20. Mesh VSATs
Mesh topology configurations enable direct VSAT-to-VSAT connectivity using a single satellite hop.
The main advantage of mesh compared to star operation is the low latency for real-time traffic and
reduced satellite bandwidth usage.
Mesh capable VSAT is the SatLink 1910 with Main board ID 1.1 and later equipped with the SL150
plug-in board. The CLI command “device show” in the example below shows the correct hardware
required for the mesh operation:
# device show

By default, mesh VSAT only supports 1 mesh connection, where a mesh connection is one QoS class link
to another mesh VSAT. Support for more simultaneous connections is achieved by purchasing a SW
license mesh-connection-n where n = 2, 4, 6, 8, 10, 14 or 16.
The example below shows the CLI command “sw show” printout at a VSAT supporting maximum of 8
simultaneous mesh connections. These 8 simultaneous connections can be realized as 4 QoS class links to
2 remote mesh VSATs, only 1 QoS class link to 8 remote mesh VSATs or any combination in between.
