Brouting mode
Select this mode for all point-to-multipoint or unidirectional IP systems
where there is an indirect return path (i.e. not via satellite). Both the Tx and
Rx modems should have brouting enabled. In this mode, the Ethernet
bridge in the Tx modem does not expect to receive replies and simply
transmits all Ethernet frames over satellite other than those destined for
itself.
TCP acceleration mode
This mode provides bridging of non-TCP packets combined with
acceleration of TCP packets using a Performance Enhancing Proxy (PEP)
that overcomes performance problems associated with using standard TCP
over satellite.
TCP acceleration mode + Header Compression
Only applicable if an IP traffic Interface card is fitted. This mode provides
bridging of non-TCP packets, acceleration of TCP packets and header
compression.
Remote + TCP Acceleration
This mode supports point-to-multipoint TCP acceleration. The remote
modems should be set to this mode and VLAN filtering should also be
enabled.
Hub + TCP Acceleration
This mode supports point-to-multipoint TCP acceleration. The hub Tx
modem should be set to this mode and VLAN filtering should also be
enabled on this modem. Note that hub Rx-only modems in a point-to-
multipoint TCP acceleration system should be set to Hub mode (not Hub +
TCP Acceleration) and that the Rx-only modems should have VLAN filtering
disabled.
