An Edge and Fog Computing Platform for Effective Deployment of 360 Video Applications
This paper has been presented at: Seventh International Workshop on Cloud Technologies and Energy Efficiency in Mobile Communication Networks (CLEEN 2019). How cloudy and green will mobile network and
services be? 15 April 2019 - Marrakech, MoroccoIn press / En prensaImmersive video applications based on 360 video
streaming require high-bandwidth, high-reliability and lowlatency
5G connectivity but also flexible, low-latency and costeffective
computing deployment. This paper proposes a novel
solution for decomposing and distributing the end-to-end 360
video streaming service across three computing tiers, namely
cloud, edge and constrained fog, in order of proximity to the
end user client. The streaming service is aided with an adaptive
viewport technique. The proposed solution is based on the H2020
5G-CORAL system architecture using micro-services-based design
and a unified orchestration and control across all three tiers
based on Fog05. Performance evaluation of the proposed solution
shows noticeable reduction in bandwidth consumption, energy
consumption, and deployment costs, as compared to a solution
where the streaming service is all delivered out of one computing
location such as the Cloud.This work has been partially funded by the H2020 collaborative Europe/Taiwan research project 5G-CORAL (grant num. 761586)
A Multi-Site NFV Testbed for Experimentation With SUAV-Based 5G Vertical Services
[EN] With the advent of 5G technologies, vertical markets have been placed at the forefront,
as fundamental drivers and adopters of technical developments and new business models. Small Unmanned
Aerial Vehicles (SUAVs) are gaining traction in multiple vertical sectors, as key assets to generate, process,
and distribute relevant information for the provision of value-added services. However, the enormous
potential of SUAVs to support a exible, rapid, and cost-effective deployment of vertical applications is
still to be exploited. In this paper, we leverage our prior work on Network Functions Virtualization (NFV)
and SUAVs to design and build a multi-site experimentation testbed based on open-source technologies.
The goal of this testbed is to explore synergies among NFV, SUAVs, and vertical services, following a
practical approach primarily governed by experimentation. To verify our testbed design, we realized a
reference use case where a number of SUAVs, cloud infrastructures, and communication protocols are used to
provide a multi-site vertical service. Our experimentation results suggest the potential of NFV and SUAVs
to exibly support vertical services. The lessons learned have served to identify missing elements in our
NFV platform, as well as challenging aspects for potential improvement. These include the development of
speci c mechanisms to limit processing load and delays of service deployment operations.This work was supported in part by the European Commission under the European Union's Horizon 2020 program (5GRANGE Project, grant agreement number 777137), and in part by the 5GCity Project funded by the Spanish Ministry of Economy and Competitiveness under Grant TEC2016-76795-C6-1R, Grant TEC2016-76795-C6-3R, and Grant TEC2016-76795-C6-5R
