This paper is concerned with the optimum routing and flow assignment problem in packet-switch networks. The optimum objective function is the network-wide average time delay.
研究分组交换网的路由选择及流量分配问题，以网络的平均时延为优化目标函数。

As Figure 1 shows, this functionality is represented by a switch, which enables efficient packet communication among the participating endpoints.
正如图1所示，这个在功能上表示为一个交换机，它支持参与其中的端点间的高效数据包通信。

Depending on the nature of the problem, it is sometimes good practice to run a tcpdump for a period of time while capturing packet information to a file using the -w switch.
