    You don't give any context? This sounds like an exam question...
    The approach you take will differ widely depending on the purpose it is built for and what it has to handle.

    what about it?! the exam question is "do you feel a layered approach is suitable one when dealing with communications architecture? how many layers do you think are necessary? Justify your answer."

    Pick a few of the reasons from this list http://wiki.answers.com/Q/List_the_major_advantages_with_layered_approach_to_protocols

    The biggest advantage of layering is abstraction, each layer doesn't have to care about how the others are built or their protocol as long as their adhere to common standards.

    However there is also the arguement that layering can be too rigid and inflexible as described here http://tools.ietf.org/html/rfc3439#section-3
