Enterprise Connectivity

DIALOG
Elevating Enterprise Private Networks
with Cost-effective Satellite Services
The success of today’s organizations and enterprises highly depends on reliable and
secure connectivity. Enterprise connectivity exists between different branches,
between a central office and geographically widespread points of activity and between
an enterprise and the public internet. The connectivity enables faster, more secure
transactions and improved productivity by sharing information between entities,
no matter where they are.
By offering an extremely cost-effective terminal as part of a scalable network solution,
attractive IP services can be deployed complementary to terrestrial infrastructure:
• As a backup service for the terrestrial network providing business continuity
• As the main connectivity service in case no adequate terrestrial infrastructure is
available providing a way to extend the operation to any location
• As a highly efficient multicasting data/video service for media-rich collaboration
services, video conferencing and financial trading applications
ENTERPRISE
CONNECTIVITY
ST Enigneering iDirect offers a
cost- effective broadband
connectivity for a wide variety of
professional applications on a
single platform.

Applications
Typical enterprise applications can be served with different
transport IP services. The service properties vary in the need for
encryption, the need for acceleration and the sensitivity to
latency and jitter.
Efficient Carrier Grade Infrastructure
Our Newtec Dialog® platform provides the means to establish
an “always-on” two-way IP connectivity completely independent
from existing terrestrial networks.
The basic IP connectivity between hub and modem is extended
with Quality of Service (QoS) in forward and return allowing
the deployment of different services. The gateway contains
management functionalities to monitor, configure and control all
worldwide remote sites.
Bandwidth Efficient Technologies
To make satellite an attractive alternative for enterprise
connectivity, our Broadband Solution implements the most
bandwidth efficient technologies, such as
• DVB-S2X Wideband ACM forward link, with Equalink® 3
predistortion and Clean Channel Technology® (low roll off)
• High Resolution Coding (HRCTM) Mx-DMA® return link
• Quaternary Continuous Phase Modulation (4CPM) MF-
TDMA return link
• Embedded IP traffic enhancement
The 4CPM modulation combines bandwidth efficiency of linear
modulation, as in the DVB-RCS standard, with a lower cost
terminal.
Hub Redundancy
The hub provides internal and interface (RF, IP, power supply)
redundancy. The internal redundancy is conceived to allow full
hot-standby redundancy without any single point of failure. If
there would be a failure, a switch is automatically performed.
High end-to-end service resilience and disaster recovery can be
further assured using two hubs configured in a geographical
redundant configuration, where each hub can serve as backup
for the other.
Network Optimization
ST Engineering iDirect’s Network Optimization technology offers
up to 35% bandwidth reduction for typical applications such as
file downloading, web surfing and content streaming. The
reduction of traffic in both volume and number of packets is up
to 20% in the forward and up to 90% in the return. The
bandwidth savings of forward acceleration is today limited since
most content is pre-compressed. Bandwidth reduction is mainly
achieved through overhead reduction. The gain can also be
viewed from the user experience point of view. The load time of
a webpage is reduced by up to 60%, while a file download time
is reduced by up to 90%.

Offering Business to Business Services
Service providers, corporations and organisations are all faced
with different security and scalability needs. Some organisations
will have high needs for security that they will fully take care of
themselves. Others will have enough trust and confidence that
they will leverage the services offered by the service provider.
On a VSAT platform different network architectures can coexist
on the same platform, providing service diversification. Service
providers can optimize CAPEX and OPEX by offering enterprise
connectivity services for multiple entities in a shared platform.
This helps service providers struggling to strike a balance
among their biggest business concerns - capacity, scalability,
customer satisfaction and cost.
Internet Access for SOHO and SME
Small offices are typically looking for pure broadband access
with main office applications like web surfing, VOIP and email.
An architecture where all terminals belong to the same network
is ideal to offer internet access services for Small Office and
Home Office or Small & Medium Enterprises. In this
configuration our Dialog terminals consume only one public IPv4
address and IP address management is simple. A DHCP server is
integrated in the modem assigning the addresses to the devices
connected to the modem. All payload traffic is encrypted and
fully accelerated.

Internet Access for SOHO and SME
Enterprises or larger organisations have typically different needs
for their communication infrastructure. First of all they need
more public IP addresses in order to connect their own servers to
the internet.
Our Dialog configuration offers full routing capabilities on the
modem.
Private Networks for Large Enterprises and
Organisations
A network that connects the numerous sites of a distributed
enterprise using a shared communication platform is a Virtual
Private Network (VPN). These VPNs provide the benefits of
dedicated networks but not the associated cost. Administrators
can easily create and modify the Virtual Network (VN)
environment.
In a VN context, a key requirement is network isolation. This
means routing and forwarding tables used by one VN should be
able to be isolated from those used by other VNs. The Virtual
Routing Function (VRF) creates multiple virtual routers in a
Dialog hub to realise multiple VPNs. On top of the network
isolation, the Dialog platform offers further security measures
such as AES encryption using X.509 digital certificates.
Network Isolation
Service providers can optimize CAPEX and OPEX by offering
enterprise connectivity services for multiple entities in a shared
platform. Figure 3 depicts two isolated enterprise networks
connecting a headquarters with its branch offices. The hub acts
as a router with multiple VRF functions creating fully isolated
virtual networks. Service OPEX is reduced because all forward
traffic is shared on the same forward link.
MPLS Integration
Multiprotocol Label Switching (MPLS) is the underlining
technology that enables service providers to offer customers
high-speed private networks.
Service providers can easily integrate their MPLS networks with
the Dialog platform. This way, a customer’s remote location can
be integrated with the rest of their sites to an MPLS backbone. A
network in this configuration can eliminate the need for
encrypted VPNs and multiple-hops between remote locations
and headquarters. This configuration also allows latency
sensitive applications such as video conferencing and VoIP to be
used between multiple sites.
An MPLS Label Edge Router that is connected to the hub can
be configured to classify and push MPLS labels onto the packets.
This classification can happen either on Source or Destination IP
address or 802.1Q VLAN tags coming from the hub.
Layer 2 Bridging
Service providers can offer a layer 2 based service to customers.
Using a layer 2 bridging service, customers no longer need to
align the configuration between the corporate network and
the service provider network layer 3 configuration. All layer 3
traffic and routing is handled fully transparent over the layer 2
bridge. As a result it provides maximal network flexibility
and transparency for the end customer.
Additionally, using the layer 2 bridging service providers can
deliver new types of high throughput services either as layer
2 or as more advanced layer 3 services supported through a
customer premises router.

Offering Business to Business Services
More than ever, enterprises require reliable network
connectivity. It is especially important for remote offices that
need to access other sites, headquarters and public cloud
services where information resources exist. In such cases WAN
redundancy is a key requirement for business continuity plans.
Satellite networks have the distinct advantage in this
setup of being independent of landline infrastructure,
which could be affected by accidental cable cuts or
natural disasters.
Service providers that want to offer a satellite business
continuity solution, can do this in a cost effective way using a
combination of the MDM3310 or MDM2510 IP Satellite Modem
and Mx-DMA technology resulting into the following benefits:
• High bandwidth on demand with the highest efficiency
• Advanced QoS to support data, VoIP and video applications
• Authentication & encryption
• Embedded acceleration and compression
IPv6 Support
The single biggest argument for IPv6 today is “business
continuity”. The public IPv4 networks, which most organisations
use today, have nearly run out of unique numbers. Depending on
the region you live in, this has already happened. To preserve the
capabilities and value that we enjoy today, we have to adopt the
new protocol.
Migration Scenario Using Dual Stack IPv4/v6
The system supports networks where both IPv4 and IPv6 access
is needed. In such cases, an IPv6 network can be merged with an
existing IPv4 network to create a single, logical dual-stack IPv4/
IPv6 network. Hosts behind a terminal in that dual-stack network
can have both IPv4 and IPv6 access.
IPv6 Remote Networks
With the larger address space inherent to IPv6, addresses within
a network can be allocated more effectively in a hierarchical
fashion. The IPv6 routing functionality is extended with IPv6
prefix delegation support as a way to centralize and delegate IP
address assignment.

Premises Based VPN Solutions
In some cases, enterprises want full control over their network
security and for example, premises-based VPN solutions, such as
IPsec, are deployed end-to-end. IPsec supports key-based
authentication and encrypts the complete data packet — both
data and headers — and adds its own header. In doing so it
prevents Web and TCP acceleration within the network.
The impact on the performance of the network depends on the
scenario. Two scenarios are considered:
• A regional office: The VPN traffic is considered high,
meaning that acceleration of VPN traffic is required in order
to reduce bandwidth needs
• A Point of Sale: The VPN traffic is low volume traffic, cost of
the equipment is main driver
Regional Office
At the remote site a COTS VPN solution will be used and
connected to the modem. The resulting encrypted traffic is
preventing the TCP acceleration within the satellite platform.
TCP acceleration can still be applied but requires optimizing the
traffic before it is encrypted. TCP Acceleration can be
implemented using an off the shelf WAN optimizer solution at
the remote location and company headquarter respectively.
The result is secure end-to-end accelerated VPN connecting the
headquarter to regional offices.
POS Terminal
A low cost VPN router add-on sets up the IPsec tunnel with the
headquarters. No TCP acceleration is performed at the virtue of
a low cost remote site implementation.

Matching Terminal Equipment with Remote Application Needs
The Dialog IP Satellite Modem portfolio is designed to serve a wide range of applications at competitive price points in different
markets.
Different terminal configurations can be used on the same platform sharing the forward carrier. Management of the modems is done by a
single management system.
Depending on the application requirements, the amount of users or the geographical location, different capabilities are expected from a
terminal. Selecting the right mix of modem types and terminal configurations will minimize the total cost of ownership while fulfilling
all requirements.
The modems are based on flexible hardware platforms, assuring a long life time for the installed base. Modems can be upgraded over the air
when new features are introduced.
