Citing Our WAN Sources
In our latest episode of the podcast, we dig into sourcing. Our listeners know that we often discuss the migration of large enterprises away from one or two global suppliers for a mostly MPLS network to a novel mix of transport types and suppliers. This is especially true due to changing trends in cloud migration, SD-WAN, and security.

Nailing Down Network-as-a-Service
Our data shows that most enterprises have more than one IaaS provider. For SaaS, that number can be dozens, hundreds, or even more. Most have moved the majority of their data centers off corporate premises to some kind of shared facility.
This means most companies are dealing with multi-cloud connectivity in some form; WAN managers, of course, have to handle that from a performance and cost perspective.
Last month Luxembourg-based Millicom International Cellular sealed a pair of deals that will see it exit the African telecom sector once and for all.
Its stake in Ghanaian joint venture AirtelTigo was sold to the country’s government. Tigo Tanzania and Zanzibar Telecommunication (Zantel) were offloaded to a consortium led by Axian—the company that previously acquired Millicom’s Senegal-based business in 2018.

We're going back to the middle. The middle mile, that is.
Like many telecom terms, this is one that you might have to follow up with, “what exactly do you mean by that?”

What Role Will MPLS Play in the Future of the WAN?
The average enterprise network had MPLS running at 82% of sites in 2018. That fell to just 58% in 2020. About one-third of those networks have active backups for their MPLS service—a quarter of them have passive backups.
Looking at these numbers, we have to ask: what role will MPLS play in the WAN moving forward?
In September 2020, U.S. telecom giant Verizon announced the surprise takeover of prepaid MVNO TracFone Wireless. The deal is worth a whopping $6.25 billion.
Verizon hopes that the transaction will help it compete in the prepaid space, where T-Mobile U.S. and AT&T rule the roost with their Metro by T-Mobile and Cricket Wireless brands.
Despite the expanding role satellite providers have in delivering connectivity, the vast majority of intercontinental capacity is carried by submarine cables.
This will likely always be the case, but new constellation projects are poised to reshape how broadband is delivered to end users.
