What does "tons" mean? Tens? Hundreds?
my question is how should I handle receiving traffic from each
connection respectively?
You're really going to want to use "select". You can store the objects in
a dictionary where the key is the socket number. That way, you can use the
result of the select and get your network object directly.

I wrote code like this:
main proc:
import socket_thread
#start 1000 connection
while i<1000:
my_socket=socket_thread.socket_thread(i,host,port)
my_socket.send(some_data)
my_socket.recv()
This won't run as-is because you never assign to "i".
socket_thread.py
class socket_thread:
def __init__:
self.soc_handle=socket.socket(socket.IF_INET,socket.DGRAM)
def send(data):
self.soc_handle.send(data)
def recv():
while 1:
input_list,output_list,exec_list=select.select([self.soc_handle],[],[],
2)
data=input_list[0].recv(2048)
print data
But it does not work as I hope. main proc can only initiate one thread
and then trapped by it, cannot get out.
I'm sure I missed something but I don't know. Thanks for any help.
Your "socket_thread" class is just a normal class. You create an
instance, use it to send data, and then call its "recv" method, which
loops forever.
