At Mobile World Congress, we hosted a joint demo with BT showcasing end-to-end, multi-layer transport network slicing and assurance. The demo illustrated how edge computing and network slicing techniques can enable emerging 5G applications. These include use cases that require ultra-reliable low-latency communications (uRLLC), such as autonomous vehicle control. Check out the accompanying slide deck.
