The typical model of output queueing in ATM switching has ideal performance, but is difficult to realize because of the need of high speed transfer that is N times the portspeed.
典型的ATM输出缓冲交换结构有着理想的性能，但需要N倍端口速率的高速传送而难以实现。

The first thing you should do is make sure all servers are locked down to the highest speed possible using full duplex and the switch port is set to match.
应该做的第一件事是，确保所有服务器使用全双工和最高的网络速度，并相应地匹配交换机端口。
