VSR - High Performance VPN Platform Optimized For Hybrid Broadband Networks


High-Performance VPN Platform Optimized For Hybrid Broadband Networks


Encore Networks’ VSR 1200™ is an integrated security gateway that has been optimized to support high-performance security and VPN solutions over satellite and hybrid broadband networks. With a designed based on next-generation high-performance RISC architecture and purpose-built VPN acceleration processors, the VSR 1200™ can meet the requirements of network scalability and application security for carriers and large enterprise customers.

With its built-in, field-proven ELIOS™ operating systems, the VSR 1200™ is adapted for broadband satellite-based VPN using Encore’s innovative patented Selective Layer Encryption (SLE) feature. The VSR 1200™ works across multi-vendor satellite and terrestrial networks and solves the issues of performance degradation associated with running open-standards-based IPSec over TCP-accelerated satellite connections.

The VSR 1200™ is integrated with best-of-breed IP VPN features, IP routing, advanced QoS, dynamic packet inspection firewall, embedded address management capabilities, and legacy data support via a high-density Remote Data Unit (RDU™) serial module. Such flexibility provides stateful-inspection firewall, with the scalable performance needed for the most demanding network applications.


Key Features

  • Scalable architecture and redundant power supplies
  • Proven ELIOS™ operating system
  • Innovative SLE-based VPN solutions for VSAT
  • Spoofing and conversion of legacy data applications to IP
  • Advanced Quality of Service settings
  • Support of DHCP, NAT and Private Address Translation (PrAT)


Key Benefits

  • Allow the delivery of reliable and high-performance VPN solutions over hybrid networks (terrestrial, wireless, and satellite)
  • Enables value-added services and applications to enterprise customers
  • Provides interoperability with key satellite-modem vendors to produce high-performance VPN over satellite
  • Provides solutions for vertical markets, including banking, travel, utility, and lottery
  • Meets the requirements of mission-critical applications such as VoIP and video over IP vendors TCP spoofed (PEP)
  • Allows dynamic IP address configuration management and administration



Scalable Architecture

The VSR 1200™ is designed based on next-generation hardware, RISC-based architecture, and high-performance packet and encryption processors. Such scalable architecture allows service providers to support small, medium, and large-enterprise customers running bandwidth-intensive applications over satellite networks.


High-Performance VPN Solutions
Encore Networks’ patented Selective Layer Encryption capability, integrated on top of feature-rich ELIOS™ operating system, provides channel-efficient VPN solutions over satellite and hybrid networks. Such implementation interoperates with different satellite-modem vendors and IP Performance Enhancing Proxy (PEP) providers.


The convergence of Legacy Applications
The convergence of legacy data applications to broadband IP networks is feasible with the VSR 1200™ via the use of the high-density serial module RDU™ (2 RDUs per VSR-1200™). Each RDU™ supports up to 12 serial ports. A smooth migration strategy solution for both remote terminals and legacy hosts is supported via spoofing and conversion of legacy and SCADA protocols including SDLC, Bisync, X.25, polled async, DNP, CDC, and X.42.


Easy Installation and Management
The menu-driven user interface, support of SNMP management, and plug-and-play features allow for remote configuration and support from a centralized Network Operation Center (NOC). A multi-level password-protection scheme limits access to authorized users and personnel.
