Design and validation of a multi-service 5G network with QoE-aware orchestration

Proceeding of: WiNTECH '18: 12th International Workshop on Wireless Network Testbeds, Experimental Evaluation & CharacterizationWhile the work on architectural and algorithmic solutions for 5G has reached a good maturity level, the experimental work lags behind, in particular on the development of open source solutions. In this paper, we describe our implementation experiences when deploying a small-scale multi-service network prototype, used to demonstrate some selected advanced features of 5G Networking. We describe our implementation experiences supporting two heterogeneous services over two independent slices, namely, video streaming and augmented reality, showcasing key features such as multi-slice orchestration, RAN slicing and support for local breakout. While the applications running the services rely on proprietary code, the core of our implementation is completely open-source.This work was supported by the H2020 5G-MoNArch project (grant agreement no. 761445), by the Spanish Ministry of Economy and Competitiveness through the 5G-City project (TEC2016-76795-C6-3-R) and by the Madrid Regional Government through the TIGRE5-CM Program under Grant S2013/ICE-2919

A future-proof architecture for management and orchestration of multi-domain NextGen networks

The novel network slicing paradigm represents an effective turning point to operate future wireless networks. Available networking and computational resources may be shared across different (instantiations of) services tailored onto specific vertical needs, envisioned as the main infrastructure tenants. While such customization enables meeting advanced Key Performance Indicators (KPIs) introduced by upcoming 5G networks, advanced multi-tenancy approaches help to abate the cost of deploying and operating the network. However, the network slicing implementation requires a number of non-trivial practical considerations, including e.g. (i) how resource sharing operations are actually implemented, (ii) how involved parties establish the corresponding agreement to instantiate, operate and terminate such a sharing or, (iii) the design of functional modules and interfaces supporting these operations. In this paper, we present a novel framework that unveils proper answers to the above design challenges. While existing initiatives are typically limited to single-domain and single-owner scenarios, our framework overcomes these limitations by enlarging the administrative scope of the network deployments fostering different providers to collaborate so as to facilitate a larger set of resources even spread across multiple domains. Numerical evaluations confirm the effectiveness and efficiency of the presented solution.This work was supported in part by the 5G-MoNArch Project, in part by the Phase II of the 5th Generation Public Private Partnership (5G-PPP) Program, in part by the European Commission within the Horizon 2020 Framework Program under Grant 761445, in part by the 5G-MoNArch Project builds on the results of the 5G-PPP Phase I Project 5G-NORMA, and in part by the European Union Horizon 2020 Project 5G-CARMEN under Grant 825012.

Experimenting with open source tools to deploy a multi-service and multi-slice mobile network

With network slicing, the infrastructure is divided into separate networks, each one customized to provide a specific service. Network slicing is a key technology to efficiently support services with very diverse requirements, such as the ones that should support 5G networks. While the architectural work for 5G is well advanced, and many theoretical solutions that address diverse aspects such as resource assignment or service composition exist, the experimental work lags behind. In this paper, we aim at filling this gap by describing our implementation experiences when deploying a small-scale multi-service prototype. We consider a video streaming service and an augmented reality service, each one provided over a different network slice, and extend existing open-source software solutions for a better provision of them. Our implementation showcases key features of future 5G networks, such as radio slicing with service differentiation, support for local breakout, or multi-slice orchestration with QoE-triggered optimization. With the core of our implementation being open-source, we believe that our results will prove very useful to researchers and practitioners working on this area of research.This work was supported by the H2020 5G-MoNArch (grant agree-ment no. 761445), 5G EVE (grant agreement No. 815074) and 5G-Tours (grant agreement No. 856950) Project
