In this configuration, there are turboIPs’ 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 turboIPs’ are placed just before the router so
that all traffic passes through the turboIP regardless of the path used. In this dynamic bandwidth
environment, the turboIPs’ need to set to Per-Connection Congestion Control to optimize the
TCP acceleration for whichever path is used.
