Demand (VoD) services are pushing the demand for broadband connectivity to the Internet, and optical fiber technology is being deployed in the access network to keep up with such increasing demand. To provide a more scalable network architecture for video delivery, network operators are currently considering novel metro/access network architectures which can accommodate replicated video servers directly in their infrastructure. When servers for VoD delivery are placed nearer to the end users, part of the traffic can be offloaded from the core segment of the network, and the end users can experience better Quality of Service (QoS). While the deployment of caching systems for traffic offloading has been studied in the core network, no work has already investigated the potential performance gains by replicating the content in the metro/access segment of the network, even closer to the users. In our work, we will compare the performance of video server replication in different metro/access network architectures, i.e. a metro ring architecture and a tree-based architecture, by considering both active and passive technologies. We will evaluate using both simulative and analytical methodologies how content providers could benefit from the deployment of replicas of video servers in terms of blocking probability of the VoD requests.
