Australian Satellite Communications Pty.Ltd.is pleased
to announce services on our newly installed iDirect
hub, an improved broadband VSAT solution. ASC has
selected iDirect Technologies, a leader in enterprise
broadband over satellite solution for over 3 years
with over 110 Hubs sold in about 40 network operators.
iDirect’s technology provides one of the most
scalable, flexible and bandwidth efficient products
in the industry, for a complete broadband VSAT solution.
iDirect’s technology allows ASC to create and
implement multiple service plans to support different
types of enterprises, each with their own requirements.
Using iDirect’s technology ASC will not be
limited to a single type of topology. One can implement
a star, mesh or SCPC technology within the same hub
chassis. iDirect provides standards based IP over
Ethernet thus making it easy to integrate into enterprise
customer networks. iDirect’s advanced patent
pending technology allows ASC to support real-time
and non real-time applications even within shared
networks, using our Real-time Traffic Management feature
set. This ensures the best VoIP support within a shared
TDMA system even in double-hop configurations (in
a star topology, single-hop in mesh).
iDirect also allows ASC to implement “real”
private networks, in addition to encryption, to ensure
secure connectivity for its customer base, all within
one hub platform. This tremendous scalability will
save ASC to reduce its capital and operational costs,
as it grows its customer base and types of customers.
The iDirect system is a satellite based IP solution
that operates in a star topology. The star topology
consists of a Hub and multiple Remotes. The system
is a 2 way broadband network solution with all traffic
on the outroute or downstream broadcast over a TDM
carrier. Remotes pass traffic to the Hub on a shared
inroute carrier using iDirect’s highly differentiated
Deterministic TDMA (D TDMA) access scheme. The iDirect
system is ideally suited for networks with traffic
patterns that follow a hub-to-spoke model and traffic
that is bursty in nature. The system was designed
and developed to optimize the transport of TCP/IP
protocol traffic over satellite. The highly efficient
D TDMA achieves efficiencies that are close to 98%
of the payload bandwidth.
The iDirect system has features and controls that
allow it to be easily configured to deliver application
QoS (Quality of Service) and other traffic engineered
solutions to the users. The iDirect system also provides
TCP and Web acceleration that supports line rate TCP
throughputs in BOTH directions, even to only one TCP
session in the network. Other features of the system
include optional 3-DES link encryption that encrypts
the Remote, local DNS cache on the Remote, dynamic
and static IP routing, end-to-end VLANs and mobile
The highly scalable and flexible broadband Hub has
been designed to support multiple outroutes and inroutes
within a single Hub Chassis, while simultaneously
enabling the connection of up to 5 different satellites.
This architecture provides significant cost savings
to the network operator, because they can support
multiple footprints without incurring the cost associated
with multiple Hubs.
The iDirect system is highly accessible and reliable,
even with smaller antennas (when compared to competitive
solutions). The system has built-in automatic inroute
power control that ensures connectivity even through
severely degraded weather conditions.
iDirect's current suite of products includes the
Series 3000 and 5000 Satellite Broadband Router, Hub
Chassis, Universal Line Card, NMS Server and iDirect’s
Network Management Software Suite, iBuilder, iMonitor
and iSite. Together, they enable the configuration
of a teleport gateway to allow for the provisioning
of satellite transponder capacity for the uplink and
downlink to a small transceiver. (In some instances
the dish at the site of an enterprise could be as
small as 0.75 meters.)
VoIP over iDirect VSAT System
iDirect Technologies broadband IP VSAT network system
effectively transports VoIP traffic over satellite.
The obstacles associated with this challenge have
been addressed using iDirect’s highly differentiated
real time traffic management (RTTM) feature set. The
RTTM feature set is an inherent part of iDirect’s
operating system software (iDS) and has been specifically
designed to support applications such as voice that
are not tolerant of delay, requiring specific network
conditions to perform properly. Traditionally, transporting
voice over satellite has been supported through implementation
of Single Channel Per Carrier (SCPC) technology ostensibly
creating a continuously connected environment similar
to a dedicated private line circuit. Using SCPC to
support enterprise VoIP needs is bandwidth inefficient
and therefore a costly solution. Only iDirect’s
system delivers “toll quality” digital
telephony to the enterprise customer over a highly
cost effective shared bandwidth medium employing the
following relevant RTTM features:
- Application QoS and Prioritization at the remote
on the TDMA Inroute.
- Segmentation and Reassembly (SAR) at the remote,
or what is more
- popularly referenced as Fragmentation and Interleaving.
- Committed Information Rate settings for the remote.
- Dynamic CIR and Application Triggered Dynamic
- Network QoS at the network level.
- Feathering of Timeslot allocation.
- Application QoS and Prioritization at the Hub,
on the Outroute.
- SAR at the Hub, on the TDM Outroute.
- CIR at the Hub, on the TDM Outroute.
