Important Considerations
■
PACE technology is 3Com’s method to provide reliable timing, optimal
LAN bandwidth utilization, and data prioritization for time-sensitive
multimedia and real-time applications, and data-only applications.
■
PACE Interactive Access employs a “back-off” algorithm that enables
your system to control traffic flow on a point-to-point link with an end
station. When the network experiences congestion, the switch holds
packets. PACE Interactive Access prevents an end station from
“monopolizing” the link.
