Expand Networks
Integrates Rocket Science to Improve
Application Performance Over
Satellite Communications
Expand Networks, is
addressing application performance
issues over satellite links enabling
global enterprises to reliably
deliver all business applications.
With increasingly dispersed
offices in remote locations,
satellite networks have become
common practice to assist
organisations in business agility.
However, the design limitations of
high latency and packet loss over
satellite networks severely affect
application performance resulting in
delayed file transfer, slow response
times and reduced remote user
productivity. By deploying the
Expand Compass platform with
integrated Space Communications
Protocol Standards (SCPS), all
applications are accelerated over
satellite networks guaranteeing
workforce productivity and end user
satisfaction.
SCPS is a collection of
standards-based TCP enhancements
designed and developed by NASA to
overcome the shortcomings of TCP in
the stressed environment of
satellite communications. Expand has
truly integrated SCPS with the
multiple technologies of the Expand
Compass platform in a single
platform, to mitigate against the
negative impact of satellite and
accelerate applications to remote
users, guaranteeing improved
performance and productivity.
“When
SCPS is combined with compression,
byte-level caching, QoS and other
forms of caching techniques
integrated in the Compass, it
ensures that Expand delivers as much
‘virtual’
capacity as possible while
mitigating the effects of TCP
latency, and gaining complete
control with the QoS, and crucially,
all in one device,
” said
Adam Davison, VP Sales, EMEA, Expand
Networks. “
Compass excels in satellite
environments with the ability to
accelerate all business applications
ensuring they achieve maximum
potential resulting in improved end
user productivity and reduced
network costs. ”
When deploying Compass,
compression features increase
network capacity on average by as
much as 100-400% removing
congestion, and acceleration rates
of 300-500% address protocol
limitations, reducing chattiness and
lessening latency. In addition, QoS
services prioritise business over
non-business and other web traffic
to eradicate congestion for mission
critical applications.
Many organisations around the
world have already experienced the
tremendous improvement in
application performance and
capabilities over satellite links
when deploying the Expand Compass
platform such as Boeing Integrated
Defense. According to Dennis Watts,
project manager,
“ Efficiency is an integral
part of our evaluation and it is
important to have strong compression
functionality along with QoS. Expand’s
Compass Platform possesses a robust
architecture in addition to their
experience in government satellite
markets.”
In addition, Kenn Devine, Project
Team Leader and Manager of
Information Systems, Burns and Roe
Services Corporation said
“ On
average, we experience about a
four-fold average bandwidth
acceleration across the 512Kbps
satellite link, with peaks of
1,200%. Across the DSL sites, we
experience an average of about 300%
with peaks to 800%, depending on the
site. There was also a 400% increase
in network throughput, 100% for
speed performance (back-up, file
transfers) and a 50% bump to the
positive in network capacity.”
