Question

i want to implement multicast using python

can anyone tell me how can i get information on socket programming in python?

Answer 1

http://docs.python.org/library/socket.html
and
http://twistedmatrix.com/documents/current/core/howto/index.html

are both good resources. Twisted in highly recommended as an asynchronous programming api.

Answer 2

Answer 3

can you expalin the later one in a brief manner ?

i m a beginner in python

Answer 4

i have one code of client and server

where there can be multiple clients and one server

clients can send data to server and server can receive data from them

i want to implement multicast

where server can send data to clients (more than one ) can each clients receive data at the same time


i have certain change to that client server program but it gives me an error

Answer 5

i got this error

C:\Python27>python multiserver.py
Traceback (most recent call last):
File "multiserver.py", line 8, in <module>
UDPSock.bind(addr)
File "C:\Python27\lib\socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 10048] Only one usage of each socket address (protocol/netw
ork address/port) is normally permitted

i don't know what UDPSock.bind(addr) does

addr is a tuple

addr=(host,port)

Answer 6

in UDP terms, binding to an address allows you to either send datagrams from that address, or to receive datagrams others send to that address. For more info about these terms, read "Beej's guide to network programming" available in many translations
