OpenStack Network Extension Model Based On Vector Network And Its Implementation

In recent years,with the development of information technology,cloud computing,as a new virtualization solution,can integrate existing physical resources such as computing,storage and network to the pool of resource.And these resources can be flexibly provided to users by the internet.Among them,OpenStack,as an open source cloud computing management platform,has developed rapidly with the support of major vendors and becomed a leader in public and private clouds.However,with the increasing number of terminal devices and scale of data,the internal network of the data center exhibits the characteristics of centralized east-west traffic,variable traffic,and low end-to-end delay.However,under the resource-intensive network conditions,some problems of traditional IP network has been exposed,such as slow route convergence and no multi-path transmission,so it is difficult to meet the current cloud computing network traffic transmission requirements.Vector network technology is a new type of network architecture based on the theory and practice of the next generation network system.The vector address can be used to establish vector connection,with unlimited scalability and support for multi-path transmission.Therefore,this thesis conducts in-depth research on the physical network and virtual network of OpenStack cloud data center,and integrates vector network technology into OpenStack network system,which expands the network function and provides a new solution for improving the performance of cloud computing network.The main innovations and work are as follows:(1)For the physical network of OpenStack cloud data center,this paper designs a spine network deployment method based on vector network fusion model.This method not only has better scalability,lower implementation cost,but also can take advantage of the ability of multipath transmission to reduce energy consumption.(2)For the virtual network of OpenStack cloud computing management system,this paper implements a new virtual network model(Vnet)based on vector driver design.This model supports multi-path transmission,reduces processing delay and improves reliability of cloud network.(3)Through the improvement of the vectorization of OpenStack's physical network and virtual network,the vector communication between virtual machines is realized in OpenStack system,thus the integration of vector network and OpenStack is completed,the relevant experimental platform is built and carried out relevant experimental.The application of vector network technology in the cloud network not only provides a new solution for OpenStack network service,but also has great significance for the practical application of vector network.
