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).

 

 

Software-defined WAN solutions can bring unparalleled agility and cost savings to networking, which has been the primary fuel for the rapid growth of SD-WAN in recent years.  Organizations, from enterprises, small-medium businesses to cloud and managed services providers, can deliver more responsive, more predictable applications at lower costs in less time than the traditionally used legacy equipment.

Organizations are increasingly embracing cloud computing to support new applications, keeping pace with ever-increasing quantities of data, and fluctuating customer demands.  Software Defined Wide Area Networks (SD-WANs), as a hardware appliance, was a necessary first step as it supported the transition from legacy systems, and could handle the workloads and complexities of multi-cloud distribution.

The Covid-19 pandemic has created a ‘new normal’ of work-from-anywhere, making the transformation of both WAN and security architectures a top priority for the enterprise.

The disparity between workplace and in-home security is also brought to the fore, highlighting the inadequacy of any one-size-fits-all approach to security. With differing roles, devices and security policies in homes and businesses, an Edge Appliance must be able to automatically detect individual users and devices on the network and apply an appropriate security policy for each.

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.
