Modern applications, from critical Internet of Things (IoT) systems to real time multimedia communications, require low and stable latencies in order to be useful. 5G will bring more bandwidth at very low latencies which will enable new use cases and enhance the performance of applications which are currently used over 4G.

Apart from the air segment where 5G brings a significative improvement, the Network Functions Virtualization (NFV) architectures associated to running the services must be able to warrant that latency values are contained within a range of tolerable values. 5GTANGO puts special focus on innovative strategies to deal with the different network requirements of a wide range of applications from the Sonata NFV Service Platform. This means that the operator will not only be able to use different quality of service (QoS) defined by 5QI values from the device to the 5G Core, but also in the NFV platform.

The necessity to monitor Network Services in the 5G ecosystem


In the next years, 5G infrastructure will become a ubiquitous, flexible and programmable network that will be in the core of every social, business and cultural process, enabling both economic growth and social prosperity. However, the 5G vision poses significant technical challenges that must be fulfilled, including the concept of agile programmability and supporting the introduction of management mechanisms for the efficient instantiation of innovative services across heterogeneous network components, virtualized infrastructures and geographically dispersed cloud environments.

As factories become mobile, machines will physically move inside a factory or to another site. Current network infrastructure does not match the associated requirements because wired connections and fix subnets as well as fix routes cause high effort for each adaptation. Using NFV technology and the 5GTANGO platform, the factory network will be raised to a new level of flexibility.


The smart manufacturing pilot focuses on three use cases for modern factories: create an innovative, flexible factory network and analyze the operational data, machine data, and process data (O/M/P data) gathered from the machines; detecting and containing threats; and enable augmented reality (AR-)based support for machine maintenance and repairs.


The following use cases were defined during a face-2-face meeting at Weidmüller premises in Detmold. The participants gained many insights of a manufacturing process by visiting one of Weidmüller’s factories and created a time schedule for the development of needed components. Many aspects of the use cases will be tested and evaluated in demonstration setups during the final year of 5GTANGO.

A key objective of 5G and Software Defined Networking (SDN) technologies is the provision of Quality of Service (QoS) guarantees. These guarantees are reflected to the requirements emerging from the agreements between the customers and service providers, the corresponding Service Level Agreements (SLAs). While traditional SLAs included aspects for example regarding data center availability of "five 9s", or five minutes of downtime per year [1], a 5G-driven SLA includes additional aspects related both to the infrastructure and to the provisioned services, as for example: “five 9s availability” while also “2 seconds to deploy a new Service Instance”.
But what is an SLA? An SLA is a contract between the Network Service (NS) provider and the customer, which underlines each party’s responsibilities while at the same time defining the performance standards that are to be met by the provider [2]. SLAs establish customer expectations regarding the service provider's performance and overall quality. Over the past few years, SLAs set the expectations for a service provider performance, establish penalties for missing the targets and, in some cases, bonuses for exceeding them. In that concept, SDN explosion could not leave unaffected the evolution of SLA models, and their flexibility in adapting more demanded parameters. 5GTANGO is a frontrunner in defining SLAs for 5G environments, by introducing a complete SLA Management Framework, in order to fulfill the gap between NS providers and their customers [3].

In this blog post, we describe the integrated workflow with 5GTANGO's SDK from setting up a workspace to on-boarding a complete package with a desired network service. The SDK supports developers in all these steps through multiple tools that work together seamlessly and are available on public GitHub repositories.
