Research And Implementation Of Task-Oriented Container Network Control Technology

Data center uses the virtualization technology to construct computing,storage and network resources into a dynamic virtual resource pool,and uses virtual resource management technology to realize automatic deployment,dynamic expansion and on-demand allocation of cloud computing resources,so that users can adopt on-demand and get resources in a pay-as-you-go manner.However,traditional virtualization technology(virtual machine)is difficult to adapt to current development needs.Virtual resource management has become a hot and difficult point in data center construction.At the same time,virtual resource management has caused problems such as low utilization of cloud computing resources,application and platform cannot be decoupled,strong environmental limitations on application motion,and reduced control of operation.With the gradual maturity of container technology,it has better performance than virtual machines occupying less resources.The advantages of lightweight resource management and second-level startup make the deployment of the large-scale container cluster regular.Using containers to instead virtual machines in large-scale cluster deployment has become an inevitable trend.As a lightweight virtualization technology at the operating system level,the container is often used in scenarios such as large-scale deployment and elastic scaling.As a result,the degree of dispersion of the container network is significantly higher than that of the traditional virtual machine network.The deployment of large-scale container cluster becomes a difficult problem.This paper proposes a network control architecture for large-scale container clusters based on the Vxlan-based Overlay network model and macvlan-based network system.The three aspects,such as flexible networking,intelligent adaptation and isolation control,are going to solve key problems in large-scale container cluster.For the key issues in container networking,the solutions proposed in this paper are as follows:1.Build a network control architecture in the large-scale container cluster environment.2.Design container flexible networking technology,realize flexible network adaptation and migration of nodes based on Vxlan-based overlay networking and macvlan-based network system.3.The network intelligent adaptation technology is used to realize the automatic selection of the network model,based on the quantitative analysis of the container network characteristics,thereby improving the efficiency of container networking.4.Using namespace technology as the isolation basis,adopting VLAN division and iptables management technology to implement container network isolation control,thereby improving the security of the container network.The experimental results reveal that the network control architecture proposed in this paper can achieve the large-scale cluster dynamic networking of containers,the rapid division of VLAN,the stable migration of network nodes and the precise isolation control of node communication according to the characteristics of the network.
