Enterprise digital transformation is maturing at an alarming rate, driving the construction of ICT infrastructure, which ushers in a new era of rapid growth. Data and algorithms are now being used to replace the decision making usually facilitated by people. As the scale and complexity of networks are increasing exponentially, network changes have exceeded the limits of manual processing. In response, Huawei has launched the industry-leading L3 ADN solution. This solution redefines intelligent O&M of enterprise data center and campus networks through innovative features, such as intent-driven deployment, change simulation and verification, "1-3-5" troubleshooting, and terminal auto-adaptation. The solution paves the way towards the L3 ADN phase featuring a conditional autonomous network, effectively accelerating the digital transformation of industries.
