Description Gustavo J. A. M. Carneiro 2010-03-04 11:07:57 EST

It appears there's a receive queue in PacketSocket.  This queue is unlimited by default.

1. Unlimited by default is highly unrealistic;

2. Why is there a receive queue at all?  UDP sockets do not have RX queue...

This cost me days of debugging *sigh*  I had already filed a bug for TCP tx buffer being unlimited, but did not realize at the time that the packet socket had an equally evil infinite queue :-|

And because of missing NS_OBJECT_ENSURE_REGISTERED and packet-socket.h not being a public header, I can't even change the default value of ns3::PacketSocket::RcvBufSize from Python.  Great.

I was wrong about UDP, it also has a receive buffer, also unlimited by default.
