DataInputStream with slow client side connection

Question

I need to stream some data to client. server pushes all messages once connection is established over internet.
but when internet connection is slow (like wireless). i see lot more messages in receive Queue on client side. then for a brief period of time, server stops sending messages (may be due to socket channel is full or something)
so it looks like application is stealth mode. then all of sudden application starts consuming messages (may be when that channel gets empty)
any idea how to fix this slow connection issue? i don't care if client drops certain messages. how can i flush or empty out that socket channel ?
below is the code snippet that i am using...
try {
       InputStream is = new URL(streamerUrl).openStream();
       ds = new DataInputStream(new BufferedInputStream(is));
       parseBody(ds);
    } catch (IOException ex) {
                    logger.error(ex.getMessage());
    }

My decision was to send acknowledge and if server side can't get to acknowledge it will skip all new messages.If the server can't get an acknowledgment it can only mean that the connection has failed, which will manifest itself to the server as an IOException: 'connection reset' on a write. The acknowledgement adds nothing except latency and more bandwidth usage.
So why not skip message while network lacking.I agree, but why not use what the network is already telling you, rather than adding more messages and more failure modes? Now it's the client that has to look out for connection resets. You've just moved the problem.
