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.
