Choosing a data exchange protocol

You need to choose a proper data exchange protocol to establish efficient communication between the prototype components. The choice is largely dependent on the communication function for which you intend to use the protocol. The functions are described by the Open Systems Interconnection (OSI) model. Note that some protocols can cover multiple functions.

The OSI model divides a communication system into a number of abstraction layers (originally seven, as shown in the following table). Each layer is responsible for its specific jobs (functions), servicing the instances from an above layer and requesting services from an underlying one.

The following table shows seven layers of the OSI model:
