Client/server application in Python

[pdbarnes]

Hello Folks,

We'd like to write an client/server application pair entirely in Python.  Cribbing from the C++ implementations of OnOffApplication and PacketSink, we imagine something like

class MyApp(ns3.Application):

 def Start(self):
   # _socket is meant to be a private member of MyApp
   _socket = ns3.Socket…
   _socket.SetRecvCallback(self.Receive)

 def Send(self):
   # Protocol header
   header = ...
   # Size of data packet we need
   size = header.GetSerializedSize()
   packet = ns3.network.Packet(size)
   packet.AddHeader(header)
   _socket.Send(packet)

 def Receive(self, packet):
   packet = _socket.Recv()
   ...

Does this seem feasible? Could anyone point us to a working example along these lines?  Or another approach?

Thanks,

Peter

Hello Peter (and all), 

I was thinking on doing something similar. Have you managed to build a python custom application? Is there any answer to this?

Best regards,

Sergio

Hello Sergio,

Sorry I've taken so long to reply.  No we haven't tried this.  It came up for us as a possible way approach in another domain, so we wondered if this was even possible.

Let me know if you get something working; I'd be interested.

Thanks,

Peter
