SD-WAN

 

SD-WAN offers enterprises high degree of flexibility for WAN load balancing, optimization and visibility. SD-WAN consolidates multiple networking functions into a single software-defined vCPE platform which virtualizes all the network functions with enhanced service agility, security and QoS (Quality of Service).

 

 

Organizations with distributed branch offices are having difficulty installing and maintaining WAN implementations. Current WAN technologies are complicated, expensive, and rigid. For example, when provisioning a network service to a branch office, organizations require a new CE (Customer Edge) to be sent to the branch office, plus new lines, configuration, and synchronization with PEs (Provider Edge), and of course, the presence of a technician. The expenses end up being relatively high.

Software-Defined WAN technology is currently driving Wide Area Networks' expansion, providing substantial benefits to organizations requiring increased bandwidth for their extended networks. Using low-cost internet bandwidth provides secure and flexibly configured network access to ensure network resource demand is reliably satisfied.

When you think of a filmmaker's arsenal of equipment, it probably conjures up images of video cameras, boom mics, lighting kit, etc. That isn't a wrong assumption by any stretch. However, there is more to it than that given how filmmaking and technology have evolved. Today, in an era of live streaming and high-definition content, reliable connectivity is just as important as traditional considerations such as cinematography. This is where mobile SD-WAN appliances come in. Mobile SD-WAN appliances are now an essential piece of equipment film crews and creators must have on hand, especially when filming in locations with spotty internet connectivity.     

In order to maintain high customer responsiveness, increase sales, and reduce wide area network costs and complexities, large-scale retailers are turning to software-defined wide-area networking (SD-WAN) systems. SD- WANs run on virtualized servers that deliver high availability and agile branch office connectivity. Intel® Network Builders partner Lanner Inc. recently worked with SD-WAN expert 128 Technology to deliver SD-WAN for 5,000 stores of a nationwide auto parts retailer.

The growing trends of cloud computing, Big Data, mobile applications and globalized enterprises have contributed to the rising demands of real-time applications, with successful examples such as Work From Home, remote desktop, video conferencing, telemedicine and third-party payments. However, latency and interruptions between networking nodes are currently the primary challenges, as network traffics continue to grow exponentially from B2B/B2C e-commerce and other real-time applications. To meet the demands for QoS (quality of service), SD-WAN has emerged as a performance-boosting and cost-effective solution.

For the past couple years, SD-WAN has been the remedy to networking challenges in various fields, such as medical, emergency rescue, retain and so forth, making it one of the fastest-growing technologies in decades. Indeed, the ease of deployments, simplified maintenance and application-prioritized performance have helped businesses improve productivity and reduce overhead. In fact, even construction industries can benefit from SD-WAN.

Since the outbreak of COVID-19 pandemic, many municipal and national governments have imposed lockdown policies, forcing their people to stay home. Companies with branches worldwide have already instructed their employees to work from home for a certain period of time. However, the cure of the pandemic is still under experiment without a definite release date, the challenges regarding working from in terms of connectivity, bandwidth and security to ensure business continuity will remain.
