Technologies that Optimize Satellite Bandwidth Acceleration
Traffic Shaping with ACM Tracking
Traffic is classified and prioritized at layers 2-5. With three levels of filters and the ability to shape with CIR’s
and MIR’s at each level, traffic can be managed across multiple geographic locations using point to point and
point to multipoint links. The traffic shaper supports links with ACM by reading the data rate from the modem
and adjusting to that rate. There are presets for EF Data modems that support ACM. This feature is available
as either stand-alone, or as part of the full WAN optimization product
Transparent Assured Delivery
With flexible options for in-line or Cisco’s Web Cache Communication Protocol (WCCP), the FX Series devices
deliver unprecedented transparent optimization. End-to-end assurance is maintained for all applications
providing complete transparency and the ability for existing Quality of Service (QoS) and network visibility
management programs to continue monitoring the health of your network.
Optimize VLAN Trunked Data
All appropriate Layer 5 and Layer 7 optimizations are available for tagged VLAN data, preserving or recreating
the VLAN tags for optimized traffic. This includes HTTP caching as well as de-duplication. Caches are
maintained by appliance and by VLAN. Appropriate traffic can be shared between VLANs on the same
appliance. In addition, the FX-1010 will support up to 8 LAN ports, each of which is tagged and passed to the
WAN trunk.
Multicator
The FX Series supports a reliable multicast. This is designed to work in a mesh network, but will also work in a
hub/spoke network. In the mesh, any device can be a transmitter with the remaining devices being receivers.
Multiple devices can be transmitters. The transmitter function is time shared, with a second device being
given permission to transmit after the first is complete. This can work in a hub-spoke network where typically
the ADC would be the transmitter, although this is not required. The process is to FTP a file from the client into
the transmitter’s inbox, that file is transmitted reliably in a multicast to all of the receivers. Once transmitted,
the receivers FTP the file to a specified server.
Redundancy and Fail Over
Redundancy is critical to 24/7 availability, and the FX appliance is designed to handle redundancy and fail over
in two different ways; inline and routed. The inline configuration is used when operating in conjunction with a
CEFD modem operating with 1:1 redundancy. WCCP (Web Caching Communication Protocol) is used in routed
mode to allow N devices to serve the function of any M devices, resulting in M: N redundancy. The inline
configuration has a primary and a redundant device in series, the redundant takes over whenever the primary
fails.
Management
The FX platforms provide total insight through real-time information including over 100 real-time statistics
providing extensive details on all inbound and outbound traffic. Historical data for days or months are easily
viewed via online graphs, simplifying capacity planning, trending, network issues, and application
troubleshooting. Management information can be obtained via an intuitive Web GUI or SNMP. The updating
for the FX Series Remotes is automatic. The FX Series remotes poll the FX Series ADC for updates. When the
ADC is updated; each remote will download the update and automatically update itself.
