Ericsson, VMware, and AT&T Join Forces


In March 2021, Ericsson, VMware, and AT&T joined forces to combine Software-defined Wide Area Network (SD-WAN) and 5G with network slicing to demonstrate an enterprise grade real-time use-case. The successful proof of concept (PoC) utilized AT&T’s physical 5G network, VMware’s virtualized SD-WAN, and Ericsson’s dynamic orchestration platform, whilst applying a powerful hosted cloud gateway to enable direct cloud access and an easily scalable network architecture for a cashier-less automated checkout and smart workload placement system. The customer focused use case highlighted that 5G with network slicing could have cross-enterprise vertical applicability, especially for verticals with real-time interactions with customers that require access to applications across independent, optimized, secure, and smart network connections.

The PoC featured multiple Internet of Things (IoT) endpoints that ran on one physical 5G network. Network slicing on this physical architecture meant that each IoT device was provided with a sperate ‘slice’ which…
