Abstract
Purpose
As the storage and processing requirement of digital information is increasing on the cloud, it is very difficult for the single cloud provider (CP) to meet the resource requirement. Multiple providers form a federation for the execution of users’ requests. For the federated cloud, this paper aims to address the issue distribution of users’ request for resources and revenue among the providers by offering fair and stable distribution models for the federated cloud.
Design/methodology/approach
This paper uses cooperative game (CG)-theoretical models, i.e. Shapley–Shubik power index (SSPI) and Banzhaf power index (BPI) for distribution. Performance is analysed using variance and monotonicity using a case study.
Findings
Numerical analysis is done using two scenarios. Monotonicity is evaluated. Results show that SSPI performs better as compared to BPI in terms of fairness accuracy and the framework provide the fair distribution of revenue among providers in the federated cloud.
Research limitations/implications
The proposed framework works efficiently under the specific defined conditions.
Social implications
Paper provides the fair distribution. It assist the centralised cloud exchange in managing the users’ request in such a way every CPs, in the federated cloud will get an equal chance of serving the users’ request. The framework also provides the stable federation. Proposed work provides less rejection rate of users’ request. Finally, it assists the providers in increasing their profits in the federation.
Originality/value
This paper presents a CG theoretic-based framework for the distribution of resources required and revenue. The framework analysed the performance of distribution models by considering the variance and monotonicity for multiple users’ requests.

Abstract
Purpose
The purpose of this paper is to review the prosecution by US authorities of Zhongxing Telecommunication Equipment (ZTE) Corporation for its violation of sanctions against the sale of systems to Iran and North Korea; the violation of the plea agreement; and, following presidential intervention, the imposition of a further fine and restructuring of its management.
Design/methodology/approach
An analysis of the materials used in court proceedings and speeches by officials in the case against ZTE
Findings
The US president intervened in a quasi-judicial matter in which a foreign firm had violated US sanctions that he had supported to lessen the penalties it faced. The firm had also violated its plea agreement. This personal intervention weakened enforcement of US sanctions on human rights and weapons of mass destruction (WMD). However, it revealed the excessive reliance of Chinese manufacturers on US-domiciled suppliers of semiconductors and software.
Research limitations/implications
Neither was access to Chinese documents possible nor would it have been practicable to interview managers at ZTE.
Practical implications
Enforcement of US sanctions on the sale of telecommunications equipment have now been moved from strict enforcement on matters of human rights and WMD into political, trade and even personal negotiations with the US president.
Originality/value
A first analysis of a telecommunications sanctions case.

Abstract
Purpose
The purpose of this paper is to evaluate the operational performance of industrial park infrastructures in Germany to find first indications for cost saving potentials.
Design/methodology/approach
Between 2006 and 2007, six chemical parks and chemical related industrial parks in Germany participated in a benchmarking study with focus on operation and maintenance of buildings, communication infrastructures and traffic infrastructures. Based on data analysis in combination with workshops, numerous key performance indicators were defined and calculated.
Findings
To compare the different complexities of the analysed infrastructures, the most important key performance indicators were adjusted using correction factors defined and verified during the workshops. This made a discussion based on comparable and comprehensible figures possible which increased the acceptance and applicability of the benchmarking methodology. The benchmarking results showed large differences in performance levels, indicating that there are significant cost saving potentials in some industrial parks.
Research limitations/implications
The comparability may remain limited due to the partly insufficient availability of data from the participants. Other limitations are due to the small number of investigated industrial parks and the focus of the benchmarking study on Germany.
Originality/value
The developed benchmark and best practice methodology is well suited to evaluate best practice in the field of industrial park infrastructures. It is important for industrial parks to understand the individual performance level and to adapt best practice in all areas.

This paper aims to study network effects and the impacts on market structure in the specific context of China's network industries.
Abstract
Purpose
This paper aims to study network effects and the impacts on market structure in the specific context of China's network industries.
Design/methodology/approach
This paper is organized in the mode of “concept‐model analysis‐empirical examination”. Starting from the concept of “network effect”, it is then extended to the theoretical analysis of market structure and the examination of China's representative network industries.
Findings
The data for China's representative network industries produce mixed findings. Some prove the theoretical estimation quite well, while others do not follow the theoretical conclusion so closely.
Research limitations/implications
The data for China's network industry are relatively limited. The depth of the data is especially inadequate, which prevents more systematic econometrical analysis.
Practical implications
The paper can serve as a reference for private decision makers of network industries and for regulators with antitrust concerns.
Originality/value
This paper may be the first of its kind to study the market structure of China's network industries from the perspective of network effects theory. It could be a good reference for those interested in learning the current status of China's network industries.

Abstract
Purpose
Logistics sector is recognized as one of the core enablers of the economic development of a nation. However, inefficiency in logistics operations impedes the achievement of intended targets by increasing the cost of doing business. Also, it is difficult to improve the efficiency of a country’s logistics operations without a metric for evaluating and understanding logistics capabilities and efficiency. Therefore, the present study has developed In-country Logistics Performance Index (ILP Index) to propose a benchmarking tool to measure the in-country logistics competitiveness, particularly in the setting of emerging economies, i.e. India.
Design/methodology/approach
This study has developed a unified index using principal component analysis and quintile approach. In addition, the proposed index relies on several dimensions that are developed and illustrated using quantitative secondary panel data.
Findings
The findings of this study reveal that the quality of infrastructure, economy, and telecommunications are the three most important dimensions that may significantly support the growth of the transportation and logistics sector. The results reveal that Gujarat, Tamil Nadu, and Maharashtra are the top performers whereas, Bihar, Jharkhand, and Jammu and Kashmir scores the least due to the insufficient logistics infrastructure as compared to other Indian states.
Originality/value
Given the extensive focus on international-level logistics index (like World Bank’s LPI) in the existing literature, this study intends to develop in-country logistics index to evaluate the logistics capabilities at the regional and state level. In addition, unlike prior studies, this study utilizes quantitative secondary data to eliminate cognitive and opinion bias. Moreover, this benchmarking tool would assist decision-makers in idealizing standard practices toward sustainable logistics operations. Additionally, the ILP index could serve the international investors in crucial decision-making, as it provides valuable insights into a country’s logistics readiness, influencing their investment choices and trade preferences. Finally, the proposed approach is adaptable to measuring the overall performance of any other industry/economy.

Abstract
Purpose
The purpose of this paper is to examine economic debates over the conception of barriers to entry and speculates which definitions can be applicable to the telecommunications industry, more specifically, the residential broadband market. Also, it seeks to clarify the various industrial factors that could prevent or mar the success of entry into the residential telecommunications market and it also seeks to introduce an analytical framework that can be adopted for evaluating the barriers to entry.
Design/methodology/approach
The approach takes the form of a literature review.
Findings
It clarifies the various industrial factors that could prevent or mar the success of entry into the residential telecommunications market and introduces an analytical framework that can be adopted for evaluating the barriers to entry.
Originality/value
Although market entry barriers are crucial industrial factors that influence the market share and profit of firms already in the market, very little research has specifically examined barriers in the telecommunications and broadband industry.

Abstract
Purpose
The purpose of this paper is to set out the history and content of the European Commission's Recommendation on the regulation of next generation access networks, published in September 2010. The aim is to assess the Recommendation in terms of its likely impact on harmonisation and certainty of regulation within the European Union and on investment and competition.
Design/methodology/approach
The approach adopted is to review the European Commission's Recommendation from the standpoint of regulatory economics.
Findings
The publication in September 2010 of the Recommendation on the regulation of next generation access networks completed a process which had begun two years and two drafts previously. The paper sets out the background to the decision to prepare a Recommendation for national regulators supervising the installation of fibre based networks, where the fibre might go either to the premises (FTTP) or to the street cabinet (FTTC). It also describes the development of the Recommendation from the first draft in September 2008 to the final draft in September 2010. It concludes that the delay in issuing the Recommendation created an interval in which national regulators pursued their own diverse policies, to the detriment of harmonisation. In terms of investment and competition, the successive drafts appear to have diminished pressure on competitors to build their own infrastructures, with consequential effects on the likely form of competition. Finally, a degree of regulatory uncertainty has been created in member states where the regulator has pursued in its market reviews of fibre access products remedies which are at odds with the Recommendation.
Originality/value
This is an early appraisal of a European Commission Recommendation which is likely to have a significant impact on European communications policy and regulation.

Abstract
Purpose
Global commerce demands flexibility in when and how work gets done, as modern businesses increasingly require real‐time responses to partners and customers. With low costs, companies look to mobility as a way to speed responsiveness and increase the personalization of customer service offerings. Mobility is a key element of networking allowing enterprises to unlock their business process from fixed points. A unified approach to enterprise mobility delivers integrated wired/wireless networking, mobile extensions to unified communications, geographic, and end‐point independent network access and location services as major architectural components. As a consequence, this paper aims to focus on a converged architecture that spans wired and wireless networks to enable a seamless delivery of integrated services across the enterprise.
Design/methodology/approach
This paper builds a framework to facilitate a continuous delivery of voice services. It also examines an architecture that traverses wireless local area network and local area network. And, proposes a mathematical model of the services delivery in order to analyze network behavior as a response to the new services introducing.
Findings
The authors constructed a service scenario framework and also put forward an analytical model of the services delivery for analyzing network behavior response for the inclusion of new services. They also evaluated a network infrastructure, services, and applications, including the prospective converged services, as well as the technology for the transition to future services.
Originality/value
This paper contributes to the development of seamless services delivery model for providing enhanced business services to the enterprise customers along with the ability to migrate more tightly.
