A Component-based Middleware for Network Function Virtualization

A Component-based Middleware for Network Function Virtualization

A Software Definition Network (SDN) supports programmable, flexible and convenient network management. Network Functions Virtualization (NFV) virtualizes multiple types of network services, reducing the complexity of network construction. The above two technologies work together to improve the efficiency of network construction and facilitate network maintenance. This study concerns the design of component-based middleware with high performance and reliability for NFV. The middleware responds to user needs in configuring network functions. When the load changes, it adjusts the virtual machine configuration to ensure that users can receive quality service. The proposed middleware platform includes the network, NFV and a Resource Manager to improve the operational effectiveness and reliability of the network. Network performance is analyzed identify the proposed method that minimizes the cost of construction a network resource service chain. The proposed middleware can eliminated the service bottleneck of NFV, and the results of the performance analysis demonstrate that it improves network performance by 30% and reliability by 1.5%.
