Network function virtualization (NFV) intermediate system framework

Abstract

The invention discloses a network function virtualization (NFV) intermediate system framework. The framework comprises NFV infrastructure and an intermediate system, wherein the intermediate system is in a communication connection with the NFV infrastructure, and is used for acquiring information in an NFV network to make a decision and output the decision to the NFV infrastructure; and the intermediate system comprises a network management system which is used for partitioning a NFV environment region, and configuring network functions of different regions as required, an NFV management system which is used for managing running modes and flows of all virtual network functions in the NFV environment region, partitioning priority levels of users, and configuring virtual machines of corresponding efficiencies according to the priority levels, and a resource management system which is used for monitoring and adjusting the quantity of users, load transferring and switching of the virtual machines according to the use conditions of the virtual machines in the NFV environment region. Through adoption of the NFV intermediate system framework, a network environment which is easy for a network manager to manage and low in human resource and building costs is provided; the network service quality of the users is improved; and network environment building and managing difficulty is lowered for the network manager.

Description

technical field [0001] The invention relates to a network technology, in particular to a network function virtualization intermediary system architecture. Background technique [0002] At present, in the traditional network, it is not easy to modify, maintain and manage the network after the network is built. When there is a need for new network functions, the configuration of the network needs to be modified. If NAT needs to be installed, the back-end setting of the NAT device needs to be modified. The network connection configuration and settings of the location, as well as the settings of the end-user connection, and if it is necessary to modify the network functions of the central network, such as a firewall, it is not only the terminal design that needs to be modified, but also a larger network design that needs to be modified. This process is prone to human error, and there is also the possibility of network paralysis due to incorrect device settings. When developing ...

Problems solved by technology

However, most of the current network construction methods are based on hardware (Hardware-Based) construction methods. There are often compatibility problems between different hardware devices, resulting in the situation that they cannot communicate with each other. This will cause network service operators to plan for diversification and When customizing network services, it often takes a lot of time and cost to find a suitable solution. While the number of dedicated hardware devices for network services increases, it also increases the complexity of the network environment that needs to be built. When deploying The difficulty of operations such as integration and maintenance has also increased relatively, resulting in the traditional network model becoming increasingly unable to meet the needs of users for the network
