Secure data transmission in geographically distributed information systems in ophthalmology based on domestic equipment

Relevance. Currently, to ensure secure data transmission in geographically distributed information systems, including in ophthalmology, in particular secure data transmission of telemedicine consultations, when exchanging data between various healthcare institutions, when transmitting data during multicenter clinical trials, scientific developments, Multipoint Private Network (DMVPN) technology is widely used. DMVPN allows you to significantly reduce the load on equipment when organizing the work of remote offices. This «overlay» VPN reduces the participation of the provider in organizing a connection with a large number of users compared to analogues of the «peer-to-peer» type. Purpose. To evaluate the features of the transition to Eltex equipment when building a DMVPN in geographically distributed information systems in ophthalmology. Material and methods. Eltex ESR-200 routers were used as a laboratory stand. To measure the throughput of routers, the Iperf3 software product was used – a cross-platform console client-server program. Results. This article provides an assessment of the throughput of Eltex equipment when building secure DMVPN tunnels. Conclusion. Eltex equipment is productive and effective for solving the problems of building secure DMVPN tunnels to ensure secure data transmission in geographically distributed information systems in ophthalmology.
