SASE model developed by Gartner ties into SD-WAN, edge computing and SD-Branch, so it warrants attention from networking teams.

Developments in factors as varied as cloud services, security, containers and white-box switches can make a positive impact for SDDNCs in the coming year.

The internet of things has such a wide range of use cases and individual devices that network architects have to pay attention to a wide combination of variables for communication, power, bandwidth, reliability, cost and more.

Many of the topics and discussions at the recent Open Networking User Group (ONUG) conference emphasized one very important shift in the networking industry: leading IT organizations are moving to a DevOps organizational structure and eliminating the traditional silos of server, storage and networking in favor of cloud centric, cross-functional teams. Moreover, these changes in IT organizational structure are having a significant impact on networking requirements (e.g. adaptability and programmability) and fueling the adoption of open network software.

Software defined networking (SDN) offers significant opportunities and challenges for enterprise IT professionals. SDN has the potential to make networks more flexible, reduce the time to provision the network, improve quality of service, reduce operational costs and make networks more secure.

In order to be successful in the fast paced Internet world, leading carriers must quickly introduce new services and reduce costs. Network Functions Virtualization (NFV) is a new technology enabling communications service providers (CSPs) to transform their networks. The goal of NFV is to help providers realize the innovation and cost curves enjoyed by the IT community.

Software defined networking (SDN) offers significant opportunities and challenges for enterprise IT professionals. SDN has the potential to make networks more flexible, reduce the time to provision the network, improve quality of service, reduce operational costs, and make networks more secure.

Will there be a market for SDN network operating systems? The answer will be critical to the evolution of SDN standards and the development of applications that leverage SDN capabilities.

SDN is a game changer for adoption of commercial off-the-shelf (COTS) technology in the network industry.

Security is one of the leading challenges for IT professionals. And securing the data center (and related applications) in the era of public, hybrid and private clouds presents a complex set of problems for IT. The rise of SDN technologies will change the dynamics around securing the data center network, offering opportunities for improved automation and as well as new security concerns.

There has been a lot of hype concerning software defined networks (SDN) and OpenFlow. What does SDN mean for you, and how should enterprises prepare for the coming changes in network architectures?
