FREMONT, CA – There was a time when organizations employed network models hosted by a central data center linked to fixed devices within the network. However, the workforce of today requires mobile, robust solutions with easy accessibility. As a result, organizations have incorporated cloud networks to host collaboration applications. The integration of cloud-based networks has enabled the information technology (IT) teams to enhance connectivity, and the DevOps teams to deliver augmented applications.
The cloud network, though robust and flexible, offers several obstacles to the traditional wide area network (WAN). The applications and services in the cloud are not hosted in a physical space in the workplace. The network communications are interconnected and sophisticated, and the bandwidth requirements often range beyond the capability of the organizations. Since the WAN infrastructure is widely distributed, it is difficult to maintain transparency in the network. Also, the sophisticated nature of the system often hinders the resolution of failures.
Replacing the traditional WAN network with SD-WAN infrastructure offers a cloud-enabled
The network which utilizes comprehensive software-based technology to deliver hyperconnected and robust connectivity within the organizations. The cloud-enabled WAN can quickly adapt according to the evolution of the network infrastructure and user requirements.
The SD-WAN not only offers basic WAN connectivity, but also possesses the capability of delivering premium services, including WAN optimization, meshed VPN, voice and video conferencing, and application delivery control (ADC) to ensure consistent access to applications. It also provides QoC maintenance for bandwidth consuming applications and offloads functions.
The SD-WAN controller is one of the most significant features of the infrastructure. The centralized controller technology enables the organizations to prioritize traffic, set policies, and deliver physical and virtual device management for the connected devices in the network. It can also be leveraged to manage QoS performance metrics for different network tunnels, maintain identification, connectivity, and performance of applications, and identify the operational state of the network tunnels between distinct WANs.
The reasons to adopt SD-WAN include enhanced agility, cost-effectiveness, and many other features not available in the traditional WAN. Since the WAN is virtualized, it provides flexibility to the transfer of data. The organizations can leverage MPLS for facilitating a dedicated line for access to a central VoIP solution.
