Traditionally, enterprises built their WANs using multiprotocol label switching (MPLS) services, and backhauled Internet traffic from their branch offices through their corporate data centers. While backhauling enables organizations to centralize Internet security, it creates performance problems with cloud-based services.

The rise of the cloud has contributed to the rapid growth of the software-defined WAN (SD-WAN) market, which IDC expects to reach $8 billion by 2021. IDC recently published the results of an extensive global survey of current and future enterprise plans for SD-WAN adoption. The study examines the relationship between SD-WAN and cloud services, WAN management and operational requirements, and the potential impact SD-WAN will have on overall enterprise IT efficiency.

IDC surveyed more than 1,200 midmarket and enterprise organizations worldwide to determine their needs and priorities for SD-WAN. The study found that SD-WAN enables these organizations to optimize their cloud applications and create a dynamic and secure WAN across branch locations. Enterprises said they are using SD-WAN to simplify WAN infrastructure, use multiple WAN providers and to offload non-critical business apps to broadband Internet services.

The top driver for SD-WAN adoption is “bandwidth optimization,” cited by 36 percent of survey respondents. Organizations are also looking to SD-WAN for “consistent application security” (31 percent) and “improved automation and self-provisioning” (28 percent). Faster deployment, operational efficiency and reduced IT complexity also ranked high as motivational factors for enterprises considering SD-WAN.

Small Business and SD-WAN

But what about small businesses? They have many of these same needs, and generally lack the IT resources to implement and support complicated networking equipment. Their ideal SD-WAN solution would be a plug-and-play appliance that integrates seamlessly with their existing infrastructure. Trouble is, most SD-WAN solutions are designed for large enterprises, with complicated configurations, policy definitions and management.

InSpeed is different. Plug it in, turn it on and it automatically begins streamlining the Internet, creating a self-driving WAN that eliminates management headaches. InSpeed enables organizations of all sizes—and even home office workers—to optimize interactive and cloud-based applications without breaking their budgets.

The IDC report also notes that SD-WAN allows organizations to take advantage of multiple connectivity options. The centralized controller that’s core to SD-WAN technology makes it possible to leverage a hybrid WAN that incorporates broadband, 4G/LTE and satellite services. A software overlay abstracts the complexity of the underlying networks, and application and network visibility enable intelligent path selection across WAN links.

This flexibility is a godsend for locations that lack access to reliable Internet services, as well as for temporary sites and Internet of Things (IoT) applications. Multiple connections also provide a hedge against service provider outages, improving business continuity.

Of course, making all this work properly is immensely difficult. Enterprise SD-WAN solutions typically provide administrative interfaces so that network engineers can implement failover policies and control each connection. Some vendors have introduced so-called “edge” solutions that are less complex but also have fewer capabilities.
InSpeed works with any WAN connection, and makes routing decisions inside the InSpeed cloud. It adjusts to the bandwidth that’s available, ensuring top performance for voice, videoconferencing and cloud-based services.

The IT requirements of branch locations have gotten pretty complicated. Organizations in retail, hospitality, education, healthcare and many other sectors are implementing advanced applications, high-end audio/visual technology and sophisticated collaboration tools across their remote offices.

In many cases, there’s no onsite IT support for these locations. The headquarters IT team has to maintain the technology in remote offices on top of managing mission-critical systems and applications, responding to end-user support requests, and trying to stay a step ahead of security threats.

The right SD-WAN solution can help reduce that burden. SD-WAN applies software-defined principles to WAN connectivity, eliminating the need for complex, manual configurations at the device level. Routing decisions are made based upon policies, and the entire WAN can be managed from one centralized controller.

InSpeed Networks takes this a step further, eliminating the need for IT to define policies. Plug in an InSpeed appliance and it automatically begins managing WAN traffic. All of your remote locations enjoy high-quality voice and video and improved application performance, with zero management headaches.

Which Way To SD-WAN?

Choosing The Right SD-WAN Solution For Your Organization

The Software-Defined WAN (SD-WAN) market is exciting. Unfortunately, it’s confusing, too. This confusion is due in part to the sweeping promises of some SD-WAN vendors to solve all possible network ills with a Swiss Army Knife approach, leading to complex products and a bewildering array of options. The confusion is also due to terminology. Just as the phrase “Unified Communications” took on a lot of different (and sometimes conflicting) meanings early in that market’s evolution, so “SD-WAN” has come to mean different things to different people today.

Unrealistic promises and vague terminology make product comparisons difficult. As a result, many IT managers are having a hard time deciding which SD-WAN solution is the right one for their organization.

What does SD-WAN really mean? And how, given all these different definitions and products, should an organization go about selecting the SD-WAN solution that meets its particular needs?

CTA - Which Way to SD-WAN?


SD-WAN Defined

Let’s start with the basics. Here’s a pared-down, no-frills definition of SD-WAN:

SD-WAN is formally defined as the application of Software-Defined Networking (SDN) ideas to WAN connections, which are used to connect enterprise networks – including branch offices and data centers – over large geographic distances.

InSpeed Networks is the only provider of SD-WAN solutions that were designed from the ground-up to address the needs of interactive applications. InSpeed’s solutions use unique proprietary technology that combine voice prioritization, with dynamic congestion management, to guarantee optimum performance for voice traffic, and improve overall throughput for data traffic, even over a single link.

Although the SD-WAN market is crowded with many players, including big name network equipment providers and new innovative start-ups, all SD-WAN solutions today include the following features:

  • A central controller that establishes network-wide policies and determines roles for each network device under management.
  • Commodity vanilla hardware runs the networking function.

Industry analyst firm Gartner suggests that, in addition to providing these basic features, SD-WAN solutions should also provide the following:

  • Support for multiple types of network connections (MPLS, cable, DSL, LTE)
  • Support for VPNs
  • Dynamic load-sharing of traffic over multiple connections
  • A simple management interface and support for zero-touch provisioning

Why provide networking features in software in the first place? In part, to benefit from the flexibility and scalability of cloud computing. When network controls are implemented in software, they can be deployed wherever makes the most sense—in virtual machines on premises, in a dedicated data center, or even in a public cloud—and they can scale dynamically to meet performance and usage requirements that fluctuate in real time. Simply put: Software-defined networking solutions can match or exceed the performance of earlier solutions while delivering the cost savings for which cloud computing is famous.


Bold Promises, Mixed Results

SD-WAN sounds great in theory, but in practice many SD-WAN solutions on the market today have not delivered on their promises. Complex provisioning and maintenance, incompatibility with existing network elements, and the inability to adjust automatically to changing network conditions, have led to iffy cost savings and questionable improvements in service quality.

What many SMBs and enterprises need is a solution that moves beyond SD-WAN to provide:

  • A comprehensive service, not a toolkit that requires sophisticated IT staff to implement
  • A solution targeted at essential enterprise needs such as Unified Communications, high quality voice or smooth videoconferencing—applications that employees and customers depend on, but which are poorly served by most SD-WAN solutions. Beyond replicating basic network routing features in software, the optimal SD-WAN solution will shape WAN traffic in real time to minimize network latency problems that lead to “robot voice” on VoIP calls and frozen frames/distorted audio in videoconferencing sessions.
  • A self-driving service that requires no on-going administration—an essential capability for supporting branch offices that have little or no IT staff.
  • Traffic optimization over a single WAN link, eliminating the expense and overhead of provisioning, managing, and paying for redundant links.


Selecting an SD-WAN Solution

When evaluating SD-WAN solutions, it’s important to consider the following issues:

Controlling your network

  • Is there a single point of administration and centralized control?
  • Do you have the manpower to administer yet another networking technology, or would you prefer one that is autonomous?

Traditional MPLS WAN vs Commodity Internet Plus SD-WAN

  • What is your current monthly cost for your network connectivity?
  • Would scaling up your current WAN technology be affordable? Are you sure that scaling would fix your QoS issues with interactive applications?
  • Are you looking to save money, increase throughput and ensure high quality voice calls?

Public Internet WAN

  • Does your current Internet connectivity provider offer optimized redundancy for your needs (active-active or active-passive)?
  • Would an overlay SD-WAN solution with your existing WAN provider solve critical QoS problems for interactive communications and meet your organization’s SD-WAN needs?

Requirements for Business Continuity

  • Has you measured the business costs of interruptions to IP telephony and videoconferencing services?
  • To achieve business goals, customer satisfaction goals, and SLAs, does your organization require virtually no Internet connectivity downtime?
  • How much investment and IT labor could be saved if an SD-WAN solution could provide Business Continuity without requiring an additional network connection?
  • Does the SD-WAN solution automatically shape traffic to guarantee QoS regardless of fluctuating network conditions?


  • Does the SD-WAN solution being considered provide sufficient security for business communications? Are interoffice communications protected with encryption?
