Deutsche Telekom and Huawei demonstrated autonomous, real-time, dynamic end-to-end slicing of a 5G Radio Access network (RAN), data center facilities and the interconnecting transmission network.
The demo, which was conducted in Deutsche Telekom’s 5G:haus lab in Bonn, Germany, showed how different network slices can be created automatically in an optimized way on a shared RAN, Core and transport network. This allows slices creation in sub-minute time while ensuring an efficient and intelligent allocation and re-allocation of resources as required for each individual slice.
DT said the bandwidth-based transport network slicing utilized TSDN controllers and the underlying DWDM nodes. The tests validated real-time dynamic adjustments of network slices on very fine spectral granularity, signal process and protocol stack.
F-OFDM air interface technology providess the spectral granularity and also permits efficient co-existence and isolation of all 5G New Radio (5G NR) slices. The end-to-end network slicing automation was based on Service Oriented Network Auto Creation (SONAC), which uses software-defined topology (SDT), software defined protocol (SDP) and software-defined resource allocation (SDRA) to ensure the automatic implementation of slice management, service deployment, resource scheduling, and fault recovery based strictly on a detailed and thorough network data analysis.
“Network Slicing is envisaged for 5G to provide differentiated connectivity quickly and efficiently for the diverse future applications that our customers will demand. With automated network slicing, the development of highly flexible end-to-end network slicing becomes more complete,” said Bruno Jacobfeuerborn, Chief Technology Officer, Deutsche Telekom.
“Huawei has made significant key 5G technologies. This additional breakthrough on E2E network slicing automation is a great contribution to the 5G industry of the future and helps to bring the vision of 5G slicing closer to reality for our customers,”said Dr. Wen Tong, Huawei Fellow, CTO, Huawei Wireless.
