System Features Congestion Control—The Congestion Control feature optimizes available buffer space in the Switch 2000 TR by using the buffering ability in all Token Ring end stations. This is especially useful when many ports are transmitting to a common port such as a server connection. Having conges- tion control eliminates the chances of dropped packets in high-traffic client-server environments. -
