Comtech EF Data H-Pro ODU Heights Remote Gateway
Comtech EF Data H-Pro ODU Heights Remote Gateway
The Heights™ Networking Platform is engineered to elevate your services with unparalleled horsepower, efficiency and intelligence. The Heights platform was designed with the service provider and its multi-user environments in mind, from concept to operation.
Heights combines our most efficient waveforms, header and payload compression engines, WAN GTP data optimization, proven dynamic bandwidth and power management and bidirectional ACM capability fully integrated with multi-tier Quality of Service (QoS) to provide the highest user Quality of Experience (QoE), highest user throughput, highest availability, and most optimal resource utilization available in the industry.
Heights meets the demands of those operating on traditional wide beams while providing distinct advantages for those using or planning to use High Throughput Satellites (HTS) in future. Heights is HTS ready, allowing service providers to leverage the significant increases in throughput from the new HTS designs.
Purpose-built to unleash the potential of these tight spot beams, Heights remote gateways provide the strongest processing performance, maximizing user IP bits per Hz while realizing significant gains in user IP bits per Amplifier (BUC) Watt.
The H-Pro Remote Gateway is the high-performance platform capable of delivering unprecedented throughput to remote sites in a shared bandwidth environment. It supports multiple transmit throughput tiers up to 197.5 Mbps, managed via centralized licensing capability for ease of use, allowing users to standardize on a single remote platform, simplifying stocking and sparing.
Heights Dynamic Network Access (H-DNA)
H-DNA is an evolutionary dynamic network access technology designed for Heights return links that:
- Rapidly adapts to changing environments
- Delivers superior efficiency & Quality of Experience (QoE)
- Instantly assigns capacity based on network-wide demand
- Intelligently utilizes total network bandwidth at all times
H-DNA is designed to provide network wide fast switching on a sub-second interval making the process seamless and transparent to end users for real-time as well as non real-time applications. H-DNA leverages Comtech’s high performance VersaFEC-2 waveforms with ACM, dynamic power control, high performance packet processing, network wide multi-tier QoS and IP optimization technology to enable unprecedented bandwidth efficiency and superior QoE. H-DNA fast switching and bandwidth allocation mechanism allows a Heights network to respond rapidly to changing traffic and link conditions while maintaining lowest latency and jitter for superior QoE and maximum bandwidth utilization efficiency.
H-DNA is fast, flexible and uncompromising, delivering unprecedented benefits to users and service providers alike. More detail is available on: http://www.comtechefdata.com/technologies/heights-dynamic-network-access-h-dna

Unparalleled Remote Horsepower
H-Pro incorporates unprecedented processing power enabling high throughput with multi-layer optimization. The increased EIRP and G/T performance of new HTS spacecraft allows for significantly higher throughput. However, this increased throughput cannot be met if the underlying packet processing is not able to keep up with the increased traffic flow. The quad-core processor in H-Pro can support the most demanding user applications in a HTS environment enabling service providers to take full advantage of the potential of these new HTS designs and grow service levels as end users’ demands grow.
Seamless Bridge Point-to-Multipoint (BPM) Mode or Routed Mode
In addition to routed mode, the Heights Networking Platform supports BPM mode for true layer 2 operation enabling seamless integration with service provider network. A Heights network operating in BPM mode can be viewed as an Ethernet switch supporting VLAN and MPLS while benefiting from bi-directional IP optimization, multi-tier QoS, ACM and dynamic bandwidth management. H-Pro includes extensive VLAN support including VLAN Access mode, trunk mode and QinQ. In BPM mode, H-Pro supports traffic classification and QoS by VLAN ID as well as MPLS Traffic Class Field (formerly referred to as EXP bits).
WAN Optimization and GPRS Tunneling Protocol (GTP) Mobile User Data Traffic Optimization
Heights Remote Gateways incorporate embedded WAN optimization for Internet Traffic and GTP traffic Optimization. GTP is used in mobile networks on 3G IuPS, 3G IuH and LTE S1 interfaces. Mobile subscriber traffic is encapsulated within an IP/UDP/GTP tunnel. Embedded GTP traffic optimization allows for optimization of the mobile subscriber traffic within the GTP tunnel, improving user Quality of Experience (QoE) through greater throughput and faster response time, and rendering the Mobile Network more efficient.
Heights WAN and GTP optimization provide TCP acceleration, based on Comtech’s patented TurboStream Performance Enhancement Protocol (PEP). TurboStream mitigates TCP performance issues across long delay links through intelligent implementations of scalable WAN TCP windows, and traffic multiplexing of LAN TCP sessions into persistent WAN TCP sessions. This process greatly reduces “time to first byte”, which means that the traffic starts flowing much faster than it would otherwise, and also enables traffic to ramp up to levels which would not be otherwise possible over long latency VSAT links.
Heights WAN and GTP optimization incorporate remote DNS caching enabling remote users’ web browsers to quickly resolve Host names to IP addresses locally, once again speeding up the “time to first byte”. Without local DNS caching, all DNS inquiries would have to traverse the VSAT link leading to longer delays before traffic starts actually flowing.
Heights WAN and GTP optimization also support image smoothing, thereby reducing the amount of data that needs to traverse the satellite link. Image smoothing also speeds up the time to download the webpages.
WAN and GTP optimization requires the FX Series at the hub. WAN optimization and GTP optimization is fully integrated with network wide multi-tier QoS, ACM and IP optimization for maximum performance and efficiency.
Global IP Roaming
An embedded mobility controller in H-Pro enables a satellite terminal on-board a mobile platform to seamlessly transition between satellite beams or hub coverage with minimal service interruption. The embedded mobility controller interfaces with the Antenna Control Unit (ACU), maintains satellite footprint maps and initiates beam switching and handoff as the vessel moves through the satellite footprint. It offers a common management interface for the mobility server and the ACU by providing a set of commands, information, interfaces and status queries.
Heights supports dynamic remote-to-remote connections (MESH) in router mode with Dynamic SCPC (dSCPC), using additional receivers at the remote. Dynamic MESH requires “loop-back” operation where each site in a MESH connection is able to receive from all other sites in that MESH connection. Dynamic MESH eliminates double hop latency as remote-to-remote packets don’t have to transit through the hub. It also requires 50% less bandwidth as a remote-to-remote double hop link would consume almost twice the bandwidth.
