The growth of the Internet with its increasing levels of traffic, more ambitious applications and the convergence of communication technologies results in poor quality of service. New technologies such as those discussed in this paper have been developed to aid in introducing quality of service to the Internet. However, those efforts may seem to be in vain due to the heterogeneous nature of IP-based networks. This paper suggests an integrated approach to provide end-to-end quality of service on the Internet based on the use of programmable interfaces. The need for dynamic modification of policies and configurations within IP routers and switches is already beginning to emerge and that functionality will help fulfill customers' demands for differentiated services.

Abstract Nowadays, companies are increasingly forced to fight against competition. The number of competitors on the market is constantly growing, and customer’s demands on the products offered by the companies are increasing. The role of customers on the market has changed in recent years. Customers are more active than before, i.e. they started to actively co-create value, so they stopped being passive to the purchase process. Organizations that make appropriate use of the increase in customer activity can count on large benefits for the company. One of the methods to increase competitiveness is continuous introduction of new technologies based on the Internet, which recently resulted in easier cooperation between customers and suppliers, making and settling transactions, coordination of orders in the supply chain thanks to e.g. solution supporting electronic exchange of EDI documents. Therefore, the development of information and communication technologies has significantly influenced the development of organization through its improvement. This paper presents the importance of new technologies for the customer that improve the process of its service in a selected clothing sales network in Poland.

New information and communication technologies are radically transforming the way that information and knowledge are disseminated and shared around the world. The digital divide between rich and poor countries is still persisting: more than 70% of the world’s Internet users are based in Europe and North America, where—in addition—more than 90% of the data on Africa are stored. Similar gaps persist between urban and rural areas and between men and women, especially in developing countries. Rural women usually have less access than men to information and new technologies (Huyer & Mitter 2003). Lack of information and access to education related to IT also limits women’s influence in their communities and their ability to participate in decision-making. When assessing the opportunities and risks of new technologies, it is essential to give attention to gender differences and to ensuring that women’s voice is heard so that technological developments can be sustainable in the way that best prevents them from increasing inequalities. Particularly gender factors are crucial to develop a sustainable concept of IT evolution. Our aim in this article is to show how the concept of gender and IT can be integrated in a wider conceptual framework of sustainability. First, we will explain the concept of digital divide from a global perspective and the importance to understand the gender dimension within this conceptualization. Concerns about the disparities between industrialized and developing countries, especially with respect to Internet access and use, have touched off a worldwide debate about the existence of a global digital divide. From a domestic perspective at a national level or even at a regional level thinking about the European Union for instance, the term digital divide has shown to have powerful symbolic weight, and hence to be a useful tool with which to mobilize political support for government programmes designed to bridge the gaps between so called “information haves” and “information have-nots.” The OECD defines the “digital divide” as “…the gap between individuals, households, business and geographic areas at different socio-economic levels with regard both to their opportunities to access information and communication technologies (ICTs) and to their use of the Internet for a wide variety of activities. The digital divide reflects various differences among and within countries.” (OECD, 2001, p. 5). Access to information and communication technologies is considered as the first stage to become an “information have.” However, access is not limited to the infrastructures: an important factor contributing to the digital divide is the extended and hegemonic use of English as access language in the Internet. This is one of the reasons for instance, why the Hispanics in the USA a lower access to the Internet show as Wilhelm (2000) argues. Moreover, even among “information haves” or in other words, among those having access to information through information technologies we can observe digital gaps. DiMaggio and Hargittai (2001, p. 4) refers for instance to the ability to evaluate the quality of information: “By ‘digital divide,’ we refer to inequalities in access to the Internet, extent of use, knowledge of search strategies, quality of technical connections and social support, ability to evaluate the quality of information, and diversity of uses.” This aspect is particularly related to the inequalities according to the educational level of the “information haves.” Furthermore, when carried to the international level, the term “digital divide” arguably misconstrues the issue and is unduly pessimistic. For example, the term directs our attention to relative inequalities in the distribution of information age resources, when what really matters to the quality of life in a given country is its absolute level of resources and the efficacy of the institutional order in redistribution and social justice. Qureshi (2005, p. 1) refers to the results of a recent study about the digital divide showing that “it is access to information, services, and expertise through access to the network, combined with ICT skills that contribute to economic growth and a decrease in this gap.” Instead of fixating on the existence of a divide, it would be far better to focus our attention on the “global digital opportunity,” because that is what really confronts us today, an unprecedented opportunity to move swiftly up the path towards global digital development. From a gender perspective, it is important to improve the access of women, particularly women in underdeveloped countries and rural areas to knowledge and information through IT, but it is also important that women participate in the design and production of IT. We argue that the digital divide must consider also the gap regarding IT shaping. Shaping IT means nowadays in much extent shaping society and nature and thus we plaid for a concept of sustainable information society with a participatory approach that allows the integration of excluded perspectives and moving beyond consumerism fixations taking local voices and the co-evolution of nature and society as a point of departure. Particularly women’s perspectives excluded in great extent through gendering processes must be taken into account as they reinforce other embedded inequalities factors such as education or age. Understanding gendering processes within the shaping of IT and society is crucial in the concept of sustainable information society. However, IT development constitutes also a complex co-evolution of nature and society in different world regions. Particularly sustainability scholars have attempted to define these both basic co-interacting spaces. In the next section, we show an overview of the basic assumptions of sustainability that have lead to a more focused concept of sustainable information society.

The development of the modern world is very complex and rapid, and the process is characterized by high rates of development of information and communication technologies. The Internet space is a means of searching and obtaining information, as well as a medium for communication, virtual interaction, and has a significant impact on the formation of stereotypes of behavior of the young generation, as well as ideals, spiritual values, personal and social worldview. The article identifies the positive aspects of the development of cyberspace by young people, and also notes the threats and barriers to cyber socialization for modern youth. The necessity of conducting psychological and pedagogical research on cyber socialization is actualized, a conclusion is made about the use of new technologies for the purpose of positive cyber socialization of the younger generation.

<p>Microwave backhaul networks are the dominant technology used to connect together access and core networks for their flexibility and cost-effectiveness in deployment. Unfortunately, microwave backhaul networks are susceptible to interference and are statically managed leading to poor Quality of Service (QoS) in the form of high delays and loss as well as being inefficient on energy. The use of Software Defined Networking (SDN) is proposed to address these problems by dynamically managing resources to work around the interference and remove static allocations. Two new algorithms, CUT and OptiCUT were designed to compute an optimal topology, to minimise loss and delay while at the same time reducing power consumption.</p>
