WAN Wrap-Up

In recent years, organizations across a number of industries have begun to realize the benefits that a software defined WAN can bring. SD-WAN technology can enable enterprise users to better take advantage of a range of online capabilities in a more efficient way, spurring increased adoption of these solutions.

SD use expands beyond the data center
IT Business Edge contributor Carl Weinschenk recently reported that while the deployment of software defined technologies had traditionally taken place in data center environments, it is now more often being leveraged in enterprise WANs.

Software defined solutions are now being used outside the data center, enabling enterprises to reap the benefits as well. Software defined solutions are now being used outside the data center, enabling enterprises to reap the benefits as well.

“During the past year or so. the term software defined wide area network (SD-WAN) has become popular,” Weinschenk wrote. “As the name implies the idea is to export the advantages from the data center to the wide area network.”

In this way, enterprises are able to reap all the advantages of SD technology alongside data center operators. The use of multiprotocol label switching, IP virtual private networks, DSL and cable broadband offers optimal redundancy, security and quality of service not seen before in enterprise networks. This provides an overall enhanced end user experience for enterprise staff members, helping them to become more productive members of the workforce.

“The software defined network concept is a win/win,” Weinschenk stated. “Networks become more flexible and both capex and opex shrink because less expensive, generic hardware is used. Changing the mission of a network element or data path no longer involves changing out equipment.”

“Users are not only noticing overall improved services, but specific advantages depending on the application.”

SD-WANs benefit critical applications
As enterprises bring SD technology into their infrastructures, users are noticing overall improved services. Specific advantages depending on the application being supported and utilized are realized from it as well. Network World contributor Larry Hettick noted that SD-WAN can be a boon for on-premises voice and UC solutions. Industry expert Daniel Teichman told Hettick that real-time UC systems have “specific requirements for packet loss, latency and jitter to ensure a quality experience.”

“Successful service delivery requires knowledge of the network being used in order to meet those requirements, otherwise it is possible, even likely to run into user dissatisfaction,” Teichman said. “[A] better option is to have bandwidth allocation and packet prioritization be done using a software-defined WAN. In essence, the continuously-available data center architecture is now accompanied by a high-performance, highly reliable WAN to keep business up and running around the clock.”

With an SD-WAN solution in place, specifically¬†Talari’s THINKING WAN, the network becomes smart, and is able to make real-time decisions about the treatment of each data packet with full awareness of the quality of each link. The technology allows the best possible path to be selected for critical traffic – such as that associated with UC and voice systems – to ensure that issues like latency and jitter don’t impact the end-user experience.
