EVALUATION OF PRODUCTIVITY VIRTUALIZATION TECHNOLOGIES OF SWITCHING EQUIPMENT TELECOMMUNICATIONS NETWORKS

Abstract

Background. To date, the effectiveness of the use of virtualization technologies for the deployment of the organization's infrastructure of any complexity is beyond doubt. First of all, it is a gain due to the rapid deployment of the necessary infocommunication services, flexible scaling of the system without replacing the hardware server platform, which was purchased earlier and has a sufficient "estimated" resource. These approaches are commonly used
by modern telecom operators to build their telecommunications networks or to expand the range of new services. In turn, the rapid development of virtualization technologies such as hypervisor-based technology for mutual isolation of virtual machines and container virtualization based on Docker, requires further research on the effectiveness of their use.
Objective. The aim of the article is to determine the effectiveness of container virtualization and virtual machines.
Methods. Creating a segment of the IP telephony network for testing the load of IP PBX (PBX) Asterisk on a virtual machine and container with test calls.
Results. The share of CPU usage when using Elastix IP-based PBX based on a virtual machine is higher by an average of 5% of the container. Instead, the use of RAM is very different. In the case of virtual machines, it is several tens of times larger, which will obviously affect the operation of the system as a whole.
Conclusions. The study showed that the use of IP PBX (PBX) Asterisk on a virtual machine compared to the container takes up more virtual server resources, but when loaded with simultaneous calls is less stable.
