Functional area
ESR series routers are universal hardware platforms capable of performing a wide range of tasks related to network security.

ESR-20 is universal service routers designed according to the requirements of energy and oil and gas industries. The devices support advanced routing functions, geographically-distributed networks and network security functions.

Performance
The key elements of ESR routers are data processing hardware acceleration means that ensure a high level of performance. Hardware and software processing is distributed among the units of the device.

Typical tasks performed by ESR-20:
– Data routing
– Construction of secure network perimeter (NAT, Firewall)
– User access control
– Organization of secure network tunnels
– Construction of distributed private networks, integration of remote offices into single network
– Filtering of network data by various criteria
– Interaction with the existing customer network infrastruc-ture by the use of communicating channels types defined by industry standards - voice channels, leased and dial-up lines, E1 flows.
