The software-defined networking revolution is underway, and while many enterprise IT departments are considering SD-WAN and SD-Access to help solve their networking bandwidth and provisioning issues, the same evolution is going at communications and Internet service providers too. This is great for both the service provider and their customers because a software-defined networking approach allows for better, faster, and more consistent delivery of communications services for everyone. It really is a win-win situation.
CSPs, ISPs, and cable operators run notoriously hardware-based businesses though, so software-defined may be undiscovered territory for many. That’s not surprising because they own and operate the physical “pipes” and services of communications—whether that be telecommunications, cable, or Internet. Many service provider networks are cable-based and cable networks are undergoing major transformations: migrating from analog to digital systems, adding capacity and scale, and deploying new and improved services to meet the increasing needs of their customers.
