本文探讨了NS中的离散事件调度器及其在网络组件模拟中的应用。详细介绍了事件调度器如何帮助网络组件进行包处理延迟模拟及定时器设置。此外，文章还解释了网络对象如何使用事件调度器，并强调了数据路径与事件路径的区别。

==========================

This section talks about the discrete event schedulers of NS. As described in the Overview section, the main users of an event scheduler are network components that simulate packet-handling delay or that need timers. Figure 5 shows each network object using an event scheduler. Note that a network object that issues an event is the one who handles the event later at scheduled time. Also note that the data path between network objects is different from the event path. Actually, packets are handed from one network object to another using send(Packet* p) {target_->recv(p)}; method of the sender and recv(Packet*, Handler* h = 0) method of the receiver.
