How to set Send Buffer Size for sockets in python

Question

I have a client socket at my server end and what I want is to set Send buffer size for the socket just like I set Receive buffer size.Any idea on how I can set it? Because while sending huge data, the socket disconnects.

Solution 1

Use socket.setsockopt() and SO_SNDBUF:

socket.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, <value>)      

Where <value> is the buffer size you want to set as a Python int.

Example:

socket.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, 8192)  # Buffer size 8192

See: setsockopt

Solution 2

You can use socket.setsockopt():

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, size)
