IT decision-makers are continually seeking new ways to keep their company’s applications and systems online, up-to-date and secure. Yet as applications become more complex, workloads become more intense, and customers become more demanding, IT pros need to identify and deploy versatile networks better suited to meet their growing demands.
IntroductionBut what exactly are IT decision-makers looking for from their networking solutions? A recent Spiceworks survey of more than 250 IT decision- makers from across the U.S. provides deep, and sometimes surprising insights into how these IT pros view Ethernet, MPLS and SD-WAN networking technologies, including the challenges, benefits and drivers of utilizing these services.
In each of the three surveys conducted (Ethernet, MPLS and SD-WAN), reliability, security and quality of service all ranked above cost/value when it came to critical factors in evaluating networking solution providers.
Introduction 3
What IT Pros Think of EthernetBusinesses appreciate Ethernet because it provides the higher bandwidth and capacity organizations need to manage data growth and application performance, while enhancing the security of every connected location.
A large majority of survey respondents said they currently deploy Ethernet for either Carrier (60%) or Metro (46%) solutions. (Carrier Ethernet is for Internet and for communication among business, academic and government local area networks (LANs). Metro Ethernet is for use in metropolitan area networks (MANs).)
A smaller group said they deploy Ethernet for National (30%) or Multipoint-to-Multipoint (34%) support.
Nearly two-thirds of organizations have current maximum bandwidth levels of 100 GbE (32%) or 40 GbE (31%), while others report having less capacity.
Still, most organizations do not feel bandwidth constrained. More than 3 out of 4 respondents believe that their current Ethernet solution either exceeds (22%) or adequately supports (55%) their current business needs.
It’s important to note that respondents anticipate the need for increased bandwidth to support future needs, with more than 4 in 5 (81%) reporting that they will require more bandwidth within the next 3 years, including 27% that believe they will require significantly more bandwidth.

Top SD-WAN Benefits Goals of Deploying SD-WAN
The Spiceworks survey revealed important data about how IT decision-makers view Ethernet, MPLS and SD-WAN networking solutions, including what drives consideration and purchase, what challenges have been experienced, and what benefits and positive business outcomes have been realized.
Still, there are some significant insights to be called out about each of the technologies, as well as data points that are similar across Ethernet, MPLS, and SD-WAN solution, and those that are disparate.
Noteworthy data on the individual technologies include:
• IT pros currently use Ethernet solutions to support business-critical solutions, including email, databases, and VoIP, but in the future see Ethernet as a vital solution in areas like cloud and hosted services, big-data and analytics, and development and testing.
• Respondents highly value MPLS solutions to protect their enterprise through private, dedicated connectivity and enhanced security.
• More than half of current SD-WAN users see it as critical to organizational functionality, including more than 7 in 10 respondents who consider it vital for their T1/T3 service, cloud services and MPLS.
ConclusionNoteworthy data that spans across all three technologies include:
• While most organizations do not currently feel they are bandwidth constrained, more than 4 in 5 report that they will require more bandwidth in the next 3 years.
• Cost was considered a challenge in deploying Ethernet, MPLS, and SD-WAN; it never ranks as the top challenge of any of the technologies.
• More than half of the respondents in the MPLS and SD-WAN surveys expressed the preference of purchasing networking solutions as part of a bundled offering, as opposed to a single solution. In the Ethernet survey the number that preferred bundles was 46%.
• More than 70% of organizations using Ethernet and MPLS, and more than 60% using SD-WAN, are considering or evaluating solution vendors to assist with technology solutions.
