Ecosystems and co-creation

Test network itself is already an innovation ecosystem and aims to bepart of bigger co-creation environment combining different applicationdomains and their actors

Basic Concepts (cont.)

Open & Closed Innovation and application development platformsIn practise a server platform providing tools e.g. for applicationdevelopment (APIs), software development kits (SDKs) etc.Platforms and methods can be ”open” or ”closed”Open Innovation is a paradigm assuming that firms can e.g.crowdsource creation and development of ideas by e.g. openingspecific system APIs without direct or strict controlClosed Innovation is paradigm assuming the IPR ownership andcreation and management of ideas is strictly controlled by companyproviding the APIs and SDKsThe 5G Test Network can host the platform for e.g. some specificSDKs and APIs provided by companies

Smart city

Industrial applications

Possibilities to integrate the network with 3rd party cloud systemsIoT: Microsoft Azure, Thingworx, Amazon web servicesPrivate clouds

Possibilities to connect also to other external services and networksVPN tunneling from remote sites to servicesIn future also remote LTE/LTE-M/5G RANs could be connected

Application and Service Interfaces and Tools

Applications and test scenarios will define what kind of tools are requiredThe test network environment provides the generic servicesSupport for open source SQL databases such as

MySQL, MariaDB and PostgreSQLIoT application and transport protocols at the moment, the protocol supportis not limited to these

CoAP (UDP), MQTT (TCP), Websockets (TCP), REST (HTTP)Most of the opensource programming environments and languages arenatively supported

For example for web development PHP, Perl etc.Operating system support mainly for Linux and other open source operatingsystems

Using commercial, licenced operating systems in service core needs to benegotiated if the use is required for application development or services.

Extending cloud infrastructure towards edge ofthe network

The main targets for distributed cloud solutions are toimprove system performance,minimize delays in data processing and service/data accessimprove energy-efficiency of the systems andenable 3rd party application development for ”in-network” servicesespecially for content distribution, IoT and Tactile Internet applications

Virtualisation and software defined networking are the mainenablers also for distributed edge cloud solutions

Extending cloud infrastructure towards edge ofthe network (cont.)

Several almost similar approaches to distribute computing and extendcloud infrastructure in network have been considered

Mobile Edge Computing: ETSI workgroup for standardizing APIsand defining architecture for cloud and virtualization platformespecially for mobile networksFog Computing: Cisco defined solution for distributed, multi-layercloud infrastructureCloudlets: Extension for OpenStack to support near-realtime/just-in-time application and service provisioning in edge nodesMicro datacentre: Microsoft proposal for extending hyperscalecloud data centres (Azure) to support low-latency and energy-efficient processing

Industrial applications

Cloud server for collecting sensor data: websocket, http,coap, mqtt etc. can be supportedAnalysing software also in core network IaaS cloudAnalysis and application can be also in external service. Insuch a case the connectivity needs to arranges through VPNif data is collected through 5GTN network.

Dynamic and scalable next-generation CDNIntelligent load-balancing and resource-aware solutions for content delivery networks (CDN)

Utilise network virtualization and enhanced CDN management.Allows scaling of CDN architecture and performs dynamic load-balancing based on contentrequests from the end users

ScenarioAdd and/or remove virtualized CDN edge servers and reroute CDN users based on theresource needs (or location) to achieve more balanced traffic load in the CDNIntroduce virtual edge server(s) as close as possible to the end-user (e.g. close to the basestation – MEC/Fog/Cloudlet technologies)
