Programmability, control and flexibility can be considered as some of the indirect enablers for the success of 5G technologies. A key driver towards this are mechanisms or methodologies to drive shorter time to market for suppliers and operators of virtual network functions (VNFs) and network services. 5GTANGO includes a DevOps approach that can be utilized for the validation and verification (V&V) of VNFs and network services. In this paper, we elaborate further on the approaches made in the areas of testing, catalogues and package management as a means to enable that full DevOps V&V workflow. Finally, we explore the deployment requirement of the V&V via one of our pilot use cases

Inter-Vehicle Communication will play an important role in upcoming Intelligent Transportation Systems (ITS). Vehicles are equipped with communication units, able to offer and share information with other cars, infrastructure components or cloud servers. In recent years, researchers in academia and industry worked towards ITS standards to tackle the challenges set by connected vehicle environments such as high latency or communication failures. However, the host-centric communication model of today’s networks complicates the exchange of information, especially in vehicle-to-infrastructure (V2I) and vehicle-to-cloud (V2C) communication. The Information-Centric Networking (ICN) paradigm is a promising candidate to solve the challenges set by connected vehicles. Addressing data by name instead of the location, and the resulting capabilities such as in-network caching, make it a good fit for scenarios which are characterized by a high degree of mobility. In this paper, we propose an architectural concept in which ICN and the inter-vehicle communication system ETSI ITS-G5 (based on IEEE 802.11p) coexist and complement each other. Based on the OpenC2X open source platform, we introduce a prototype implementation and evaluate the prototype within a real world testbed.



11:36 – MONICA in Hamburg: Towards Large-Scale IoT Deployments in a Smart City

Modern cities and metropolitan areas all over the world face new management challenges in the 21st century primarily due to increasing demands on living standards by the urban population. These challenges range from climate change, pollution, transportation, and citizen engagement, to urban planning, and security threats. The primary goal of a Smart City is to counteract these problems and mitigate their effects by means of modern ICT to enhance the administration and infrastructure of a city. Key ideas are to utilise network communication to inter-connect public authorities; but also to deploy and integrate numerous sensors and actuators throughout the city infrastructure — such is also widely know as the Internet of Things (IoT). Thus, IoT technologies will be an integral part and key enabler to achieve many objectives of the Smart City vision. The contributions of this paper are as follows. We first give an overview of IoT platforms, technologies and network standards that can help to foster a Smart City environment. Second, we introduce the EU project MONICA which aims for demonstration of large-scale IoT deployments at public, inner-city events and give an overview on its IoT platform architecture. And third, we provide a case-study report on SmartCity activities by the City of Hamburg and provide insights on recent (on-going) field tests of a vertically integrated, end-to-end IoT sensor application.



11:54 – Integrating Research Testbeds into Social Coding Platforms

The adoption of social coding platforms among software developers is particularly high because it increases collaboration and productivity as well as code re-use. On the other hand research testbeds do not generally have such high adoption rate. The learning curve of adopting new technology represents an initial drop in performance before it increases. However this effect is unexpected by many users and there is a risk that they will abandon new technology before their performance increases. The main contribution of this paper is to introduce methodology to take advantage of the high adoption rate of social coding platforms to improve the adoption of research testbeds. The proposed approach is that a social coding platform serves as a common gateway to various testbeds since it is something many developers are comfortable with and thus the initial effort needed to start using the testbed is decreased and the probability that experimenters continue to use a testbed is higher.



12:12 – Dev-for-Operations and Multi-sided Platform for Next Generation Platform as a Service

This paper presents two specific aspects of the Telco ecosystem transformation in the era of cloud-native microservice-based architectures. Development-for-Operations (Dev-for-Ops) impacts not only the overall workflow for deploying Platform as a Service (PaaS) in an open foundry environment, but also the Telco business as well as operational models to achieve economy of scope and economy of scale. For that purpose, we construct an integrative platform business model in the form of a Multi-Sided Platform (MSP), which is ruled by service providers, for building Telco PaaSes.
