Deutsche Telekom and Ericsson demonstrated 5G end-to-end network slicing for latency-critical enterprise applications with guaranteed Quality of Service.
The 5G slicing trial includes SD-WAN and end-to-end service orchestration afor latency-critical applications in different countries. This approach will be especially beneficial for global enterprises who run latency-critical applications in different international subsidiaries.
In this trial, the QoS connectivity was extended from Germany to Poland using a 5G slicing setup that is based on commercial grade Ericsson 5G Standalone (SA) radio and core network infrastructure and a Deutsche Telekom commercial SD-WAN solution. The home operator-controlled User Plane Function (UPF) is placed in Poland as the visited country and the entire setup is managed by an Ericsson orchestrator integrated with a Deutsche Telekom business support system via open TM Forum APIs. Combining 5G slicing and SD-WAN technology allows flexible connectivity establishment and control, while traffic breakout close to the application server in visited countries enables low latency.
Deutsche Telekom said the trial also verified the radio resource partitioning (RRP) for enhanced RAN slicing. The trial achieved an efficient isolation and sharing of radio resources among network slices by isolating the radio resources into partitions that can be associated per network slice in a dynamic way. Each network slice can rely on the availability of a certain minimum allocation of radio resources, while unused capacity is dynamically made available to other network slices, thus maximizing the overall capacity of the system. For an operator, this enables delivery of high-value services with SLA assurance, while at the same time using valuable spectrum efficiently.
Alex Choi, SVP Technology Strategy & Innovation, Deutsche Telekom, says: “Network slicing is a key 5G enabler to deliver tailored connectivity services to enterprise customers. By flexibly combining 5G slicing with SD-WAN in an international setup, we can address the emerging need among enterprises for uniform global connectivity with guaranteed quality of service.”
Erik Ekudden, Senior Vice President, CTO and Head of Group Function Technology, Ericsson says: “Combining different technologies in an intelligent and flexible way across borders to address the emerging needs of globally operating enterprises is another proof point of the promise that a global 5G ecosystem can offer.”
