Tcp socket packet assembly

[m.prah...@live.de]

I have tcp socket and connected to the RecvCallback.

  Ptr<Socket> tcp_socket = Socket::CreateSocket(GetNode(), TcpSocketFactory::GetTypeId());

  tcp_socket->SetConnectCallback(MakeCallback(&ClientApplication::ConnectionSuccess, this), MakeCallback(&ClientApplication::ConnectionFailure, this));

  tcp_socket->SetRecvCallback(MakeCallback(&ClientApplication::ReceiveTcpPacket, this));

  tcp_socket->Connect(addr);

Now when I receive some data it is always fragmented. I know one solution is to increase the fragmentation limit, but thats now what I want.

How do I know if there will be another packet and when I'm done reading tcp packets?
