“The global telecommunications network is gradually evolving towards virtualization. However, as the degree of decoupling of software and hardware increases after virtualization, the networking becomes more complex. The network structure is evolving towards multi-vendor, multi-platform, multi-component, and multi-interface. Businesses will face multiple challenges such as multi-vendor and cross-domain integration when building virtualized networks, and urgently need end-to-end, automated tool solutions to reduce integration difficulty, solidify the integration process, and improve integration efficiency.
Virtualized network construction requires automation solutions
The global telecommunications network is gradually evolving towards virtualization. However, as the degree of decoupling of software and hardware increases after virtualization, the networking becomes more complex. The network structure is evolving towards multi-vendor, multi-platform, multi-component, and multi-interface. Businesses will face multiple challenges such as multi-vendor and cross-domain integration when building virtualized networks, and urgently need end-to-end, automated tool solutions to reduce integration difficulty, solidify the integration process, and improve integration efficiency.
A few days ago, ZTE officially released the NFV AIC (Auto Integration Center) automated integration tool platform, which can fully meet the needs of operators. The AIC tool platform integrates and solidifies the NFV integration process, realizes the planning and design of core network virtualization construction, network deployment and automation of acceptance testing through tools, greatly shortens the network construction time, and integrates the whole life of the network through a friendly user interface. Realize the “zero distance” between tool functions and customer needs in the cycle, effectively solving the pain points of operators in virtualized network integration.
Automation Integration Tool AIC Platform Realizes the Innovation of Virtualized Network Construction Model
The AIC tool platform can provide end-to-end, one-stop tool support for virtualized core network construction from planning and design, solution verification, network deployment, to integration testing. In this integration scenario, work is automatically completed, which greatly reduces the integration difficulty of network construction, improves efficiency, ensures quality, reduces integration costs, accelerates operator NFV network construction, and helps customers achieve rapid network transformation.
l Automatic output of NFV network integration design, improve integration design efficiency, automatic generation of integrated LLD, shorten integration design time, and reduce the workload of traditional deployment from weeks to one day;
l NFV network integration deployment can be completed automatically with one click, which reduces the difficulty of on-site deployment and improves deployment efficiency by dozens of times (single-DC deployment can be achieved within one day);
l Automatic realization of NFV network integration test, more than 5,000 test cases, automatic generation of test plans according to customer requirements, automatic execution of tests and output of results.
Through the application of AIC tools, operators can automatically complete virtualized network planning, deployment, and testing, greatly improving the efficiency and quality of NFV network integration, truly achieving simplicity over complexity, and realizing the innovation of NFV integration mode.
AIC Integrated Automation Tool Platform Architecture and Functional Description
The overall architecture of the AIC tool platform is as follows:
Figure 1: Integrated AIC Tool Platform Architecture
The AIC tool platform consists of three business modules and a support platform:
♦ Design tool (iDevise): Summarize configuration parameters and resource requirements for hardware, cloud platform, MANO and VNF deployment through GUI interface, and automatically generate integrated scene component instantiation parameter files and design documents;
♦ Deployment tool (iDeploy): Receive the instantiated parameter file generated by the design tool, complete the hardware, cloud platform, MANO and VNF deployment, and complete the VNF office data configuration;
♦ Test tool (iTest): After the cloud platform, MANO, and VNF are deployed, test the cloud platform and VNF through the test tool to verify whether each functional component meets the design requirements;
♦ Unified Portal platform: Manage integration project process data, accumulate integration experience, update integrated asset library, and provide capability support for the three functional components.
iDevise simplifies NFV network integration design
Devise business processes and implementation functions are as follows:

♦ Simplify design input: simplify the design input interface, and make the input of planning and design parameters more convenient through automatic configuration and combination;
♦ Reduce technical difficulty: the visual planning and design process, by solidifying the design template, makes the design process easier and reduces the skill requirements of personnel;
♦ Shorten design time: Automatically generate instantiation parameter files for all components of the integration scene, optimize configuration steps, avoid duplication of work, and make planning and design more efficient and faster.
iDeploy simplifies NFV network integration and deployment
The iDeploy business process and implementation functions are as follows:

♦ Improve deployment efficiency: support intuitive deployment preview, basic deployment input, zero intervention in the deployment process, and output a testable and acceptable virtualized environment;
♦ Improve deployment quality: end-to-end network element automated deployment, which can observe the entire deployment process in real time, support real-time query of deployment progress, exceptions, log information and reports, and ensure the entire deployment process;
♦ Simplify the deployment process: The deployment process is automated, from VIM deployment, to MANO deployment, VNF deployment, VNF and TOR/EOR basic configuration, all can be automated through automated deployment tools.
iTest Simplifies NFV Network Integration Testing
The iTest business process and implementation functions are as follows:
Figure 4: Integration Test Component iTest Business Process
♦ Shorten the test cycle: realize the automatic test of the function, reliability and performance of the hardware/cloud platform/MANO/VNF, network elements and components can communicate independently, save the test manpower and shorten the test cycle;
♦ Improve test quality: realize test plan determination, use case generation, execution, report output automation, avoid manual errors, and improve test quality;
♦ Rapid business iteration: The test case can be edited according to the actual configuration, with rich scenarios, which can better adapt to customer needs, complete the test quickly, and support the rapid iteration of customer business.
NFV project asset management realizes unified management of integrated assets
AIC tool platform supports unified access and unified management of NFV projects. The platform integrates project asset management, experience accumulation, information management and release through functions such as project library, template library, use case library, version library, and experience library, which solves the inability to effectively accumulate and accumulate experience in traditional projects such as integrated design documents and test cases , the problem of reproducibility cannot be formed.
Practical application of virtualization integration automation AIC tool in NFV network construction
At present, the AIC tool platform has been successfully applied in many NFV commercial networks and experimental bureaus at home and abroad, and has been well received by customers.
In addition, AIC tools also participated in the China Mobile OPEN-AUTO cooperation plan, and cooperated with operators to develop and verify integrated automation tools, jointly build a partner-type industrial ecology, create a new model of virtualized network construction, and help operators meet the telecommunications industry. New Era.
