5 Advantages and Disadvantages of OSI Model | Drawbacks & Benefits of OSI Model

 

OSI Model: What is it?

One kind of reference model that links many systems is called Open System Interconnection, or OSI. Regardless of their architecture, computers worldwide will be able to communicate with one another because to OSI. The OSI model consists of seven layers, each of which is assigned a distinct responsibility. 

Why was OSI Model introduced?

The networking model TCP/IP was challenged by OSI. In order to facilitate successful communication between computers made by different manufacturers, the OSI and TCP/IP models offer a neutral networking environment. Nonetheless, a few significant distinctions set them apart. Even though OSI makes communication easier, there are still certain issues. Like other networking architectures, OSI has its share of benefits and drawbacks.


I will discuss the 5 Advantages and Disadvantages of OSI Model | Drawbacks & Benefits of OSI Model. You will learn the pros and cons of adopting the OSI model from this essay.

Now let's get started,

 

Advantages of OSI Model

1. Network Support

By default, the OSI model is general. This indicates that a large number of device manufacturers support it. The OSI standard model is used by the majority of computer networks.


2. Layer Changes

In the OSI model, each layer is isolated from the others. As a result, modifications to one layer won't have an impact on the other. If the layer interface changes, though, this cannot be assured.


3. Layer Identification

In the OSI model, the tasks of services, protocols, and interfaces are delegated to each layer. However, the OSI model can distinguish between the tasks in each layer with clarity. As a result, every device that adheres to the OSI model will be able to assist one another.


4. Flexibility

Because the OSI paradigm may be used with both connection-oriented and connectionless services, it is extremely adaptable. You can employ connection-oriented services in situations where maintaining reliability is necessary. 

 

On the other hand, connectionless services are the greatest choice when it comes to data transmission speed.


5. Troubleshooting

Troubleshooting is made easier by the OSI model's separation of layers from one another. Examining each layer would help a network administrator locate the problem more quickly in the event of a failure. This analysis of the entire network saves time. 

 

Disadvantages of OSI Model

1. Implementation

The OSI model is wholly theoretical. It implies that it is nearly impossible to accomplish in practice. even without the necessary technological support. Additionally, the implementation costs are typically higher in this case.


2. Adaptation

Because of the TCP/IP paradigm's widespread use, many businesses were first hesitant to adopt the OSI model. Long before the ISO paradigm was in use, there was the TCP/IP model. As a result, businesses were not prepared to embrace this change.


3. Effectiveness

In contrast to TCP/IP, an OSI model fell short of the realistic expectations. It is therefore ineffective when used as a TCP/IP paradigm. As a result, the majority of people started to view the OSI model as inadequate.


4. Complexity

The structure of an OSI model is more intricate than that of a TCP/IP model. This is a result of several layers present that are not optimized. 

 

For instance, different layers perform different duties when it comes to data links and networks. Additionally, there are redundant services. that is, the identical task is processed by two or more layers.


5. Collaboration

The OSI model has several operational problems as well. In the OSI paradigm, no layer can function in parallel. The OSI model's layers cannot function unless the data from the preceding layer is sent through.
