Configuration
In this configuration, there are turboIP-45s in place in a simple Point-to-Point link, but there is more
than a single path available between the Hub and the Remote Sites. Path A is a fiber optic link, Path B is
a terrestrial T1 link, and Path C is a 1 Mbps satellite link. Routers are used at both sites to dynamically
select the best path available. The turboIP-45s are placed just before the router so that all traffic passes
through the turboIP-45s regardless of the path used. In this dynamic bandwidth environment, the
turboIP-45s need to set to Per-Connection Congestion Control to optimize the TCP acceleration for
whichever path is used.
The following table defines the configuration settings for each turboIP-45.
