Private VSAT Networks

Developing A Private Network

In an environment fibre and ADSL are not readily available, where an organisation has complex connectivity and communications needs, VSAT networks can solve local telecommunications issues, without solutions constrained by local infrastructure. Management must decide whether they can operate key business applications over a:

Public Network with:

	Shared features
	Best endeavours rather than guaranteed performance

or if their needs demand a:

Private Network with:

	Control of QoS, bandwidth, fixed costs
	Previously only way of getting higher bandwidths

Private Networks provide:

	Site-to-site data links
	Dedicated bandwidth
	Low data rate to start the service, but a flexible expansion route to higher bandwidths
	The satellite network bypasses bottlenecks, or unreliability in terrestrial infrastructure
	Ability to run voice over the same circuit
	Potential to integrate PBX’s and short-code dialling between sites
	Ability to route all external calls via a central PBX to control costs VPN, other encryption of data possible
	Minimum latency solution for a satellite network

Topology & Connectivity

Installed networks usually grow organically and can be described by one of three general configurations which will determine the best choice of hardware for the requirement.

Networks usually begin as a “star”, where all the traffic is either for a central site, or routed through that site. (See PolarSat FlexiDAMA)

As regional offices develop, there may be congestion, or simply additional functionality needed at a regional office, so the network may become a partial mesh. (FlexiDAMA can also fulfil this requirement)

Finally the applications (multimedia) or the volume of network traffic may demand a mesh topology.(See PolarSat VSAT PlusII)

Private VSAT Networks

	Private VSAT offers "organisational level" connectivity solutions and bandwidths
	Or flexible connectivity where telecommunications and IT are not centralised functions
	Many of the variables and pricing have now been simplified
	More complex networks can be engineered
	Higher bandwidths at lower cost available on demand
	High level business applications can be supported

Example of PolarSat DVB RCS for Broadband IP Networks

International & Internet Connectivity

VSAT connectivity can also provide connectivity outside the organisation, enabling :

	Web browsing & E-mail
	Web applications and server hosting
	VPN connectivity available - including IPSEC
	Multicast services
	VoIP where legally permitted

IT Services

Beyond the basic site-to-site connectivity, the users must make decisions about the level of IT service and support they require. Considerations include :

	Firewalling (where needed)
	Anti-virus updates
	Webmail, POP accounts, or company addressing schemes
	Local LAN cabling
	Power, UPS, and back-up solutions
	Site security for the satellite system and computers
