Is MPLS obsolete?

Summary

In this article, I will discuss the current state of MPLS (Multi-Protocol Label Switching) technology and its role in modern networking solutions. I will also explore the alternatives to MPLS, such as SD-WAN (Software-Defined Wide Area Networking), and compare their benefits and drawbacks.

Is MPLS going away?

MPLS is not dead. Despite the emergence of newer technologies like SD-WAN, MPLS remains a relevant and important networking option for many businesses.

What has replaced MPLS?

SD-WAN has emerged as a popular alternative to MPLS. It is a virtual WAN architecture that abstracts the networking layer, allowing for the use of different connection types interchangeably, including MPLS, broadband, DIA, and LTE.

Why is MPLS declining?

MPLS is facing challenges in terms of capacity and overall costs. As the demand for capacity increases, MPLS requires additional infrastructure to support it, leading to higher costs for businesses.

Why replace MPLS?

SD-WAN offers several benefits over MPLS, including reduced bandwidth costs. MPLS bandwidth is expensive compared to public Internet bandwidth, making SD-WAN a more cost-effective option for many businesses.

What is better than MPLS?

SD-WAN offers several advantages over MPLS, such as lower costs, easier deployment, more flexible configuration, higher performance, and stronger security for distributed users and workloads.

Does Verizon use MPLS?

Verizon offers Private IP (PIP), its global MPLS-based IP VPN service, which provides customers with any-to-any IP connectivity and the privacy and quality of service associated with Layer 2 services.

Why is Ethernet better than MPLS?

Carrier Ethernet is often considered a better option than traditional leased-line or MPLS circuits due to its dynamic architecture, lower cost, ease of management, and adaptability for high-bandwidth applications.

What are the disadvantages of MPLS?

MPLS has some drawbacks, including its optimization for point-to-point connectivity only, long deployment times for offices in different countries or states, the need for WAN optimization to streamline delivery, and its higher cost compared to alternatives like Ethernet.

Where is MPLS used today?

MPLS is commonly used by businesses to connect remote branch offices to the central data center or company headquarters, providing access to data and applications.

Which is better, MPLS or VPN?

Both MPLS and VPN offer enhanced security, but VPNs provide encryption as a standard feature and work up to OSI Layer 7, making them preferable for scenarios where security is more important than speed.

Why replace MPLS with SD-WAN?

SD-WAN provides similar performance and reliability to a dedicated MPLS circuit but achieves it through aggregating various transport media and optimizing traffic routing, rather than relying on predefined, dedicated links.

What are the cons of MPLS?

MPLS has limitations, including its optimization for point-to-point connectivity only, lengthy deployment times for offices in different countries or states, the need for WAN optimization, and higher costs compared to alternatives like Ethernet.

Which is better, MPLS or SD-WAN?

MPLS services often include quality-of-service guarantees, while SD-WAN leverages best effort Internet services that may experience occasional packet loss. However, most SD-WAN services compensate for this through various mechanisms.

Questions and Answers

1. Is MPLS going away?

No, MPLS is most definitely not dead. In fact, while newer technologies like SD-WAN are understandably gaining momentum, MPLS remains a relevant and important networking option that will play a crucial role for many businesses in the years ahead.

2. What has replaced MPLS?

The best alternative to MPLS is an SD-WAN network. SD-WAN is a virtual WAN architecture that uses software to abstract the networking layer, allowing you to use varying connection types interchangeably. Connectivity options include MPLS, broadband, dedicated internet access (DIA), and LTE.

3. Why is MPLS declining?

MPLS is falling down on the job in capacity, especially as that capacity requires still more infrastructure to support. The combination of high overall costs and capacity issues poses an entirely new problem when it comes to MPLS: bandwidth costs.

4. Why replace MPLS?

What are the benefits of SD-WAN Reduced Bandwidth Costs: MPLS bandwidth is expensive. On a “dollar per bit” basis, MPLS is significantly higher than public Internet bandwidth. Exactly how much more expensive will depend on a number of variables, not the least of which is location.

5. What is better than MPLS?

Why Is SD-WAN Better than MPLS SD-WAN can use any combination of connections, whereas MPLS requires static, dedicated network connections. This allows SD-WAN to offer lower costs, easier deployment, more flexible configuration, higher performance, and stronger security for distributed users and workloads.

6. Does Verizon use MPLS?

Private IP (PIP) is Verizon’s global MPLS-based IP VPN service that offers customers any-to-any IP connectivity with the privacy and quality of service (QoS) associated with Layer 2 services.

7. Why is Ethernet better than MPLS?

Compared to the traditional leased-line or MPLS circuits and because of its dynamic architecture, Carrier Ethernet can meet many of the enterprise WAN requirements at a much lower cost. It’s also easier to manage and is adaptable for today’s high-bandwidth applications.
