The
LinkXX is a high performance, self-contained
secure multimedia communications server and router
with an integrated satellite WAN and bandwidth manager.
|
The LinkXX
is designed for deployment in the terrestrial
segment of space telecommunications systems.
It is an extremely flexible and powerful system
tool for use in the design of advanced networks,
enabling multiple service offerings over a single
infrastructure. The LinkXX system presents
an integrated approach to the never ending search
for speed, efficiency and cost reduction in
the delivery of services via satellite. At first
glance, it may look like a typical VSAT product,
however, the LinkXX is in a class by
itself, with performance in the near-gigabit
class.
|
The LinkXX approach
is contrary to that of the satellite communications
industry mainstream. The industry has traditionally
taken a top-down approach to integration of
satellite terminals with LANs and WANs by attempting
to IP enable existing satellite network management
systems (TDMA and DAMA) and modifying existing
earth station hardware. LinkSat has taken the
opposite approach. It has built a comprehensive
LAN / WAN solution from the ground-up by satellite
enabling LAN servers and routers. This melding
of technologies has proven to have many benefits
and has given the developers totally new insights
into the interaction of system components.
|
| |
The
advantages of this approach are numerous: |
1 |
All-in-one
terminal |
|
Eliminates
the need for gateway routers and servers |
|
Integrated
modulators, demodulators, data compression,
data security, and satellite bandwidth
manager |

class router with throughput measured in the
100’s of megabytes per second |
|
| 2 |

PLATFORM ARCHITECTURE |
The LinkXX
is a unified platform for a family of
products. The highly modular architecture
can be adapted for a host of different
applications using software and hardware
plug-in modules. The product's application
depends on which software and hardware
modules are installed in the router. Modules
for new applications and changing standards
are easily added or modified, making the
LinkXX extremely flexible and
virtually future proof.
|
| The LinkXX
uses a plug-in architecture to customize each
network node for specific applications. Plug-in
modules include both hardware and software
modules that adapt the LinkXX for
specific applications. |
|
|
|
| LinkIP
-- IP Data and Digital Video applications
|
| Data
applications include all layer 2 or layer
3 digital data network applications, the majority
of which are IP based: |
| 1 |
Corporate
LAN/WAN: |
This includes
private networks for bridging or routing
of corporate LANs, transactional networks
for ATM, credit card verification, etc.
Services provided can include Internet
access, email service, Intranet service,
videoconferencing, and voice service.
|
| 2 |
ISP Backbone Access: |
This application
provides a tier one POP connection via
satellite for Internet service providers
who do not have access to a terrestrial
connection, or who want a diversity backbone
connection to enhance the reliability
and throughput of their existing terrestrial
connection.
|
| 3 |
VoIP: |
Voice over
IP provides satellite connection to a
gateway for international, or domestic,
long distance service providers.
|
| 4 |
SCADA: |
A fully integrated
spoofing approach to the most common SCADA
protocols is a market niche that is underserved
and deserves attention. This application
is of special interest in the oil / gas,
and electrical industries.
|
|
| LinkDV
-- Digital Video Delivery applications |
| |
Video applications
involve delivery of video content using
MPEG2, MPEG4, or other video compression
schemes for both broadcast video and video-on-demand:
|
| 1 |
Video
Distribution: |
This application
addresses point-to-point or point-to-multipoint
broadcast or re-broadcast of video content,
as well as store and forward delivery
of video content. It also includes delivery
of video programming to DSL head-ends
for distribution to subscribers of CLECS
offering multi-channel television service
over twisted pair infrastructure.
|
| 2 |
Video Contribution: |
This covers
applications where television network
affiliates send content back to a network’s
central studio for editing and/or re-broadcast.
|
| 3 |
DSNG / Video-on-demand: |
Covers video
transmission services that are normally
provided on an ad hoc basis, including
digital satellite news-gathering (DSNG)
vehicles and flyaway terminals used to
cover breaking stories, sporting events,
etc.
