MPLS Connections

Question 1

MPLS Connection (traditional networking technology)

Answer 1

routes traffic based on predetermined “labels”

(a tried and true networking technology that has powered enterprise networks for over two decades)

Question 2

Benefits of MPLS Connection

Answer 2

Businesses use MPLS to connect remote branch offices that require access to data or applications that reside in the organization’s data center or company headquarters.

Question 3

How MPLS Connection works

Answer 3

As data packets pass through the MPLS network, its labels are swapped by the routers. As the packet been through the boundary of the MPLS backbone it is examined, classified and assigned a label. after it, these packets forwarded to the next step in the pre-set Label Switched Path (LSP)

Question 4

MPLS Pros and Cons

Answer 4

The benefits of MPLS are scalability, performance, better bandwidth utilization, reduced network congestion and a better end-user experience.

MPLS itself does not provide encryption, but it is a virtual private network and, as such, is partitioned off from the public Internet. Therefore, MPLS is considered a secure transport mode. And it is not vulnerable to denial-of-service attacks, which might impact pure-IP-based networks.

Question 5

Why is MPLS not for Cloud/SaaS?

Answer 5

Once businesses transition to the cloud, the MPLS-based hub-and spoke model becomes inefficient because it routes traffic through corporate headquarters (hubs), which act as central choke points. It is more efficient to send traffic directly to the cloud. Also, the increased use of cloud services, video and mobile apps has driven up bandwidth requirements, and MPLS services are difficult to scale on demand.

Question 6

MPLS vs. SD-WAN

Answer 6

MPLS was a great innovation for its time, but there are newer technologies that better address today’s network architectures.

Software-defined WANs (SD-WAN) is architected with cloud connectivity in mind, which is why so many businesses have been replacing or augmenting their MPLS networks with SD-WAN.

Question 7

Is MPLS dead?

Answer 7

Small and mid-size businesses can likely sunset MPLS and shift solely to an all-broadband WAN because many of them have moved to an all-cloud IT model.

Larger enterprises, which may have sunk costs into MPLS networking, will likely take a hybrid approach, where they will keep MPLS for legacy apps that run on-net and then offload Internet traffic, like cloud, to the SD-WAN.

MPLS will continue to have a role connecting specific point-to-point locations, like large regional offices, retail facilities with point-of-sale systems, regional manufacturing facilities, and multiple data centers. MPLS is well suited for real-time applications like telepresence. And as Verizon (an MPLS provider, admittedly) points out, SD-WAN can actually help you get the most out of your MPLS connection.
