Setting the traffic class in ServerSocket

Question

Hi all,
in a ServerSocket I want to mark the dscp fields of the packets which are flowing through the client. I set the traffic class field as follows:
Socket inSock = serverSocket.accept();
inSock.setTrafficClass(64);
but this has a problem that the first packet sent by the inSock cannot be marked. This occurs because the first packet is sent in the accept() method, but I set the traffic class after this packet is sent. Then do you know any solution to set the tos as the default (set before the first packet) option for all sockets accepted by a ServerSocket.
I have some very workaround solutions such as implementing the SocketImpl and etc.But I want a KISS (Keep it simple stupid).
Thanks.

Answer 1

Yes thanks for your offer it would be good approach. but this arouses a new problem that my ServerSocket are created by a factory and I need to find a transparent solution in which for all ServerSocketFactory objects my solution works well. Let's see the example.
MyChannel(ServerSocketFactory f) {
ServerSocket serverSock = f.createServerSocket(param1, param2, ....);
Socket inSock = serverSock.accep();
In this case how can I morph the serverSock instance to my MySpecialServerSocket object for example.
Indeed I need only overriding accept method, and I need this to do for an instance not an object.
Do you know any way to do it?
For example we can do a thing as follows:
MyObject ob = new MyObject() {
public overridenMethod() {
};
