OverviewThe problem is familiar. Service providers want to share bandwidth effectively and ensure links are highly efficient. Historically, this has required choosing between TDMA and SCPC solutions. Now, for the first time, Q-NET™, an open, innovative, scalable, fully-featured satellite resource management system, resolves this age-old dilemma. It does this by using new technology that combines unparalleled bandwidth-efficiency with flexible carrier management, giving the best of both worlds.
Q-NET™ provides Multiple Channel Per Carrier (MCPC) Demand Assigned Multiple Access (DAMA). When coupled with the best-in-class bandwidth efficiency of the Q-Flex™ satellite modem, Q-NET™ delivers the highly variable throughput services that constantly changing traffic patterns demands. The Q-Flex™ modem embodies a new concept in satellite modem technology - a flexible software-defined modem based on a universal hardware platform that does what you want, now and in the future.
As well as bandwidth management, Q-NET™ provides full network infrastructure management or all resources and services, including system performance monitoring and both real-time and historical data analysis.

Q-NET™ Bandwidth Manager
Satellite resources are allocated from a centrally managed pool, allowing bandwidth to be shared amongst all users. Bandwidth can be allocated manually, scheduled at defined times or allocated dynamically based on current demand.
For star networks, an MCPC shared-outbound carrier is transmitted from the hub to all remote sites. Contention for bandwidth is managed with minimal control overhead, resulting in the highest bandwidth efficiency in the industry.
Dynamic bandwidth management is provided via flexible, automated carrier switching that supports a wide variety of bandwidth sharing policies. As well as controlling bandwidth allocation between sites, sophisticated control over individual traffic streams within the overall traffic stream is supported. All common quality of service mechanisms are supported including DSCP, MPLS, IEEE 802.1p, etc. Q-NET™ includes the ability to manage and monitor both ground-segment and transponder power usage.
Q-NET™ Resource & Service Management
Q-NET™ supports the management of all network infrastructure resources and services.
A graphical Topology Editor, together with resource and service managers, allows administrators to quickly create and edit system resources, services, relationships and roles. Dashboards provide system-wide information on resources, services, alarms and operator notifications. Dashboards can be customised for each type of user in order to present only the information that is required and can be used to automate workflows such as link deployments.
Q-NET™ Traffic Analyzer
The Traffic Analyser allows real time and historical analysis of network performance. Using SNMP, performance data is automatically gathered from the terminals in the system and is stored in a central database. The data can be viewed graphically over a desired time period. Different performance data can be viewed together in order to identify trends and synchronous events. Traffic analysis allows viewing traffic by protocol, source, destination, time, transmit, receive, dropped packets and errored packets.
In addition to terminal performance data, the Traffic Analyser collates and maintains a set of performance data on the network itself. This includes precise bandwidth allocation and usage metrics allowing the overall effectiveness of the network to be readily identified. Distinctive coloring on the graphs alerts the operator to problem hot-spots such as link failures. Alarms can be easily cross-correlated with configuration changes, a common source of unexpected system problems.
The Traffic Analyser is designed to allow operators to quickly become familiar with traffic patterns in the network to support better capacity and operational planning.
Q-NET™ Report Generator
The Report Generator allows the easy generation of system performance reports. The Report Generator allows any view of the network metrics to be exported as a PDF, PPT, spreadsheet or plain text document. The output can be integrated directly into quality reports and other documentation.
The Report Generator supports the generation of typical quality of service metrics commonly found in Service Level Agreements (such as availability, jitter, latency, packet loss and throughput). Standardised and customised pie, line and bar charts can be generated along with cross-tabulated matrices and filtered summary performance reports, either on demand or periodically.
