Deliverable JRA1.1: Evaluation of current network control and management planes for multi-domain network infrastructure

This deliverable includes a compilation and evaluation of available control and management architectures and protocols applicable to a multilayer infrastructure in a multi-domain Virtual Network environment.The scope of this deliverable is mainly focused on the virtualisation of the resources within a network and at processing nodes. The virtualization of the FEDERICA infrastructure allows the provisioning of its available resources to users by means of FEDERICA slices. A slice is seen by the user as a real physical network under his/her domain, however it maps to a logical partition (a virtual instance) of the physical FEDERICA resources. A slice is built to exhibit to the highest degree all the principles applicable to a physical network (isolation, reproducibility, manageability, ...). Currently, there are no standard definitions available for network virtualization or its associated architectures. Therefore, this deliverable proposes the Virtual Network layer architecture and evaluates a set of Management- and Control Planes that can be used for the partitioning and virtualization of the FEDERICA network resources. This evaluation has been performed taking into account an initial set of FEDERICA requirements; a possible extension of the selected tools will be evaluated in future deliverables. The studies described in this deliverable define the virtual architecture of the FEDERICA infrastructure. During this activity, the need has been recognised to establish a new set of basic definitions (taxonomy) for the building blocks that compose the so-called slice, i.e. the virtual network instantiation (which is virtual with regard to the abstracted view made of the building blocks of the FEDERICA infrastructure) and its architectural plane representation. These definitions will be established as a common nomenclature for the FEDERICA project. Other important aspects when defining a new architecture are the user requirements. It is crucial that the resulting architecture fits the demands that users may have. Since this deliverable has been produced at the same time as the contact process with users, made by the project activities related to the Use Case definitions, JRA1 has proposed a set of basic Use Cases to be considered as starting point for its internal studies. When researchers want to experiment with their developments, they need not only network resources on their slices, but also a slice of the processing resources. These processing slice resources are understood as virtual machine instances that users can use to make them behave as software routers or end nodes, on which to download the software protocols or applications they have produced and want to assess in a realistic environment. Hence, this deliverable also studies the APIs of several virtual machine management software products in order to identify which best suits FEDERICA’s needs.Postprint (published version

FROM THE BACK OFFICE TO THE FRONT LINES OSS: Potential Land Mines on the Front Lines

The Telecommunications Act of 1996 struck a bargain that allowed Bell Atlantic and the other Regional Bell Operating Companies ( RBOCs ) to gain entry into the long distance business by opening their monopoly local exchange markets to meaningful competition. A key aspect of the market-opening process is that the RBOCs, as well as generally all Incumbent Local Exchange Carriers ( ILECs ) are required to provide new Competitive Local Exchange Carriers ( CLECs ) access to the Operations Support Systems ( OSS ). The incumbents use OSS to serve their customers at quality levels equal to what the incumbent provides to itself

The impact of implementation of VOIP in call centres : A Western Australia perspective

By fostering the finalization of open standards and the convergence of voice, video and data, the internet protocol provides an ideal driver for the definition of the infrastructure of new multimedia and advanced communications applications (Adams & Bhalla, 2005). The key advantages of Voice over Internet Protocol (VoiP) for enterprises have been the promise of lower costs, infrastructure consolidation and increased flexibility. Carriers are also positioning VoiP as a cost-saving business solution. It is an application which seemed like a godsend to business and people alike who rely on telephony services (Blood, 2005). The aim of this study was to investigate what factors may influence the adoption of VoiP as a technology as a West Australia context. Specifically the research undertook a case study using an establish call centre in a government agency, City of Melville. The company is a provider of wide range of services including recreation centres, aquatic centres, libraries, creches, pre-school centres, community centres, food inspection services, citizenships, recycling, planning and building services, maintenance, streetscapes, landscaping disability services, immunisation clinics, cultural and educational centres, environmental preservation and management. This study analysed the steps through to adoption of VoiP and IP telephony from the original technology for the Melville City Council call centre. Also, the procedures towards acquisition and installation of the supporting framework that eases the implementation and day to day running are depicted. The main impacts on the company as a result of the implementation in terms of cost reduction and implications, staff satisfaction and benefits, ease of business operations has been reported in this study. Statistics of the business functions and operations based on VoiP solutions were critically analyzed. Results from the research suggested further research needs to be undertaken on factor affecting the adoption of VoiP in a Western Australia context

Supply Chain (micro)TMS development

Project Work presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementThe rise of technology across many verticals has necessitated the company’s move to digitalization. Despite “XPTO” company a well know player on the retail and success on e‐commerce internal market, they aimed at the strategy of continuous innovation to drive business growth and strengthen their position as a premium brand. They decided to move forward into digitalism inside cloud based solutions to get all the advantages of microservices architecture: optimize logistics and supply chain management, speed up the workflow and maximize service efficiency. An agile organization is not achieved purely by shifting the focus from traditional functional/ technological oriented organizations. The new way to organize teams must reflect all the principles and right segregations of roles, which will be the most immediate and visible disruption and cutover from the traditional way of managing the IT. In this project we aim to use agile framework with development based in house cloud microservice solution for a (micro)TMS solution/system that address the immediate needs imposed by the market in order to use it has competitive advantage

Applications of satellite technology to broadband ISDN networks

Two satellite architectures for delivering broadband integrated services digital network (B-ISDN) service are evaluated. The first is assumed integral to an existing terrestrial network, and provides complementary services such as interconnects to remote nodes as well as high-rate multicast and broadcast service. The interconnects are at a 155 Mbs rate and are shown as being met with a nonregenerative multibeam satellite having 10-1.5 degree spots. The second satellite architecture focuses on providing private B-ISDN networks as well as acting as a gateway to the public network. This is conceived as being provided by a regenerative multibeam satellite with on-board ATM (asynchronous transfer mode) processing payload. With up to 800 Mbs offered, higher satellite EIRP is required. This is accomplished with 12-0.4 degree hopping beams, covering a total of 110 dwell positions. It is estimated the space segment capital cost for architecture one would be about $190M whereas the second architecture would be about$250M. The net user cost is given for a variety of scenarios, but the cost for 155 Mbs services is shown to be about $15-22/minute for 25 percent system utilization
