The virtualized network construction needs the automatic solution
The global telecom network is gradually evolving towards virtualization. However, the decoupling degree of software from hardware increases after virtualization, and the networking becomes more complicated. The network architecture is evolving towards multiple manufacturers, multiple platforms, multiple components, and multiple interfaces. Operators are facing many challenges during virtualization network construction, such as integration of multiple vendors across the domain. End-to-end and automatic tool solutions are urgently required to reduce the integration difficulty, solidify the integration process and improve integration efficiency.
Recently, ZTE officially released the NFV AIC (Auto Integration Center) platform, which can fully meet the requirements of operators. The AIC, through integrating and solidifying the NFV integration process, implements the automation of planning and design, network deployment, and acceptance tests of core network virtualization through tools, significantly shortening the network construction time. In addition, the AIC implements the "zero distance" between functions and customer requirements in the full lifecycle of NFV integration server through a friendly user interface, effectively solving the pain points of operators in the integration of virtualized networks.
The AIC is used to achieve innovations of the virtualized network construction mode
The AIC provides end-to-end and one-stop tools for virtualized core network construction, including planning and design, solution verification, network deployment, and integration test. Through the tool, NFVI integration, MANO integration, VNF integration, and other integration scenarios can be implemented automatically. This greatly reduces the integration difficulty of network construction, improves efficiency, guarantees quality, reduces integration costs, accelerates NFV network construction, and helps customers achieve rapid network transformation.
By using the AIC, operators can automatically complete the planning, deployment, and testing of virtualized networks, greatly improving the integration efficiency and quality of NFV networks. The AIC really achieves the innovation of the NFV integration mode.
Description of the AIC architecture and functions
The overall architecture of the AIC is displayed as follows:

NFV project assets management implements unified management of unified assets
The AIC tool platform supports unified access and management of NFV projects. The platform integrates project asset management, makes experience accumulation, and implements information management and release through the project library, template library, case library, version library, and experience library functions. The AIC tool platform solves the problem that traditional projects cannot effectively integrate design documents or test cases, and cannot be duplicated.
Applications of the virtualized AIC in the NFV network construction
At present, the AIC has been successfully applied in many NFV commercial networks and pilot offices, and has been highly praised by customers.
Tianjin Unicom used the AIC to implement the integration and rapid deployment of the 5GC pilot office, and won the 2018 Best Practice Award in the SDN&NFV field of the media ICT industry. In addition, the AIC tool also participates in China Mobile's OPEN-AUTO cooperation plan. It is collaborating with operators in R&D and verification of integrated automation tools to build a partner-like industrial ecosystem, create a new mode
