An IP datagram is a data format that IP can identify. It is made up of two parts: the header and the data, both of which must be transferred. Except for the data, each field in the datagram has a distinct duty to play in data transfer. Except for the IP Options field, which can be 20–60 bytes long, every field in the IP datagram has a fixed size. Using the header, the transmitting computer sends a message to the protocol at the same layer on the destination computer. Data transfer becomes much easier if a datagram can fit inside a frame. If the datagram's size exceeds the maximum value that may be stored in the frame, the datagram must be broken into logical groupings known as fragments. In just a few circumstances, the size of a datagram will be much smaller than the maximum amount of data that can be sent across the physical media at any one moment. Padding is used in this example to fill up blank spaces. The Total Length field is used to determine the actual length of data provided across the frame.

The Types of Service (ToS) part is utilized to decide the sort of administration that should be given by the Internet layer contingent upon the kind of utilization for which the information move should be finished. The sorts of administrations that can be given by IP are augmenting unwavering quality and throughput and limiting expense and postponement. The size of the ToS part is 4 pieces. The Transport layer offers the benefit of this field to the Internet layer. Be that as it may, the qualities in these pieces are simply rules and not rules.

The devices that operate from the Internet layer use these values to transfer data. The values that can be assigned to this component and a description of each value is provided. For example, if the application is an Online Transaction Processing (OLTP) system, it will require the delay to be minimized and therefore the value would be 10002. However, in a situation where a bulk transfer of data is to be done, maximizing throughput will be appreciated and thus the value will be 01002. The Protocol field is utilized to determine the convention used to make the information present in the Data field. The size of this field is 8 pieces. The qualities that are relegated to the Protocol field are given in

IP gets information from all the higher layer conventions. Each layer in the TCP/IP reference model adds data to the information that will be deciphered by the companion conventions to execute specific errands. Hence, the information part of an IP datagram contains the first information that must be sent notwithstanding the headers added by the higher layer conventions. When the datagram is gotten at the objective, the information should be diverted to the fitting convention that is working in the higher layer. For instance, IP can collaborate with TCP or UDP in the higher layers. The convention assumes a significant part since messages can be deciphered exclusively by the convention that made them [1-5].
