| The Vipersat Management System (VMS) builds on years of providing our customers with the most advanced automated bandwidth and capacity management system in the industry. VMS is a feature-rich, automated bandwidth, capacity, and network management system with a high degree of configuration automation. It is designed to enable network administrators and satellite service providers to easily configure their networks and rapidly and effectively respond to network anomalies. More than a network monitor and control platform, VMS automates the carrier switching and spectrum management processes within the satellite network. These capabilities allow SCPC carriers to be switched automatically based on application, load, or schedule, providing on-demand services and unparalleled space segment savings. |

Our efficient satellite modem technologies, combined with our VMS, provide dynamic SCPC capacity management solutions. dSCPC facilitates bandwidth sharing resulting in lower space segment operating costs. Efficient, low latency and low jitter SCPC connections can be established, torn down, and dynamically resized manually or automatically. Our Vipersat dSCPC network solutions are comprised of satellite modulators, demodulators, and modems, which are centrally managed and controlled by the Vipersat Management System. VMS is scalable, designed to anticipate and accommodate future growth, and is capable of managing networks of any size.
A variety of Comtech EF Data devices are manageable by the VMS. Different bandwidth saving features and capabilities are supported depending on the device type. The devices manageable by the Vipersat VMS fall into two categories, in-band or out-of-band management. |

In-Band Management
In-Band ManagementVipersat-enabled devices that support in-band management are IP-based modems that have the ability to transmit or receive STDMA burst and automatically request dSCPC circuits from the VMS. The VMS manages and controls these modems “In-Band”, through the same IP interface that user data is carried. The IP capability of In-Band managed modems allow for a wide variety of dSCPC switching methods. |
| |
Out-of-Band Management
Out-of-band managed modems are typically used for point-to-point SCPC circuits that require connections using non-IP G.703, ASI, HSSI, V.35, high speed GiGE interfaces, etc. The VMS has the ability to monitor and control these modems through their 10/100 Base-T M&C interfaces. The management interface is separate from the primary user baseband interface, therefore IP connectivity to the management interface is typically provided “out-of-band” using a separate IP-based connection. |

Dynamic SCPC
VMS is the engine that provides dSCPC bandwidth management of the space segment. When a remote in the network has an application to transport over the satellite link, dSCPC technology provides the mechanism to automatically establish the SCPC carrier for that transmission. dSCPC resizes the carrier based on the increase or decrease in applications being sent over the link, and it returns the remote to its home state once the application is completed. dSCPC yields true bandwidth-on-demand, giving the user the low-latency, low-jitter dedicated SCPC connection when it is needed for real-time applications, such as Voice over IP (VoIP), video conference, broadcasts and large applications (file or image transfers). |

IP-Based Network Control
All management operations and controls are accomplished using standard IP communications protocols. VMS uses a proprietary interface to communicate with the IP-enabled satellite modems that dramatically lowers monitor and control overhead compared to traditional SNMP interfaces. The benefit is less bandwidth required and faster response to control and status messages. |

Demand Mesh Connection
Until now, flexible and dynamic switching systems, such as DAMA or multiple transmission link switches, were bandwidth and equipment resource intensive due to the constraints of traditional, proprietary serial modem interfaces. Switching multiple transmission links via satellite meant reducing flexibility for the benefit of lower latency circuit switches.
Demand Mesh Connection technology offers mesh connectivity based on switching at the application level. Demand Mesh Connection provides significant, dynamic, and rapid connectivity between remotes without suffering the high costs associated with multiple carriers and/or 1-to-1 multi-receiver links. |

Advanced Upstream Site Switching
Traditional shared platforms, such as TDM/TDMA networks, provide a single type modulation/ FEC scheme for their infrastructure. VMS, in conjunction with our highly efficient satellite modems, provides flexibility in setting modulation/FEC rates when establishing SCPC carriers. This allows users to take advantage of both bandwidth-on-demand and higher order modulation/FEC combinations to further optimize satellite links. For example, a remote can be switched out of its home state of QPSK modulation, into 8-PSK or 16-QAM automatically. |

Multi-Transponder Mode (MTM) / Cross-Strap Mode
This MTM function allows unused, fragmented portions of space segment to be allocated across the entire satellite to a network. The allocated space segment can then be used for on-demand SCPC links. Due to the greater bandwidth, MTM only functions with L-band satellite modems.
Cross-strap functionality allows the network implementations on Ku/C, and C/Ku cross-strapped transponders. |
| |
Redundant Configurations
We offer fully automated redundant hardware and software for both hub and remote locations. Our solutions can be placed online without personnel intervention, preserving the link and maintaining transmission of your mission critical data. |
| |
Architecture
VMS is based on a client/server architecture where a central hub communicates with remote nodes in star or mesh topologies. The server maintains all databases in a centralized location accessible to all clients, so updates can be made in a single location and distributed globally to clients. VMS supports centralized management, control and distribution of data, alarms and events. It also supports multiple clients and network management user applications plus access to all system features simultaneously. |
