Page 118: Chapter 7 Q-Net™ Implementation
QMultiFlex-400™ Installation and Operating Handbook Chapter 7 Q-NET™ Implementation This section shows some topologies used with Q-NET™ networks and includes some information to help implement a Q-NET™ system. The Q-NET™ satellite network solution is a highly flexible and scalable satellite network solution designed for a broad range of markets, applications and business models.
Page 119: Network Topologies
Point-to-Multipoint Star Network A star network topology is shown in Figure 7-1. In this scenario, a QMultiFlex-400™ generates a shared outbound from the hub to the remotes, which have QFlex-400™ modems for receiving the outbound. They generate return carriers back to the hub, which are demodulated by the QMultiFlex-400™. The box count starts at literally one box at the hub and one at each site for the smallest network.
Page 120: Mesh Network
A mesh network topology is shown in Figure 7-2. In a mesh network there is no hub and therefore remote-to-remote communications are all single hop. In the simplest case each site has a single QMultiFlex-400™. In a full mesh each site transmits an outbound to every site and receives a carrier from every other site.
Page 121: Point-To-Point Network
QMultiFlex-400™ Installation and Operating Handbook 7.1.3 Point-to-point Network A point-to-point network topology is shown in Figure 7-3. This type of network consists of a series of individual point-to-point links between QFlex-400™ modems. As well as dedicated point-to-point networks, point-to-point links are often used for occasional-use links in larger point-to-multipoint networks or to address parts of the network that require limited connectivity.
Page 122: Tcp/Ip Traffic Management
Figure 7-4 shows the most basic configuration used for a point-to-multipoint bridging solution. Ethernet switches can be deployed, as required, between the satellite devices (QMultiFlex-400™, QFlex-400™) and the user network (the user network being any combination of switches, routers and end-user devices). In this scenario, a single subnet is used for the satellite modem network.
Page 123: Point-To-Multipoint Routing
7.2.2 Point-to-Multipoint Routing In routing mode, the QMultiFlex-400™ and QFlex-400™ modems act as two-port routers, with the terrestrial IP port being on one subnet and the satellite port being on another subnet.

QMultiFlex-400™ Installation and Operating Handbook 7.3 Cascading Multiple QMultiFlex-400™ Units Multiple QMultiFlex-400™ units can be cascaded together in order to address an arbitrarily large number of remote modems with a single outbound carrier. There are two methods that can be used to cascade units together. The first involves cascading units directly together and involves no external equipment.

QMultiFlex-400™ Installation and Operating Handbook 7.5 Remote Modem M&C It is not recommended to use the M&C bridge to bridge M&C and IP traffic together as typically there are separate VLANS involved using different networks. Bridging the M&C and traffic together limits the unit to one network, which is not typically what is desired with a point to multipoint network.
Page 130: Multiple Streams And Traffic Shaping
QMultiFlex-400™ Installation and Operating Handbook 7.6 Multiple Streams and Traffic Shaping Single stream mode allows a single MODCOD to be applied to the shared outbound carrier, whereas with multiple streams, potentially different MODCODs can be applied to the individual streams when they are transmitted over satellite in the shared outbound carrier (a feature known as Variable Coding and Modulation (VCM)).
Page 131 QMultiFlex-400™ Installation and Operating Handbook stream) in the shared outbound with varying link conditions as experienced by each remote modem. ACM therefore converts any unused link margin (on a per-site basis) into additional throughput. ACM also provides 100% link availability by allowing the use, during heavy rain fades, of MODCODs with very high error-correcting ability (down to QPSK ¼).
Page 132: Chapter 8 System Considerations
QMultiFlex-400™ Installation and Operating Handbook Chapter 8 System Considerations 8.1 Automatic Uplink Power Control Authorisation from the satellite operator should be sought before AUPC is activated. 8.1.1 Introduction Automatic Uplink Power Control (AUPC) provides a mechanism to counteract changes in atmospheric conditions, such as rain or snow, that degrade the performance of satellite links.
Page 133: Adaptive Coding & Modulation (Acm)
The web user interface remote Eb/No and power graphs can be used to review AUPC performance. Note: AUPC is limited to a single QMultiFlex-400™ unit i.e. up to 16 remotes. Cascaded units are not currently supported. There are other limitations with this feature in a Point to Multipoint system.
Page 134 The receive side is degraded, hopefully within a rain fade margin. ACM & VCM (Bidirectional ACM) Multiple Tx Streams can be configured in the QMultiFlex-400™ with the remote demod matching the MODCOD for each stream. Applying ACM will make the VCM links even more robust, with each individual stream changing to adapt to environmental conditions.
Page 135: Configuring Acm
QMultiFlex-400™ Installation and Operating Handbook Degradation position 2: Hub individual stream MODCOD changes and reduces throughput as necessary to maintain link (other streams stay the same). The remote transmit adjusts MODCOD to keep the respective demodulator in lock. Note: VCM can be used in the one-way outbound mode, but for maximum robustness the bi-directional ACM would be typical in a multiple stream scenario.

8.3.6.7 Hub Canceller vs No. of Rx channels All QMultiFlex-400™ hub modems are fitted with hardware to support: A) 14 Rx channels with a hub-canceller enabled or B) 16 Rx channels (an extra two Rx channels) without the hub-canceller being enabled.
Page 156: 1:1 Redundancy Operation
QMultiFlex-400™ Installation and Operating Handbook This allows the network to grow simply by acquiring the SAF options (licences) to get more channels rather than to purchase and install extra hardware. Logic resources are required to implement the cancellor function. The amount of logic resource to implement the canceller is the equivalent of just under two demodulators, hence, if the canceller is not being used, those logic resources can be assigned to implement two more Rx channels.

QMultiFlex-400™ Installation and Operating Handbook 8.7.8.1 Guaranteed Bandwidth The allocation of bandwidth to a classified data stream can be controlled. The Committed Information Rate (CIR) is the guaranteed bandwidth that will be allocated to the specified data stream. This is the level of bandwidth that is guaranteed under all normal circumstances where the equipment is operating correctly.
Page 171 QMultiFlex-400™ Installation and Operating Handbook • The source and/or the destination address in the IP packet along with the source and/or the destination port number of the TCP or UDP header in the packet. Any or all of these can be used in any combination at the same time, including using a range of port numbers.
Page 172 Data stream classification can be based on VLAN ID, which need to be added externally to the QMultiFlex-400™ - usually in the form of an IEEE 802.1q trunk. The example in Figure 8-29 shows a set of traffic shaping rules based on VLAN ID.
Page 173 QMultiFlex-400™ Installation and Operating Handbook Figure 8-29 Traffic Shaping using VLAN ID In this example, three VLANs (10, 20 and 30) are all guaranteed 33% each of the available bandwidth but none of them are allowed to exceed this. Each has the same priority, which should ensure that all of these VLANs experience similar levels of jitter.
Page 174 QMultiFlex-400™ Installation and Operating Handbook In this example, the Expedited Forwarding (EF) class is given the highest priority (0) and is guaranteed 10% of the available bandwidth. Two Assured Forwarding classes (3 and 4) are guaranteed 10% of the available bandwidth for each drop probability (1, 2 and 3). Each AF class is given the appropriate level of priority corresponding to its precedence and drop probability.
Page 175: Traffic Shaping Graphs
QMultiFlex-400™ Installation and Operating Handbook shows the modem queuing priority level. Although there is a straightforward one-to-one priority mapping between IEEE 802.1p priorities and those of the modem, explicit control of this allows priorities to be changed if required. The default class (Def), allows bandwidth to be explicitly reserved for traffic that does not have an IEEE 802.1Q header attached.

VLAN30 Figure 8-32 Internet Distribution to Three Remotes (Star) The QMultiFlex-400™ is connected to the hub router with a VLAN trunk. The hub router provides DHCP information to the remote PCs (IP, gateway and DNS addresses) and uses PAT overload to connect them to the ISP office router.

12.2 FEC BER/PER Performance Teledyne Paradise Datacom has standardised on QEF tables rather than BER curves. This reflects the fact that DVBS2 & DVBS2X has very steep curves, which makes operating at a certain point almost impossible. Therefore, the difference between the performance stated in this section and true QEF points (where there are effectively no errors) can be as little as 0.1 or 0.2dB.
