In modern protocol design, protocols are layered to type a protocol stack. Layering is a design precept that divides the protocol design task into smaller steps, each of which accomplishes a particular part, interacting with the other components of the protocol solely in a small variety of well-defined ways. Layering allows the components of a protocol to be designed and examined and not using a combinatorial explosion of instances, keeping every design comparatively simple. Systems usually do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol suite.
