When designing a communications network or a control network we focus on existing hardware technology, new hardware technology, interfacing, network volume and speeds.  Often times new hardware technology needs to interface with existing hardware and the existing communication or network  protocols.  The two do not always easily  interface or may not interface at all. We will evaluate the  most cost efficient options for  migrating two different protocols so they will work together. In doing so we will review the amount of traffic and data that  needs to be transmitted.  Also the speeds and frequency at which the data needs to sent and received.
