1. A method for simulating delay in a receiving network node responding to a request, comprising the steps of:

  • responsive to a determination that a simulation is to be performed of the receiving network node receiving a request from a sending network node and sending, after a delay, a response to the sending network node, wherein the response services the request, intercepting one or more data packets of at least one of;

    the request from the sending network node to the receiving network node, wherein the data packets are not permitted to reach the receiving network node until after a specified delay time;

    ora response to the request, said response from the receiving network node to the sending network node, wherein the data packets are not permitted to reach the sending network node until after the specified delay time;

    in response to intercepting a data packet form the sending network node, sending an acknowledgment message to the sending network node, wherein the acknowledgment message simulates that the receiving network node has received the intercepted data packet;

    retaining the data packets;

    releasing the data packets after the specified delay time, wherein delaying the data packets simulates the receiving network node receiving the request from the sending network node and sending the response to the request after the specified delay time; and

    forwarding the data packets after the specified delay time to one of the receiving network node and the sending network node.
