+This demo illustrates how to use UDP multicast to send messages.
+
+To run the demo, first start multiple instances of the server:
+
+$ server
+
+In a separate window, start a client:
+
+$ client
+
+When you send a message you will notice that it is received by all
+running servers.

+To run the demo, first start multiple instances of the server:

+
+In a separate window, start a client:
+

+
+When you send a message you will notice that it is received by all

+This demo illustrates how to use UDP multicast to send messages.
+
+To run the demo, first start multiple instances of the server:
+
+$ java Server
+
+In a separate window, start a client:
+
+$ java Client
+
+When you send a message you will notice that it is received by all
+running servers.
