Hi Jyoti, At this point in time I don't think this is available. Are you suggesting that, if an operator can indicate the 'space' available/congestion on it's end that the SMPP connection will increase/decrease it's rate of submitting messages from the internal queue dynamically? I think this would be possible if the operator supports this feature of course.

This recognises that a SMSC or ESME may be under varying levels of stress and that predetermined performance is not always guaranteed.

Is this the solution for achiving flow control ?. i.e re-queue of message after geting a error code.

Well, in that case, your 'receiver' should send you the appropriate error code in the command status of the response PDU. For instance ESME_RMSGQFUL and ESME_RTHROTTLED will cause the message to be re-queued in Kannel.

Hi, What you are telling is not flow control or windowing. Real flow control is the concept of a receiver informing the sender that it can't accept any more data. Not that configuring statically before the process begins.
