pub.py, sub.py : it shows how to subscribe messages from a zmq socket server 两个文件结合使用
no-bubfer.py: a demo for sub and pub. 一个文件中，同时有sub和pub
x-pub.py: it shows how to use xsub & xpub in a single file 一个文件，完整的xpub,xsub示例
an example for multi process, multi publisher, multi subscriber, 多个进程，多个publisher, 多个subscriber的例子
x-pub-monitor.py
x-pub-client.py
x-pub-client-new.py
Firstly, you start the x-pub-monitor.py,
then you can start x-pub-client.py, and x-pub-client2.py, and you will see that the two process will subscribed the same messages.
For easier comparison, I suggest to view the message recieving process in two vertical panel in tmux (http://tmux.sourceforge.net/):
In tmux, press Ctrl+B,% to split the screen vertically. Then Ctrl+B+Left, Ctrl+B+Right to swith the two panel.
You can start x-pub-client.py in the left panel of tmux, and x-pub-client-2.py in the right panel.
push.py pull.py
client和server是对等的，就是说可以在push侧bind，也可以在client侧bind，服务器端bind,客户端connect。 对于push/pull pattern，bind的socket会阻塞，直到客户端ready。
TCP使用示例: 对于TCP协议, server的一侧，服务器名要用星号*: python push.py "tcp://localhost:3100” python pull.py "tcp://*:3100"
IPC使用示例:
python push.py "ipc://name1:5678" python pull.py "ipc://name1:5678"
