Teledyne Paradise Datacom Q-NET NMS for Q-Flex Satellite Modems

Q-NET™ Navigator allows all modems (and other network devices) in the system to be controlled through a single application. It provides control over all modem and multi-demodulator functions, using an easy-to-navigate site map, which also displays the real-time alarm status of each modem.

Q-NET™ Bandwidth Manager provides multi-satellite/ transponder carrier planning and high level system control, monitoring, recording and quality-of-service reporting. It runs on standard network server hardware and is accessed via web browser client sessions. It complements the hands-on control provided by Navigator and the two applications can be used separately or in conjunction with each other.

Q-MULTIFLEX 'Hub-in-a-Box'

We refer to the Q-MultiFlex™ as a ‘hub-in-a box’. Why? Because it incorporates all of the following functions in a single 1RU unit that replaces a whole rack of traditional hub equipment:

-Modulator

-Multiple demodulators

-Ethernet managed switch

-Router

-IP bandwidth optimizer

-ACM controller

-Packet encapsulator/decapsulator

-Spectrum analyser

-Oscilloscope (constellation monitor)

-Interference detector

-Traffic generator/analyser

-PRBS BER tester

-Redundancy system controller

And the savings continue to accumulate when you consider the need for fewer spares, less training, fewer interconnect cables, less airconditioned rack space, lower power consumption, etc.

Q-NET™ has redefined the entry-level for satellite network solutions, extending the reach of satellite to a new audience on a tight budget who were previously put off by the high cost and complexity of the solutions available.

Network Topologies

Q-NET™ supports all types of networks. In a star point-to-multipoint network a QMultiFlex ™ generates a shared outbound from the hub to the remotes, which have Q-Flex™ modems for receiving the outbound. They generate return carriers back to the hub, which are demodulated by the Q-MultiFlex™. The box count starts at literally one box at the hub and one at each site for the smallest network. Traffic shaping is typically used to control the content of the shared outbound. VLAN tagging is often used to keep traffic for each site separate.

In a mesh network there is no hub and therefore remote-to-remote comms are all single hop. Each site consists of literally, in the simplest case, a single Q-MultiFlex™. In a full mesh each site transmits an outbound to every site and receives a carrier from every other site.

SCPC versus TDMA

Trying to choose the best technology and the best product is difficult. The industry is littered with competing claims and counter claims.

SCPC and TDMA technologies have their well-known strengths and weaknesses. Some solutions harness both in an effort to present the best of both worlds. However, two lots of hardware equates to two lots of cost! Also, you either have to manage separate pools of bandwidth for TDMA and SCPC or you convert carriers dynamically between TDMA and SCPC. Both introduce further inefficiencies due to the obvious lack of flexibility involved.

The Paradise view is that there is a middle ground where SCPC and TDMA truly compete. By adding innovative, slick SCPC carrier management, allowing intelligent dynamic bandwidth on demand, the bandwidth efficiencies of SCPC can be viably extended to include a significant portion of the traditional TDMA VSAT market.

Q-NET™ has been designed to power next generation satellite communications. One system, boundless connectivity.

How does Q-NET work in practice?

Q-NET™ can be best understood by explaining how to set up a point-to-multipoint network. Using the example of a full mesh:

Each site generates a shared SCPC carrier that is received by all the other sites.

Each site receives an SCPC carrier from every other site. Each Q-MultiFlex™ has an optional modulator and up to 16 demodulators; all use the same FEC for transmit and receive. Q-MultiFlex™ units are cascaded together in order to increase the number of remotes that share the outbound. There is no limit to how large the network can scale.

Each demod is programmed to receive a different centre frequency. The outputs from the inbound carriers are multiplexed together and output to the local network.

Packet management options include bridging (Layer 2) and routing (Layer 3). Typically, VLANs are used to separate traffic for each site and allow the outbound to be partitioned according to the needs of the remote sites. The remote sites filter on the VLANs of interest, untagging the VLAN traffic and passing the traffic on to the local network.

No hub is required and there are no double satellite hops.
