JUPITER System with DVB-S2X PerformancePrevious Next
Next-generation, high-throughput platform for satellite broadband networks.
The Hughes JUPITER system is a high performance and high efficiency satellite broadband platform designed to support a wide range of applications across all market sectors, from consumer to enterprise, government and mobility. Powering the world's largest satellite broadband service HughesNet in North America, the JUPITER system has been deployed by leading operators around the world, on both High-Throughput Satellites, making it the preferred technology choice for delivering advanced broadband services.
Powered by the JUPITER System on a Chip (SOC), a powerful multicore ASIC, every HT2000 terminal is also able to achieve more than 100 Mbps of throughput. This throughput enables the JUPITER system to be effectively used for a wide variety of applications and markets.
- Broadband Internet access
- Enterprise networking
- Cellular backhaul
- MPLS extension
- Video conferencing
- Community Wi-Fi Hotspots
Traffic management and Quality of Service (QoS) are achieved through integrated traffic classification with five traffic priorities (based on the 3GPP standard); intelligent, protocol-sensitive bandwidth assignment for optimum performance using a variety of bandwidth assignment schemes including Committed Information Rate (CIR), on-demand Committed Bit Rate (CBR), Adaptive CBR (outbound and inbound) and backlog-based assignment.
First in the industry with the DVB-S2X wideband forward channel, the JUPITER system can operate a single carrier in a 250 MHz channel. DVB-S2X brings more MOD/COD points, which enable operation closer to the theoretical Shannon curve as compared to DVB-S2. A 5% channel roll-off further improves efficiency. Higher order modulation (16APSK and 32APSK) is available at the highest symbol rates.
The JUPITER system TDMA return channels deliver the industry's best efficiency thanks to the LDPC return channel coding and the Aloha-based contention scheme, which enables idle remote terminals to deallocate all return channel capacity. With support for the return channel throughput.
Powerful IP Features
Designed to support demanding enterprise applications, the Jupiter system supports a full a full range of IP routing protocols including BGP IPv4, BGP IPv6, and RIP v2. Duel stack IPv4 and IPv6 means that both protocols can be supported simultaneously. VLAN with DSCP-based prioritization enables effective portioning of traffic off the remote site. Support for Virtual Router Redundancy Protocol (VRRP) along with policy-based routing enables remotes to effectively and seamlessly interface with terrestrial routers to provide alternate path selection as well as load balancing over satellite and terrestrial links.
Advanced Acceleration Features
Integrated into the JUPITER system is a comprehensive set of acceleration and compression algorithms that drive performance and efficiency. The Hughes proprietary Performance Enhancement Proxy (PEP) provides for TCP spoofing. ACK reduction and flow control to accelerate TCP traffic over the satellite link. In addition, Web acceleration where HTTP objects are pre-fetched by a proxy server at the gateway, pushed over the satellite link and cached in the remote terminal, delivers near terrestrial like screen paints for an industry-best surfing experience. The Web acceleration incorporates an advanced grammar-based compression algorithm that can significantly reduce overall HTTP traffic. Integrated DNS caching in the remote terminals eliminates satellite latency introduced by DNS lookup Queries.
JUPITER Systems HT Remote Terminals
The JUPITER system gateway is integrated with the powerful and full-featured NMS. The NMS platform provides a single, intuitive, easy-to-use Graphical User Interface (GUI) and advanced diagnostic capabilities through which operators can easily manage and monitor multiple networks on multiple satellites. The NMS GUI provides detailed graphical views of both real-time status and historical performance of all gateway components and managed terminals. The NMS is available in different configurations including a single gateway NMS configuration as well as a large-scale multi-gateway configuration with a manager of managers.
An extensive and powerful restful Application Programming Interface (API) enables easy integration with an existing OSS/BSS. The API enables an external system to perform virtually any operation that can be performed through the NMS GUI.
The NMS includes a fully automated provisioning and remote terminal commissioning system, Remote terminals can be provisioned in bulk electronically or manually via the GUI. The commissioning process is performed without any manual intervention at the gateway or NMS. An optional automatic cross-polarization test process can be used to confirm proper operation of the remote terminal.
The NMS includes an integrated set of Host Network Operator (HNO) and Virtual Network Operator (VNO) capabilities. The HNO/VNO capabilities enable an HNO to establish and operate multiple independent VNOs, each of whom can be provided with a logical partition of the network resources including bandwidth. VNOs can be weighed relative to one another to enable high value VNOs to be provided resources at a higher rate relative to lower value VNOs.
JUPITER System HT Remote Terminal
At the heart of every JUPITER system HT2000 remote terminal is the advanced JUPITER SoC, a powerful multicore ASIC. The JUPITER SoC enables the HT terminal to achieve up to 200 Mbps of throughput. In addition to the throughput performance, the HT2000 has a powerful IP routing feature set so the terminal can be used for virtually and application.
The HT2000 series includes the following:
- Operates in either Ku-band or Ka-band
- Equipped with a single GigE LAN port
- Supports a single cable IFL for interface to the Outdoor Unit (ODU)
- Well Suited for home or small-office applications
