Built on a solid foundation of IP features and functionality, the HN/HX systems are the solutions for satellite routing where full IP functionality is required together with performance. The HN/HX systems provide advanced bandwidth management capabilities, which give operators the ability to custom design various Quality of Service (QoS) and Service Level Agreements (SLAs) on a per-remote basis. As pure IP-based solutions, the HN/HX systems incorporate a strong set of IP functions and features.

IP Protocols

Every HN and HX remote terminal incorporates a full set of unicast and multicast IP protocols, including TCP and UDP and the protocols carried on top of them (HTTP, SSL, RTP, SIP, etc.). The routers also support other IP protocols such as ICMP, IGMPv3, and other commonly required protocols.

Routing Protocols

The HN/HX systems enable network interoperability through a wide range of routing protocols, including RIPv2, BGP4, ICMP, and ARP. Each HN/HX terminal can be configured using Policy- Based Routing (PBR) to provide the network connectivity and performance demanded by the user. Features such as VRRP (Virtual Router Redundancy Protocol) allow seamless support for alternate path routing and VLAN tagging provides effective support for management of multiple subnetworks on a common LAN.

IP Services

The HN and HX routers provide IP services that benefit both enterprise and consumer applications such as flexible addressing with support for Network Address Translation (NAT) and Port Address Translation (PAT). The capability of the HN and HX routers to act as either Dynamic Host Configuration Protocol (DHCP) servers or DHCP relays provides higher performance. Integrated support for Access Control Lists (ACLs) and firewall services further enhances the features and functionality of the HN/HX solutions.

Performance Features

To minimize the effects of satellite latency, the HN/HX systems offer a range of integrated acceleration and QoS features. These features, including prioritization of the IP traffic based on Terms of Service (TOS) or Differentiated Services Code Points (DSCP) values, together with Policy Based Routing rules, provide an easy way to achieve Weighted Fair Queuing for enterprise applications. Integrated TurboPage® is available to provide HTTP acceleration by applying pre-fetch of objects.

Network Security

User security is a key feature of both the HN and HX systems that is achieved through multiple levels of security. At the transmission level, the HN/HX systems employ DES encryption of the DVB-S2/ACM outbound channel. Integrated with the outbound DES encryption is a conditional access system that ensures that the right router gets the right data and prevents unauthorized “eavesdropping.” At the IP level, the HN/HX systems have the option to provide bi-directional IPSec encryption using the Internet Key Exchange (IKE) protocol for dynamic session keying. With the IPSec option, the HN/HX systems are fully FIPS 140-2 certified.
