使用Java制作多点发送程序(4)时间:2010-12-25 yesky 林建刚若要运用该应用程序，先编译MultiCastSender和MultiCastReceiver，然后将MultiCastReceiver传送到其它机器，以便能够演示多个参与者接收报文的情况，最后Java解释器运行该应用程序。例如：要向225.2.32.6组在端口1111上发送多点发送报文，应按如下方法进行： -/class ->java MultiCastSender225.2.32.6 1111 Here is just to test multicast message. Sending: Here is just to test multicast message. Do you received it? Sending: Do you received it? 要接收这些报文，应在一个或多个系统上运行MultiCastReceiver应用程序，这些系统应该加入同一个多点发送组225.2.32.6，并在相同的端口1111上侦听： -/class ->java MultiCastReceiver 225.2.32.6 1111 Received from 225.106.36.32 on port 32911: Here is just to test multicast message. Received from 225.106.36.32 on port 32911: Do you received it? |
