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.
