5 Advantages and Disadvantages of MPLS | Limitation & Benefits of MPLS

 

MPLS: What is it?

One method of WAN connectivity that regulates network functions is called Multiprotocol Label Switching (MPLS). With MPLS, many of the drawbacks of Internet Protocol (IP) routing are totally circumvented. It was introduced as a frame-relay network substitute. For their voice call and data needs, the telecommunications industry now favors this technology widely.

How does MPLS operate?

Router performance is the means by which an MPLS operates. The entrance router first receives a packet, which it then labels in order to identify itself. Next, the tagged packet is sent to other significant routers. With the label, packets may be readily identified by all other routers.

MPLS has numerous advantages for the communications infrastructure, however it isn't perfect. It is a good idea to weigh the advantages and disadvantages before selecting this network.

You will learn about the 5 Advantages and Disadvantages of MPLS | Limitation & Benefits of MPLS in this article. You will understand the pros and cons of MPLS usage by the end of this article.

Now let's get started,

Advantages of MPLS

1. Cost

With MPLS, sharing network resources is simple because it is a layer 3 technology. In addition, MPLS allows for the private routing of all client data.


2. Scalability

Scalability is a feature that MPLS makes readily available. When compared to other ways, it is far simpler. 

 

It is possible to scale up and down the MPLS based on need. Even in the event that thousands of sites are required.


3. Efficiency

With no jitter or packet loss, MPLS provides connections of far greater quality. 

 

Its use in conjunction with VoIP could result in higher productivity, indicating the possibility of achieving a constant performance.


4. Reliability

A multitude of elements contribute to MPLS's dependability. MPLS ensures that packets are delivered to their intended destination by using labels for packet forwarding. 

 

Additionally, network traffic can be assigned based on priority.


5. Bandwidth

Multiple traffic streams are supported by MPLS in the network. 

 

Furthermore, distinct portions of bandwidth can be allocated to different kinds of data, which indicates that bandwidth is being used to its fullest. 

 

There is a chance that the bandwidth will grow with all of these methods.

 

Disadvantages of MPLS

1. Security

The user has complete control over MPLS solution security. The MPLS provider does not offer any built-in security measures. 

 

Nonetheless, you might quickly lessen vulnerabilities and partially secure the network by cooperating with the supplier.


2. Maintenance

Even though MPLS is maintained by carriers, which reduces the network management workload, maintenance still demands a significant amount of work. 

In particular, it is not possible to perform all general maintenance tasks directly. An ISP is required to perform the maintenance. 

 

Now, because of the ISP's technical difficulties and some speed restrictions, this is not an easy task.


3. Control

In terms of having complete control over the network, MPLS is also lacking. The service provider handles all of the configuration. 

 

With MPLS, the user's only control is dynamic routing.


4. Deployment

When employing MPLS, deployment is a key concern. The process may become more complicated if the offices are spread out over multiple sites. 

 

Usually, it takes several weeks or even months to connect every office.


5. Accessibility

MPLS is not cloud application optimized. It is designed specifically for point-to-point communication. 

 

In other words, MPLS cannot be used to directly access a cloud application or SaaS. Certain cloud services are available, but they have a cost associated with them.
