On Demand Services:
Intelsat General’s OnDemand Service consists of a large outbound digital video broadcast (DVB) data carrier and single channel per carrier (SCPC) return channels. The service is capable of handling any type of IP protocol traffic, i.e. data, voice, and video. OnDemand can provide quality of service (QOS) function necessary to assure the performance of time-sensitive applications like voice-over-IP (VoIP) circuits. The service is currently operational on G-10R and Horizons-1 and provides 50-state coverage. OnDemand is controlled and monitored using the Vipersat Hub at Intelsat General’s Ellenwood, GA, facility. The Service can be used with a wide range of VSATs equipped with a Comtech Vipersat-enabled modem.
On Demand Service Options:
The primary architecture associated with this service is hub-star with all remote sites communicating with the Ellenwood hub. From Ellenwood the remote sites can be: 1) connected directly to the Internet backbone, 2) connected to a designated location using a dedicated fiber or copper link, or 3) connected to a designated location using a secure/encrypted virtual private network (VPN) connection through the Internet.
Vipersat can also support mesh communications, wherein remote sites can additionally communicate with each other. The service is also capable of supporting a remote hub-star private network. In this configuration a customer could establish his own hub-star architecture for his remote sites with the control of his network supported by Ellenwood.
1) Dedicated DVB x Dedicated SCPC: Provides a dedicated DVB circuit on the outbound carrier and an SCPC return circuit from the remote site(s). This would be a private network with dedicated capacity.
2) Dedicated DVB x per min. SCPC: Provides a dedicated DVB circuit on the outbound carrier and an SCPC return circuit from the remote site(s). However, rather than a full-time SCPC return channel, this return channel is available using the per minute rate card. Operationally this service will be implemented by programming the remote site terminal to recognize the bandwidth requirements for specific remote site applications, e.g. browsing, video, voice, etc. When these applications are operating, SCPC circuits will be "nailed up" on an ad hoc basis to support the traffic. The outbound, dedicated circuit will be billed on a fixed monthly rate. The return channel will be billed based on utilization at the per minute rates. This service is particularly applicable to remote sites with infrequent communications and a need to support applications with a wide-range of bandwidth demands such as voice and video.
3) Shared DVB x per min. SCPC: Provides a bursting information rate (BIR) on the DVB outbound carrier. The per minute return channel operates in the same fashion as the description, above. Service on both the inbound and outbound circuits is "best effort" and subject to availability. This is an "always on" service, and is ideal for very rapid response. With a self-erect/self-align antenna this service can be activate anywhere and at any time.
