SD-WAN as Intent-Based Networking: Opportunities Abound

M. Fratto

• Proscriptive network configurations work well, but they are static and unwieldy and don’t really reflect what IT wants or users expect.

• For many organizations, SD-WAN will be their first contact with intent-based networking, which can open many opportunities.

Admit it, you really want your computers to do what you want, not what you say, but computers are really only good at doing what you tell them—nothing more and nothing less. That paradigm has driven all of our human-computer interactions, including how IT systems are designed and operate. Continue reading “SD-WAN as Intent-Based Networking: Opportunities Abound”

The Case for SD-WAN

• Your organization may be in the minority that won’t benefit from SD-WAN products replacing your existing WAN infrastructure, but for everyone else, there’s significant upside to moving to SD-WAN sooner rather than later.

• Algorithms in SD-WAN products rationalize competing demands such as current conditions and your pre-defined requirements to optimize application performance. Let go and get on with your day.

There are too many times when I see a technology and think, “Yeah, I want to buy that.” I’m talking technology, not products, in this note. SD-WAN is one of those technologies that I think has so much upside that no matter what product you pick the result will be far and away better than what you have, in particular for interconnecting remote sites. I’m not entirely convinced of the efficacy of SD-WAN for inter-data center connectivity. The key feature is operational simplicity when compared to how inter-office connectivity is achieved today.

Three Key Networking Trends for 2016

Summary Bullets:

  • Enterprise SDN momentum is still slow to pick up indicating that enterprises are struggling to find relevant use cases or use cases with sufficient benefit.
  • Integration capabilities industry wide need to improve including technical implementations and go to market tactics that prioritize accessibility.

I dislike yearly predictions. If I could make accurate predictions I’d be rich and living on a beach somewhere pondering my next fruit and umbrella drink. But, I can see what enterprises are asking for from vendors and how various vendors are responding to those demands. The big picture end game that creates a great vision and makes for an exciting keynote on stage pixelates when it comes to practical questions on how products and services can positively impact an enterprise. I think there are three critical changes in the market occurring in 2016.

No Doubt About It: SD-WAN Products Are Popping Up Like Daisies

Summary Bullets:

  • Since 2012, the number of new products, product updates, and startups selling SD-WAN has been steadily increasing.
  • SD-WAN is attractive for both enterprises and service providers seeking to broaden their service portfolio, all of which will make for a very competitive field.

There’s nothing like a good visual to see if a technology is taking off. While putting together some data for a report on SD-WAN, I created a timeline of product launches and major product updates. To save space, I just listed the vendor, product, and version/feature. The items are ordered relative to each other, and I used dates from press releases or from conversations with the vendor. SD-WAN products create an over-the-top network between locations such as offices, data centers, and cloud services. SD-WAN relies on automation to create paths through the network based on policy requirements and definitions which may include path selection, application classification and management, and reporting. I’d even go so far as to say that any definition of SD-WAN requires encapsulation of traffic between sites as a fundamental component.

SD-WAN and IoT: A Long Road Ahead

•SD-WAN products are well suited to address the complexity and scale of IoTAs diversity in IoT grows.

• SD-WAN vendors will be challenged to address the specific needs of new and increasingly specialized IoT products.

Commercial IoT networking in the short term is more about connecting and protecting IoT devices and gateways that are already deployed, or will be soon, rather than having to support a raft of new, IP addressable devices. The IoT name has been equally applied to what otherwise are called sensor networks, command networks, industrial Ethernet, and other network-attached devices. SCADA devices certainly fall into this realm. The difference being that these devices are being connected—on purpose or inadvertently—to public networks and exposing them to the potential for additional attacks.
