Basic IP Network Topologies

®
The basic IP network topology of a fully meshed SkyWAN network is displayed in figure 4-3.

Figure 4-3 SkyWAN Meshed IP Data and Management Network
®
Each SkyWAN IDU is connected via its Ethernet interface(s) to a local LAN IP network. On
the satellite side each station is connected via its Sat-UTx interface(s) to a Core IP network.
®
Additionally each SkyWAN IDU is connected via its Sat-MT interface to a common Manage-
ment IP network. This management network is used to perform remote management of the en-
tire network via satellite, using a SkyNMS PC which can be connected to the LAN(-MT)
interface of any station. This management network is defined on the master station. Note, that
it must not overlap with any user IP subnetwork, including networks which are not directly con-
®
nected to the SkyWAN stations but can be reached via external routers.
The IP subnetwork structure for a hybrid network is represented in figure 4-4. This hybrid net-
work is consisting of a meshed core (stations A-D) plus two star networks for which stations C
and D provide the traffic hub functionality.
