    User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing 2.1.2 IP Bridging in the Satellite Subnet 2.1.2.1 Introduction IP bridging is more efficient than Ethernet bridging. IP bridging has the following advantages: • It reduces the overhead on the satellite link: the Ethernet link is terminated in the same way as a router does.
  • Page 31 User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing 2.1.2.2 Router Configuration: The router is configured with the full satellite subnet (e.g. a /24 subnet), and not the limited local subnet. The next-hop IP address for the local router is the remote router, and not the local modem (the local modem acts like a bridge).
  • Page 32 User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing On a modem (or modulator, or demodulator) the satellite subnet is split into different IP ranges, while this partitioning is not known to the routers and the PCs inside the satellite subnet.
  • Page 33 User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing 2.1.2.8 Directly attached Host Configuration: The routers as well as the PCs that are drawn inside the satellite subnet don't need to know that the satellite subnet is split into different IP ranges. The subnet of the routers and the directly attached IP hosts must be equal to the full satellite subnet (10.0.0.x/24)!

  • Page 34: Ip Routing

    User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing 2.1.3 IP Routing 2.1.3.1 Introduction The satellite modems can act as a normal router: the satellite modem or modulator will then be configured as the next HOP of the attached router(s). In such a case there is no need to perform proxy ARP for remote IP addresses (the remote subnet is configured to 0.0.0.0/0).
  • Page 35 User Manual for EL170/970/470 IP Satellite Modulator/ Network Models and Traffic Demodulator/Modem Routing 2.1.3.3 Modem Configuration The modem configuration is almost identical to the configuration for an IP bridge: only the remote subnet of the IP interface is set to 0.0.0.0/0. This means that the device will not perform proxy ARP for the remote IP addresses.

VLANs are virtual Ethernet links on top of 1 physical Ethernet link.
  • Page 37 VLAN enabled routers often support the concept of VRFs (Virtual Router Functions). Each VRF has its own routing table. On the Newtec modem/modulator/demodulator, each VLAN belongs to a different VRF, so this means that each VLAN has its own routing table.

  • Page 169 User Manual for EL170/970/470 IP Satellite Modulator/ Features Demodulator/Modem 9.13.2.4 Use of Group Key The group key can be used in two ways: • A unique group key is defined for each device. In that case, a different encrypted content key needs to be sent to each device. This key is unique and the operator is guaranteed that if the key is intercepted, it cannot be used on another device (unless the group key is known).
  • Page 170 On most Newtec devices, a total of four pairs of odd and even content keys or pairs of odd and even encrypted content keys can be linked to the ISI-values of the streams that need to be encrypted.
