Infrastructure Sharing & Renewable Energy Use In Telecommunication Industry for Sustainable Development

Abstract: An important factor in green ICT challenges is to reduce the creation and emission of green house gases by all means. This chapter is concentrating on how telecommunication network operators could operate in a very much more environment friendly way by co-existing with their fellow operators by way of sharing infrastructure such as towers and power generators which will reduce the emission of green house gases. The chapter has described the impact and the magnitude of telecom infrastructure on the environment and the ways that can be practised in order to reduce the emission of green house gases. INTRODUCTION There is currently a worldwide concern about global warming caused specifically by the CO2 fuelled greenhouse effect and the role that pollution plays in weather and environment. Some scientists say global warming is also intensifying naturally depicted through extreme weather patterns like typhoons, floods, severe droughts, changes in sea levels and marine biology (Lu, H. 2009). Telecommunications is an essential component of development in today’s context and has one of the highest growth rates in the world. Therefore, “green” movement in the telecom industry is essential to us all. As energy prices soar, telecommunication network operators are even more motivated to scrutinize their expendi-

How to Change an Organization to Fit the Dynamic Environment: A Case Study on a Telecom Company of China

Abstract: This paper aims to explore how an organization changes to fit the dynamic environment. The paper's approach isa case study on a Chinese telecom company. Data have been collected through 2 questionnaire surveys as well as15 interviews. The results show that the organizational transformation of Anhui Telecom has enhanced the vigorof it and employees by stimulating dynamic capabilities and forming a high performance system, as well aspromoted the organizational capabilities, thus maintaining its sustainable competitive advantage. Nowadays,Chinese telecom industry is reconstructing. For each telecom operators, the organizational environment it faceshas changed. Unfortunately, very little research on organizational change of Chinese telecom industry has beendone. The study has significant reference for the business transformation of China Telecom.

Emulating Software-Defined Disaggregated Optical Networks in a Containerized Framework

Abstract: Telecom operators’ infrastructure is undergoing high pressure to keep the pace with the traffic demand generated by the societal need of remote communications, bandwidth-hungry applications, and the fulfilment of 5G requirements. Software-defined networking (SDN) entered in scene decoupling the data-plane forwarding actions from the control-plane decisions, hence boosting network programmability and innovation. Optical networks are also capitalizing on SDN benefits jointly with a disaggregation trend that holds the promise of overcoming traditional vendor-locked island limitations. In this work, we present our framework for disaggregated optical networks that leverages on SDN and container-based management for a realistic emulation of deployment scenarios. Our proposal relies on Kubernetes for the containers’ control and management, while employing the NETCONF protocol for the interaction with the light-weight software entities, i.e., agents, which govern the emulated optical devices. Remarkably, our agents’ structure relies on components that offer high versatility for accommodating the wide variety of components and systems in the optical domain. We showcase our proposal with the emulation of an 18-node European topology employing Cassini-compliant optical models, i.e., a state-of-the-art optical transponder proposed in the Telecom Infrastructure Project. The combination of our versatile framework based on containerized entities, the automatic creation of agents and the optical-layer characteristics represents a novel approach suitable for operationally complex carrier-grade transport infrastructure with SDN-based disaggregated optical systems.

On the changing face of service composition in telecom

Abstract: With the emergence of converged networks, Telecom operators are looking at composing Telecom functionality with 3rd party offerings to provide rich, innovative value-added services to their customers. In parallel, Internet Content providers like Google and Yahoo are rapidly moving towards adopting Web 2.0 technologies to enable a variety of end-user applications, and making them accessible to Telecom customers as well. This provides strong competition to similar paid-for services exposed on the Telecom portal. Telecom operators have recently started inspecting their service composition practises to see how it might be possible to exploit a Web 2.0 environment for rapid service creation. In this paper, we take a deeper look into service composition in a converged Web 2.0 Telecom ecosystem, consisting of Telecom functionality, 3rd party offerings and several categories of developers and users. We also propose a generic model for Telecom services in this ecosystem. Thereafter, we critically evaluate various existing service composition efforts for Telecom. Finally, we identify some open challenges and propose insights to address them.
