NETWORK INTERACTION IN VIRTUALIZED ENVIRONMENTS AND FEATURES OF VIRTUAL STAND DEVELOPMENT

Abstract

This article describes a virtual bench developed by the authors for studying network interaction in virtualization and containerization environments. The functional diagrams of the two modules of the stand are presented, as well as the exact characteristics of the software and hardware used in the work. The study of network interaction is carried out in a certain complex of proprietary and free software, which distinguishes it from previous studies. To build a virtual stand, the VMWare system was used, with the help of which 2 stand modules were created. The hypothesis of the research is that installed DPDK libraries on hosts and VMs and containers, as well as configuring OvS will increase network performance, which includes bandwidth and latency parameters. Network research is carried out in two modes of operation using the software switch Open vSwitch and DPDK libraries. The results of the study and the authors recommendations are given at the end of the work. Also, the key features of configuring virtual machines, containers and software switch, which are the main objects of research, were described. Further research on the topic involves defining a set of best practices for configuring all components of the network infrastructure (including the number of numa nodes, cpu pinning topology and the amount of huge pages), and making recommendations for choosing the main parameters of VMs and containers.
