SK Telecom and Ericsson demonstrated Software-Defined Telecommunications Infrastructure (SDTI) based on Hyperscale Datacenter System 8000 at 5G Playground, the company’s 5G technology innovation center located in Bundang, Korea.
Ulf Ewaldsson, CTO of Ericsson, said: “We are pleased to jointly develop this SDTI technology based on Ericsson HDS 8000. Ericsson will continue to lead the 5G network technical innovation toward the 5G commercialization in collaboration with SK Telecom.”
SDTI refers to an infrastructure platform where all mobile network infrastructure components, such as CPU, memory and storage, are disaggregated as customizable modules that can be dynamically recomposed together to provide the optimal level of infrastructure scale for various 5G services based on their requirements, said SK Telecom in a statement.
Based on the concept of infrastructure slicing, SDTI allows for the dynamic composition and lifecycle management of infrastructure at the physical hardware layer, ranging from ultra-mini servers for personalized services such as individual broadcasting and personal blogs to massive scale servers for services such as mobile telecommunications and OTT services.
SDTI enhances efficiency in network infrastructure upgrades as the disaggregated module of the server can be separately upgraded. It also offers strengthened security by physically separating each user’s infrastructure.
SK Telecom expects that, as there are active discussions on virtualized infrastructure platform for 5G by international organizations such as Open Compute Project (OCP) and Telco Infra Project (TIP), the world’s first demonstration of SDTI is expected to draw a lot of attention from both industry and standardization communities.
SK Telecom and Ericsson plan to jointly build end-to-end 5G pilot system – which consists of 5G device, radio, core network, and SDTI – by the end of 2016, and verify the technical feasibility and performance of the 5G system.
“SDTI is an innovative technology that enhances network efficiency by flexibly constructing hardware components to satisfy the infrastructure performance requirements of diverse 5G services,” said Park Jin-hyo, head of Network Technology R&D Center of SK Telecom.
