1.5 FX Series Appliances

1.5.1 Theory of Operation

The FX Series ADC software can run on the FX-4010, the FX-4000, the FX-1005 or the FX-1000. The FX
Series ADC applies deflate compression, image transformation, static and dynamic content caching. To the
client, the FX Series ADC appears to be the back-end server.
The FX Series Application Delivery Controller (ADC) devices accelerate application delivery and reduce the
amount of traffic over satellite links. ADCs are single-sided (asymmetric), requiring an appliance only in
the head-end. The FX Series ADC serves as a proxy for TCP management, acceleration and offloading
server and network resources for out-bound traffic. TCP acceleration removes the time, quantity and
complexity associated with multiple short-lived connections that slow network performance and add
overhead to Web server CPU resources. An ADC terminates the client-side TCP session requests, and
multiplexes many short-lived sessions into a single longer-lived session between the FX Series ADC and
the Web servers.
WANOP Optimization and Data Compression
In addition to a one-sided configuration, the FX Series ADC can reside at the service provider head-end,
and work together with FX Series Remote appliances located at each remote site. These products provide
two-sided WAN optimization and application acceleration to alleviate the adverse effects that latency and
performance errors have upon satellite network performance. They are referred to as WAN Optimization
Controllers (WOCs).
In two-sided optimization, if a connection to the FX Series ADC is not able to be achieved by a remote
appliance, then the remote appliance will go into a "pass-through" mode where the requests will be
directed to the target content server.
Header Compression
As real time traffic moves to IP, there is a proliferation of traffic with small payloads. In this case, the
header bytes can be 2 to 4 times the number of payload bytes. For small voice packets, compression can
result in reducing the required data rate to 30 – 50% of the original. The FX aggregates packets into an
Ethernet frame and sends it to a peer, where the packets are restored.
