Tvirtual service router VESR in packet switching networks

Modern networks and data transmission systems are based mainly on the use of Cisco hardware, as well as (to a lesser extent) Huawei equipment. The introduction of sanctions led to the expansion of by domestic enterprises, among which the most famous is the Eltex. A serious disadvantage of Eltex when creating and debugging data networks, as well as when training specialists in operating networks and systems, was the lack of software tools for modeling network devices, such as Packet Tracer for Cisco; eNSP for Huawei, GNS3. To resolve this problem, Eltex developers created «vESR» (Virtual Service Router). The vESR router was introduced on June 6, 2023 [1]. It is designed for configuring and debugging routing, as well as protecting corporate networks. vESR is installed via Oracle VirtualBox or VMware ESXi hypervisors on the Linux or Windows system.
