Answer
Client requirements:
Notebook running Windows 98, Windows 95,
Windows NT (versions 4.0 or 3.51), 3Com
Megahertz LAN PC Card, and the TCP/IP
stack.
Network requirements:
Switched path between stations and single
broadcast domain.
Fast IP is designed to bypass the router,
particularly where the router is a bottleneck,
as well as to leverage the switched
infrastructure. For Fast IP to create short cuts
around routers, there must be a switched
path between source and destination.
Fast IP bypasses the router to provide
increased performance in switched networks
even if there are just a small number of
network nodes using Fast IP.
The performance gain obtained when
deploying Fast IP is directly related to traffic
load on the backbone router.
The more traffic is pumped to it, the bigger
the latency and response time and the
higher the performance gain.
Internal tests show performance increases in
the order of 600% when routers are loaded
at 70 to 75%.
