1) It's the size in Bytes of the TCP payload, excluding TCP header and IP header. eg. If you set packetSize_ of the TCP Agent to be 1000, then the actual size of the IP datagram is 1040. You can validate this from the trace file. 2) I don't think it matters anything. Queue limit is measured in packets. The size of the packet doesn't affect anything. 3) I'm not sure about it.
