the timing of packet delivery that can cause garbled sound, jerky images,
and delays).

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 module 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.
