Products with Encryption
NetVue Integrated Management System (NMS)
A state-of-the-art NMS is critical to operating a shared multi-user platform in a cost-effective manner. NetVue is our unified network management platform designed to provide overall network visibility on a single screen, improve resource utilization, improve service quality and Quality of Experience (QoE) to increase customer satisfaction, reduce downtime thereby maximizing service availability. NetVue offers advanced applications for automation, scheduling, monitoring, reporting and spectrum analysis.
The focal point of the Advanced VSAT is our multi-level optimization with the highest spectral efficiency in its class:
Dynamic Bandwidth Management (dSCPC)
The dSCPC capability enables dynamic allocation and sharing of bandwidth among users. Automatic switching modes include load switching and ToS switching. Load switching is ideal for applications, such as ftp and web browsing that can ramp up or down based on available bandwidth. ToS switching is ideal for applications that require fixed bandwidth, such as video conferencing.
Advanced Forward Error Correction (FEC)
The Advanced VSAT incorporates the latest forward error correction technologies:
The combination of DVB-S2 for the outbound and VersaFEC for the return provides maximum spectral efficiency with minimal latency.
Adaptive Coding & Modulation (ACM)
Satellite users have traditionally relied on worst-case link margin to overcome rain fade and other impairments, which leads to significant inefficiencies. ACM converts the available link margin into increased throughput – a gain of 100% or more is possible. With the ability to maximize throughput under all conditions – rain fade, inclined orbit satellite operation, interference and other impairments – ACM allows each remote to achieve maximum throughput thereby maximizing network efficiency and availability. ACM operation is integrated with advanced QoS and other optimization technologies to maintain desired service levels.
RAN Optimization significantly reduces the satellite bandwidth required for mobile backhaul. The Advanced VSAT’s RAN optimization capabilities allow users to select the level of RAN optimization to achieve the desired link quality and bandwidth savings, providing ultimate control. And, the pre-emptive bandwidth management maintains superior voice and service quality even under WAN congestion conditions.
High-Performance Packet Processing
For efficient IP networking and transport over satellite, the product features high-performance packet processing capability with very low overhead encapsulation, header compression, lossless payload compression and multi-level QoS that is fully integrated with ACM and Dynamic SCPC.
- Header Compression
- Lossless Payload Compression

Multi-Service Connectivity via Advanced VSAT Solutions
Seamless Layer 2 or Layer 3 Operation
The Bridge Point-to-Multipoint (BPM) capability enables true layer 2 operation so that an Advanced VSAT network operates like an Ethernet switch in the sky with MAC learning, VLAN trunking and VLAN access mode while benefitting from:
- Multi-level QoS, allowing classification by VLAN ID
- Header compression including Layer 2, Layer 3 and Layer 4 headers
- Lossless payload compression
- Bi-directional Adaptive Coding & Modulation
- Dynamic SCPC bandwidth on-demand
Ethernet frames containing higher layer protocols including VLAN, MPLS, IPv4/IPv6, UDP, TCP, RTP, OSPF and BGP, seamlessly flow through an Advanced VSAT network just like any Ethernet switch, greatly simplifying the network design, deployment and operation and enabling seamless integration with existing IT infrastructure. BPM mode also allows seamless transport of MPLS over Ethernet. With ever-increasing transmission speeds and usage of VLANs and MPLS, the need for larger and larger Ethernet frames for improved efficiency continues to grow. Advanced VSAT BPM mode supports jumbo Ethernet frames up to 2018 bytes.
Advanced VSAT supports global roaming in conjunction with the Vipersat Management System and Roaming Oceanic Satellite Server (ROSS). This allows a remote satellite terminal on-board an oceanic vessel to seamlessly transition between satellite beams or hub coverage with minimal service interruption. ROSS functions as the onboad mobility controller – interfacing to the Antenna Control Unit (ACU), maintaining satellite footprint maps, shoreline contour vector maps and exclusion zones, and initiating beam switching and handoff as the vessel moves through satellite footprints. The ROAM protocol offers a common management interface for the ROSS and the ACU by providing a common set of commands, information, interfaces and status queries.
Seamless E1 and IP/Ethernet Operationn
The Advanced VSAT enables simultaneous E1 and IP/Ethernet operation in a hub-spoke topology, while supporting advanced capabilities including RAN optimization, header compression, lossless payload compression, QoS and ACM. In addition to supporting multiservice networks, this allows for seamless migration from an E1 RAN to an all IP RAN.
WAN Optimization and Application Acceleration
WAN optimization and application acceleration provide TCP connection management, TCP optimization, image reduction and smoothing, caching, bandwidth pooling, and other capabilities. In addition to a significant improvement in user experience, they can also reduce bandwidth by 20-70% for web traffic.
The Advanced VSAT provides a highly scalable and cost-effective solution to meet the needs of a diverse user community. A network can start with a few sites and expand to hundreds of sites. The bandwidth can also scale as needed – the outbound can scale from as low as 1 Mbps to as high as 160 Mbps. The return can scale from as low as 16 kbps to as high as 15.35 Mbps.
