HN9400 Broadband Satellite Router |
Ka/Ku-band high throughput satellite router with Advanced Adaptive LDPC Coding
The Hughes HN9400 is a Ka/Ku-band broadband satellite router designed to support High Throughput Satellite (HTS) applications. With a full set of IP features, the HN9400 is a powerful router for a wide range of applications from high-end enterprise applications to the most demanding consumer applications.
 The HN9400 is capable of processing up to 60 Mbps of multicast traffic and up to 15 Mbps of TCP traffic in the forward direction. The FDMA/TDMA return channel is powered by Adaptive LDPC Coding developed by Hughes, which enables the highest return channel performance and efficiency in the satellite industry.
High Throughput, High Efficiency and Full Featured
The HN9400 is a powerful satellite router featuring high performance on both the DVB-S2/ACM forward channel as well as the Adaptive LDPC Coding return channel. Using LDPC Coding for the return channel provides significant error coding improvement over Turbocode, thereby enabling very efficient use of satellite capacity. The Adaptive Coding of the return channel enables the unit to dynamically change FEC rates, burst-to-burst, based on link conditions to achieve the highest throughput while maintaining high link availability. Through the combination of Adaptive LDPC Coding and a powerful processor, the HN9400 supports upstream burst rates of 3.2 Mbps, making the HN9400 an ideal platform for the next generation satellite broadband systems.
To enable superior end-user performance, the HN9400 includes a full set of integrated Wide Area Network (WAN) optimization features. Accelerated TCP and HTTP performance, including HTTP pre-fetch (objects are locally cached on the HN9400) along with DNS caching, enables fast Web surfing. Integrated header and packet payload compression both conserves bandwidth and contributes further to high performance.
A full-featured IP router, the HN9400 supports a switching capacity up to 5,000 packets per second eliminating the need for an external router. IP routing and addressing features implemented in the HN9400 include the RIPV2 and BGP routing protocols, virtual router redundancy protocol (VRRP) with policy-based routing, DHCP server or relay, as well as network address translation (NAT) and port address translation (PAT). The HN9400 also handles end-to-end VLAN tags complying with the 802.1P and Q standards and each VLAN may be configured with its own quality of service (QOS). Government and enterprise users can be confident of the security of information running over the HN9400 security, as it uses a hardware-based conditional access system and optionally AES 256 encryption for user traffic.
Network operations are easy to perform as the HN9400 features an integrated Web server supporting a Web browser interface for commissioning and troubleshooting. Full-featured, built-in diagnostics provide historical information about network performance or error conditions. An integrated LAN sniffer eliminates the need for on-site presence during trouble-shooting. The HN9400 is centrally managed for software configurations and downloads.
Adaptive LDPC Coding
The HN9400 incorporates the Hughes developed, innovative Adaptive LDPC Coding on the return channel, enabling superior modem performance. The Adaptive LDPC’s ability to run with minimal link margin enables the maximum bandwidth efficiency. Additionally, the HN9400’s use of variable burst and associated LDPC code block lengths sized to precisely fit the exact amount of IP data to be transmitted, further increases the return channel efficiency. Overall, the Adaptive LDPC Coding of the return channel enables more than 20% bandwidth efficiency improvement over competing systems.
