Typical tasks performed by service routers
  • Data routing
  • Construction of secure network perimeter (Firewall)
  • Network attacks prevention and monitoring (IPS/IDS)
  • Service quality monitoring (SLA)
  • Filtering of network data by various criteria (including filtering by applications)
  • Organization of secure network tunnels between different offices of a company
  • Remote connection of staff members to office
  • Management and distribution of Internet channel width within an office by using QoS
  • Organization of redundant connection (by means of wires or 3G/LTE modem)
  • User termination and bandwidth limiting – BRAS (IPoE)
ESR-21 are multipurpose service routers developed in compliance with requirements of energy and oil-and-gas industries. The devices support advancedrouting, WAN organization and network security functions.

The main feature of ESR-21 is the presence of additional RS-232 ports that can be used for implementing additional functionalities – remote device management via console (AUX mode) and connecting wired/GSM modems to firewalls.
