  • WAN Gateway. The softFEP Network Front End Processor connects control centers and remote ground terminals over their wide area networks. With support for multiple protocols, the Network FEP is configurable to a range of communications system architectures.
  • Supported Devices. Network FEPs connect to modems, routers, switches, COMSEC devices, and other front end processors.
  • Serial to IP Conversion. Serial data streams are received and packetized. A configurable set of parameters allows the user to set the desired latency for given data rates, WAN jitter, and WAN bandwidth. IRIG time information can be re-generated with the original time-data correlation.
  • WAN Protocols. TCP, UDP, WANFEC, NORM, and PGM are supported.
  • Packet FEC Algorithms. WANs with high latency can utilize the softFEP Packet Forward Error Correction. The Packet FEC uses encoding and interleaving of the data streams to perform error recovery over the WAN without retransmission.
  • CCSDS Space Link Extension. Networks using SLE for communications utilize the softFEP’s SLE User and SLE Provider. There’s full support for the CCSDS standard, including both Orange and Blue Books.
  • WAN Emulation. The softFEP Network Front End Processor can be configured with a WAN Emulator for predeployment testing. The WAN Emulator allows you to characterize your system’s behavior by inducing packet loss, latency, and jitter in various network communications test scenarios.
  • Web-based User Interface. The softFEP app has a user-configurable graphical user interface (GUI) for standalone operations. The user interface runs in a web browser window enabling the softFEP to be controlled remotely. The customer can modify, change, and extend the user interface screens.
  • Software Application Programming Interface. A software API allows customers to support the softFEP app from their monitor and control application. The softFEP uses the Ground Equipment Monitor Standard (GEMS) for this interface.
