Multiprotocol Label Switching, or MPLS, is used for rerouting or setting traffic routes using labels over private wide-area networks(WAN). Developed in the 1990s, it was used to speed up networks on an enterprise level. MPLS transmits data packets on predefined network paths and can only function in a limited area. Therefore, the technology demanded evolution and the advent of SD-WAN came to light.
SD-WAN technology transformed the networking methods on an enterprise level. SD-WAN stands for software-defined Wide Area Network. It is primarily dependent on software, thus, easy to deploy, operate, and maintain. It has become a popular alternative to MPLS. In this article, we are going to learn why SD-WAN took over MPLS and what are its benefits.
Let’s know a little about MPLS
Before we move further, we should learn a little about MPLS.
MPLS uses labels to transfer data packets in place of using network addresses. MPLS architecture is faster and more reliable than IP routing. It can be integrated with an existing infrastructure.
It was fine until it cost more expensive than regular internet services and consumed a lot of time for deployment. In addition, it lacked security features to combat the emerging cyber threats that advance with each passing day. Also, at one point in time, cloud computing became crucial for enterprises to operate from distributed working locations. And, MPLS, in some way, failed here.
So, SD-WAN technology has taken the limelight now for its faster deployment, quick functions, advanced security, and encrypted features.
Introduction to SD-WAN
SD-WAN solutions are a great way to support working in a cloud environment. Now, almost every enterprise supports distributed workstations. So, adopting SD-WAN tools is the best for them. In addition, you don’t need dedicated hardware for SD-WAN orchestration. It can be deployed in a very few time if compared to MPLS technology.
Let’s differentiate between MPLS & SD-WAN architecture
Enterprises must deploy the best technology of their time to stay ahead of their competitors. Because, in this era, technology is the only virtue that can transform the identity of an enterprise. Currently, SD-WAN infrastructure is evolving and taking enterprises to new dimensions of success.
Let’s discuss the key features of MPLS and SD-WAN to know why the latter is ruling over the world:
Deployment
In terms of deployment, MPLS requires a robust and secure dedicated physical connectivity circuit for deployment. Whereas, deploying SD-WAN architecture to an enterprise requires the creation of an overlay. An overlay is a virtual network that is constructed over physical connections of the internet or MPLS lines. Meanwhile, you will need to configure specialized routers to transfer data packets correctly.
Setup costs
MPLS turns out to be an expensive option for connectivity. It requires dedicated physical infrastructure and specialized equipment. And, maybe you will need to hire a specialized IT team to deploy a robust MPLS networking architecture.
The setup costs for deploying an SD-WAN architecture are way less than that for MPLS. It is because you can utilize an existing networking architecture to build an overlay on its top. Further, it gives you the flexibility to choose cost-efficient networks for establishing a networking infrastructure in your enterprise.
Performance and reliability
If we talk about the performance of MPLS, it can function in a predictable manner. The thing is you need to reconfigure it if you want to enhance its capacity beyond its pre-set limit. It can only perform well for the applications for which it has been designed.
SD-WAN offers flexibility in enhancing its capacity as per the application type & requirement. It can function very well and does not break down. in addition, you can choose a bandwidth from 5G, LTE, broadband, etc to meet your application’s requirements.
Scalability
Scalability with an MPLS technology demands reconfiguration and installation of new hardware. It can be expensive for a company to expand using MPLS.
Talking about SD-WAN can relax you. As you already know, SD-WAN offers flexibility in choosing bandwidths and can perform efficiently for any application. In the same way, if you are thinking to expand your company, you do not need to worry anymore. A little configuration in the software & programs will be sufficient to enhance the capacity of your enterprise operations.
Security
The use of an MPLS line is limited to a single enterprise only. And, it can be considered as private for that reason, but not secure. In addition, it does not follow any encryption or firewalls for protection of data.
While, SD-WAN architecture is secured by encryption layers, next generation firewalls, and IPv4 protocols. It supports distributed workspaces, still no one can read your enterprise data in between the transmission lines because of high security.
Management, maintenance, and monitoring
SD-WAN infrastructure is embedded with AI and ML tools now. So, its management and maintenance is super-easy. You do not require any specialized network administrator to monitor the activities on the networking route.
While MPLS requires expert IT personnel for configuration, upgrades, and other routine tasks in an enterprise.
Summary
If you have gone through this article, then you must agree on the fact that SD-WAN is the most preferable and favorable technology for enterprises. Today, cyber crimes have become common and emerging in new avatars. MPLS neither has to capacity to handle dynamic transformations in today’s application requirements nor it is secure enough to tackle constantly evolving cyber threats. So, you must choose SD-WAN solutions for a secure and robust digital infrastructure.
FAQs
- How is SD-WAN technology better than MPLS?
The biggest perk of SD-WAN technology over MPLS is that you can choose any bandwidth to meet your application’s requirements. In addition, you will not require specialized hardware to deploy SD-WAN tools. Rather than this, you can deploy it by creating an overlay on existing hardware.
- Is MPLS secure?
You can call MPLS a private connection but not secure. It is because an MPLS line functions within an enterprise limits only.
- How is MPLS inefficient?
The performance and functions of MPLS are limited. You cannot upscale this technology or enhance its capacity to meet the requirements of some newly introduced application in the enterprise.
