Building the carrier grade nfv infrastructure
This document discusses an all-in-one rack-based solution for network functions virtualization infrastructure (NFVI) that aims to address problems with traditional NFV deployments. It proposes a rack-based delivery approach with integrated computing, storage, networking hardware and software components including virtualized infrastructure manager, platform infrastructure manager and virtual network functions. The solution aims to reduce costs and complexity through pre-integration, standardized racks and centralized management. Future plans include further standardization, field testing and collaboration with industry partners.

- 3. 3 Problems We Met Someproblems from the NFV decoupling test • Too many hardware and software products to choose from • Form of hardware varies, no unified way to configure and obtain the information • The process of deploying, installing, integrating are repeated and error-prone • Lack of standard interface, difficult to integrate different vendor’s product • No centralized NFVI management system, not good for operation and maintenance In order to re-architect our network, we need to do lots of works But it’s time consuming and resource consuming What can we do?
