"Software-defined networking ( #SDN ) is having a profound impact on businesses," starts out a new report based on a survey of IT pros involved with the disruptive technology approach.
One of these impacts is on the usage of traditional virtualization techniques such as virtual local-area networks (VLANs), according to the new report, "SDN Growth Takes IT Infrastructure by Storm," from QuinStreet Enterprise (available for free upon supplying registration information).
Noting that VLANs have been around for more than 30 years, the report said that 43 percent of survey respondents already are using VLANs, a much higher percentage than that reported for newer SDN and network functions virtualization (NFV) technologies. However, the outlook going forward shows more growth for SDN than VLANs, said QuinStreet, which compared the two technologies.
