SDN Controller Mechanisms for Flexible and Customized Networking

Software-Defined Networking (SDN) is seen as the most promising networking technology today. The spread of a new technology depends on the acceptance of the engineers implementing the networks. Typically, when engineers start the conceptualization of new network devices that work with a new paradigm, and that should provide expected business values, they must identify and utilize technical enablers for the defined business use cases. This paper tries to summarize essential SDN applications and defines the technical enablers for advanced and efficient SDN networking. To this end, we identify the core technical mechanisms, expecting to provide a useful analysis for the design of new SDN networks

IPv6 in Wireless Networks – Selected Issues, Journal of Telecommunications and Information Technology, 2011, nr 2

The article presents issues concerning the construction of autonomous wireless networks based on the IPv6 protocol. Prospects of implementation of IPv6 in wireless networks and IPv6 features and mechanisms important in such applications are discussed. Research directions related to the use of IPv6 in wireless networks are also outlined. Then the selected concepts are described, arising in the course of the EFIPSANS (Exposing the Features in IP Version Six Protocols that can be Exploited/Extended for the Purposes of Designing/Building Autonomic Networks and Services) project, during studies on the autonomy of nodes and routing configuration for wireless networks. Concepts presented here apply to wireless ad hoc mesh networks. Discussed is their nature and aspects related to auto-configuration and autonomously operating routing. In particular, there is a Wireless Autonomic Routing Framework (WARF) architecture presented

UAV Support for Mission Critical Services

International audienceMission critical solutions are essential for providing communications and services in the case of the troubles with connectivity that are often found in infrastructure-based solutions. Such solutions are typically used in the case of disasters, lack of energy, etc. There exist several narrowband solutions that provide countrywide coverage in certain countries. In recent years, the activities related to creating mission-critical broadband solutions based on Long Term Evolution (LTE) have led to the definition of LTE Mission Critical (LTE-MC). Both solutions ignore virtualization and require dedicated mobile terminals as a part of the mission-critical communication solution. This paper describes the opportunities, open issues and a proposal of a solution that exploits Unmanned Aerial Vehicles (UAVs) and network virtualization for mission-critical services. The presented approach combines Cloud/Edge and Fog orchestration to efficiently use all the available resources, including virtualized resources of the end-user devices

Mobile Networks’ Support for Large-Scale UAV Services

The services based on Unmanned Aerial Vehicles (UAVs) have started to be used in many countries but not on a large scale yet. The paper describes the present status of UAV services and a concept of a solution for large-scale deployment of safe and reliable UAV services that use the 5G network for communication with UAVs. Based on the Standards Developing Organizations and related industry fora activities, unmanned traffic and airspace regulations, especially the commonly supported concept of Unmanned Aircraft Systems Traffic Management (UTM), UAV-related communication requirements and 5G System (5GS) features, we have developed an alternative approach to the integration of UAV and 5GS. The proposed concept includes a set of enablers that can be provided by Mobile Network Operators in order to not only support but also leverage UAV services. As work on many items is still in progress, we identify a list of open issues and challenges and present them at the end of the paper with the main focus on the MNO–UTM provider relationship and safe flights

High Mobility 5G Services for Vertical Industries – Network Operator’s View

Part 1: 6th Workshop on “5G – Putting Intelligence to the Network Edge” (5G-PINE 2021)International audienceThe 5G System (5GS) is regarded as a multi-faceted, universal communication platform that could address the increasingly stringent requirements of both modern industries and network end users. Several proposed mechanisms, such as network slicing or its control exposure, aimed to facilitate access to the network for the external stakeholders, enable the creation of one common ecosystem that could be exploited according to the specific service needs. With the recent advancements in the automotive and aviation sectors, the significant increase of interest regarding the current state of preparedness of the 5GS and its capabilities to support those services is observed. The paper presents the analysis of the 5G technology readiness in the context of high mobility vehicular scenarios, including automotive and unmanned aviation use cases. The significant features and key gaps and challenges have been outlined with the emphasis on the dynamics of business processes and interactions between automotive, aviation and 5G ecosystems

A Novel Architectural Approach for the Provision of Scalable and Automated Network Slice Management, in 5G and Beyond

Part 1: 6th Workshop on “5G – Putting Intelligence to the Network Edge” (5G-PINE 2021)International audienceThe paper discusses a novel architecture proposed within the scope of the ongoing MonB5G EU-funded project. Considering a multiplicity of challenges towards realizing an effective network slice management in modern 5G networks, our work considers explicitly the context promoted by the Zero-touch network and Service Management (ZSM) framework, assessed as an indispensable part of next-generation management systems. MonB5G focuses upon the provision of scalable and automated management and orchestration of high numbers of parallel network slices, as envisioned in 5G and beyond. Within this scope, we propose a detailed architecture composed of static and dynamically deployed components. Altogether, they support operations related to slicing orchestration, fault management (self-healing), self-configuration, performance optimization (including energy saving), and security-related operations of slices. In the paper, we identified each separate architectural layer and explained all involved modules and interfaces. The proposed framework is able to support the deployment of a massive number of slices in different administrative and technological domains. Furthermore, the potential extensions and/or enhancements of the architecture are also proposed and assessed
