SD-WAN: Threat or Opportunity?

SD-WAN is a rapidly growing use case for SDN in the WAN that promises a more cost-effective and simpler way to operate secure, virtualized WAN connectivity between enterprise branches and corporate data centers. While the benefits for enterprises are fairly straightforward – lower connectivity costs and OpEx compared to traditional MPLS, as well as improved WAN visibility and control – SD-WAN’s benefits for service providers aren’t nearly as clear.

In fact, SD-WAN in its purest form can be considered a threat to service providers. How so? To explain, it's important to first clarify that SD-WAN is an overlay technology, meaning that the virtual connections that make up an SD-WAN run "over-the-top" of the public Internet, and leverage lower-price broadband access links (DSL, PON, LTE etc.).

This threatens service providers because as enterprises transition to private over-the-top WAN connectivity, common sense tells us that a reduction in higher-price MPLS services is sure to follow. Perhaps even more importantly, the service provider also risks losing customer control and mindshare to a new generation of over-the-top solution providers, much like they’ve been impacted by Amazon, Microsoft and other cloud service providers over the past several years.

While the benefits for enterprises are fairly straightforward – lower connectivity costs and OpEx compared to traditional MPLS, as well as improved WAN visibility and control – SD-WAN’s benefits for service providers aren’t nearly as clear.

But as we learn in any SWOT analysis, a threat can also be an opportunity if you take the initiative. A growing number of service providers are doing just that and capitalizing on the rapidly growing demand by offering SD-WAN as a managed service to enterprise customers. In addition to a compelling new service offering, and a new revenue stream, managed SD-WAN services can complement service providers' existing SDN and NFV initiatives, and accelerate their ongoing shift to virtualized services.

Key Challenges of SD-WAN Service Deployments

There are a number of key challenges related to SD-WAN service deployments that providers must navigate through when looking to take advantage of the SD-WAN service opportunity. These include:

Avoiding the creation of a new operational silo, and lock-in to any single SD-WAN vendor/solution
Integrating SD-WAN with the existing OSS/BSS for lifecycle management
Differentiating a managed WAN service offering

Ciena has multiple service provider customers who are pursuing this path today, and Blue Planet is helping them tackle these challenges.

A growing number of service providers are capitalizing on rapidly growing demand by offering SD-WAN as a managed service to enterprise customers.
