Advantages of using Reference Model

1. A Software developers can focus on the functions of only one layer because they know in which another layer will handle the functions on that they are not presently working
2. If modifications are made to one layer, the contents of other layer do not get modified
3. The reference model also promotes compatibility. All the protocols written to conform to that model will work together if the software developer adheres to the specification which is outlined in the reference model. Compatibility makes the potential for a huge number of protocols to be written and used.
