The Problem
In the satellite industry,
users often run into situations that
are unique to their network applications.
One typical example is running a
VPN over or through the VSAT link
from remote sites to headquarters
(see diagram below). The most common
form of VPN is IPSec, either 3DES
or AES, both of which are recognized
by FIPS (Federal Information Processing
Standard) as a secure VPN solution.
Customers running a VPN over VSAT
generally find a loss of throughput
which can result in as much as a
70% decline in available bandwidth.
This is the main reason many of today’s
latency sensitive applications fail.
When running any IP
based application over VSAT, all
service providers have TCP acceleration
which is required to support basic
TCP communications. Without this
acceleration, the IP sessions would
time out due to basic physics and
the height of the satellite with
respect to the VSAT. This acceleration
is commonly comprised of processors
called Performance Enhancing Proxy
Servers or PEP. All VSAT service
providers have a similar process
but all are unique to their network
topology. |

The
Encore Solution
Encore Networks brings
its patented IPSec VPN solution to
the VSAT industry called Selective
Layer Encryption (SLE). SLE is designed
to enhance VPN and work in tandem
with PEP providing fully encrypted
IPSec data. SLE can be found in all
of Encore's VSR™ and BANDIT™ routers.
The VSR™ and
BANDIT™ line of environmentally
hardened (rugged) routers offer superior
performance improvements over a common
VPN. Customers have realized the
full potential of the VSAT link with
less than a 5% net loss of bandwidth.
SLE leverages the inherent acceleration
provided with the VSAT service which
maximizes throughput. For example,
in File Transfer Protocol mode (FTP),
SLE performs as well as running non-encrypted
data up to 10M files. This is documented
in Encore’s rigorous certification
process with all VSAT carrier partners.
If you are looking for high performance
in your VSAT network along with a
secure VPN, Encore Networks provides
the best choice on the market today.
