Remote Communications

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.

AbstractThe mass rapid transit (MRT) is the largest transport infrastructure project under the national key economic area (NKEA) in Malaysia. As urban rail is anticipated to be the future spine of public transport network in the Greater Kuala Lumpur city, it is important to mainstream climate change mitigation and public health benefits in the local transport development. This study quantifies the health co-benefits in terms of mortality among the urbanites when the first line of the 150 km MRT system in Kuala Lumpur commences by 2017.Using comparative health risk assessment, we estimated the potential health co-benefits from the establishment of the MRT system. We estimated the reduced COA total of 363,130 tonnes of COThe implementation of the MRT system in Greater Kuala Lumpur could bring substantial health co-benefits to both the general population and the MRT users mainly from the avoidance of mortality from traffic injuries.

The Global Financial Crisis

In Western liberal democracies the planning of mega transport infrastructure projects is guided by public interest claims typically expressed through legislation and political mandates. But with the infrastructure boom being observed in many cities since the Global Financial Crisis, and the need to address unprecedented levels of urbanisation, the level of politicisation directed at infrastructure projects draws attention to how the public interest is treated in the planning and management of complex mega transport infrastructure projects in diverse local contexts. Looking to Sydney, an advanced neoliberal city building the largest transport infrastructure project in Australian history, we examine how public interest is asserted in a way that reinforces legitimacy of the process and consensus for the project. Under these conditions, planners fail or are unwilling to raise additional or new public interest issues. The vagaries of public interest mean that in being open to interpretation the public interest can be easily captured by the interests of capital and of ruling politicians. This raises important questions for urban studies about the role governments and, in particular, public-sector planners can play in advocating for actually existing public interest issues such as environmental sustainability without it amounting to just rhetoric with no follow through.

The main task of country economy modernizing aimed to improve its competitiveness and sustainability is the corresponding infrastructure creation. This problem solution is possible only through the joint efforts of state and private business. In this article the common and specific factors that affect the transport infrastructure project management are revealed on the basis of infrastructural project managing experience analysis, the principles of public-private partnership (PPP) as the format of such projects� realization are systematized and developed taking into account their characteristics. The offers directed on improvement of organizational and economic mechanism of infrastructural project management in the railway infrastructure sphere in the PPP model (the life-cycle contract) are developed.

Private Financing

A method to identify the attractiveness for private financing of a transport infrastructure project is presented. The objective of the method is to assist the public sector in identifying the attractiveness of a transportation infrastructure project for private financing, highlighting the factors that tend to reduce such attractiveness and providing the means to examine the viability of alternative risk-allocation scenarios related to risks undertaken by the state or private sector. The method allows for the simulation of the private sector’s attitude toward risk, employing practices of risk assessment in investments. Its innovation lies in how the whole process is structured so that participants understand beforehand whether an agreement can be concluded and which factors involved are critical. A key property of the method is the ease by which priorities of different risk components are synthesized into a hierarchical form through pairwise comparisons. This method, although targeted primarily for the public sector, could assist both private and public stakeholders investing in transport infrastructure projects (termed private-public partnerships) to reach an agreement. Basically, it is an interactive process characterized by the conflicting objectives and judgments of both public and private sectors.
