“Middle mile” loosely refers to the network segment between local access and destination network.
From the perspective of a potential customer, it might refer to whatever happens between its connection with the service provider and its application in the cloud.
SD-WAN's core promise of optimizing network performance through load balancing—and cutting costs by integrating internet into the WAN—has proven attractive. And it's helped the service take root among many large enterprise network teams.
The landscape for SD-WAN vendors is vast. While the core features of SD-WAN are generally consistent, vendors vary on additional features, security, deployment models, and pricing structures.
Our SD-WAN Research Service details the different service features and pricing available across SD-WAN vendors.
While a fifteen-year friendship with Greg is not a prerequisite for guests on the pod, it sure makes for good conversation.
To kick off Season 3 of the WAN Manager Podcast, Greg calls on longtime colleague Rob Schult—who also happens to be a Research Director here at TeleGeography—to draw the connection between the wholesale market and the enterprise retail market.
What should IT infrastructure and sourcing teams pay attention to in the wholesale market most?
We've written before about how prices vary by geography.
Well, it almost goes without saying that they also change over time.
Product pricing is a key factor in deciding when and where to use MPLS, DIA, broadband, or other network connectivity services at each site.
But today we want to focus on the "where."
In the past few decades, the corporate WAN has undergone a few massive reformations.
Our analysis has taken us through a tour of the SD-WAN market, types of providers, service features, and pricing.
Today we apply SD-WAN prices to a hypothetical model of a global WAN to explore how different network configurations paired with SD-WAN can affect total WAN costs.
As workload migration to the cloud becomes the standard, enterprises are redesigning their WAN backbones to ameliorate internet performance.
However, improving your internet performance isn’t so easy-breezy when you're wrestling with unknowns—like the perfect combination of broadband and direct internet access or the right ISPs to modernize your network with.
TeleGeography Senior Manager Greg Bryan will join Singtel on December 1 at 10:30 a.m. SGT for a live discussion on this topic.
We were overdue to talk about what the future of hybrid work looks like—and what it means for WAN managers.
But our trusty WAN team is on top of it. On Tuesday they invited some experts to gather and talk through the major work-from-home considerations that linger as some employees start to head back into the office and others continue to operate remotely.
