There are basically two types of basic network administrator model in the network that is:
Protocol model:
This model is basically represent the 4 layer of the TCP/IP model as it describe the different functionality with the networking data which occur in the each layer of the protocol in the TCP/IP model.
Reference model:
The reference model basically provide the common reference and maintain the consistency in all the different types of the network protocol. The main purpose of this model is that it understand the different functionality of the OSI model and then used in different networking design.
