Chapter 7. Sample Configurations
7.1 Sample Configurations Introduction
This chapter will describe typical topologies that the turboIP™ can be used in. Each sample
configuration will show how the turboIP™ would be configured for optimal performance. The
following list will apply to the turboIP™ in all cases –
• The turboIP™ must be placed in the network so that all TCP traffic that is to be
accelerated will be directed through the turboIP™. The local network would be
connected to turboIP™ LAN port and the WAN port would be connected to the satellite
modem (or to a router which connects directly to the satellite modem).
• With easyConnect™ mode, the turboIP™ is never a “Next Hop” or a Default Gateway
for any locally attached devices. Instead, the turboIP ™ will work as a transparent bridge,
so a turboIP™ can be placed in any network without having to reconfigure any network
devices.
• The turboIP™ Fail-to-Wire feature insures that all traffic continues to flow, even if there
is a turboIP™ failure, such as a power supply failure.
• The turboIP™ is fully compatible with network devices that use TCP, supporting
existing Internet standards, including network congestion and retransmission schemes.
This allows turboIP™ at one end of the link to operate with TCP devices at the other end
of the link without the need for a peer turboIP™ device, providing partial performance
enhancement. However, it is recommended that TCP traffic pass through a pair of
turboIP Performance Enhancement Proxies, in order to take full advantage of the SCPS-
TP protocol.
The following sections show and describe the addition of turboIP™ to an existing network.
