The article analyzes the main approaches to ensuring the survivability of computer networks. It is shown that the survivability methodology that is applied to computer systems is partially different from that used in computer networks, which is associated with the active development of virtualization technologies. The purpose of the article is to develop a method to ensure the survivability of a computer network, which is an information environment for guaranteed provision of digital services, by using virtual tunnels based on the principles of VPN tunneling to delegate "white" IP addresses to computer networks, or routing schemes for data flows when using internal VPN servers with a single "white" IP address. The results obtained make it possible: to formulate a scientific problem with the formalization of the necessary technical requirements for the developed computer network; develop an application solution for ensuring the survivability of a computer network based on the use of multiple VPN tunnels; conduct a series of experiments to study the effectiveness of using various network protocols in VPN tunnels; to create a basis for further development of the methodology for ensuring the survivability of computer systems to ensure the continuity of network infrastructure management processes. The studies allow us to conclude that the proposed method can be used at the design stages of computer networks when determining redundancy indicators when implementing the principles of managing network elements such as servers, gateways, technological equipment, etcDownloads
