Its unclear to me what the "standard read" is that you are referring to.
There are well established solutions to most networking communication and
reading scenarios. However, it is not clear to me from your post exactly
what your specific scenario is. For example what is the protocol? What kind
of data are you retrieving? How are you defining a "standard read"?
With more information, you will have better luck getting a solution that
works for your use case.
