Traditional WAN (Wide Area Network) edge routing is giving way to Software-Defined Wide Area Network (SD-WAN) with integrated Software-Defined Access (SD-Access). According to industry projections, the worldwide SD-WAN market will be worth $26 billion by 2028. This transformation is inevitable as consumers and businesses want a streamlined and dependable network for maximum efficiency.
WAN Edge Routing?
A WAN is a widely shared private network that connects several local area networks together. To do this successfully, edge routers are used on the existing network.
A WAN edge router is an internal or external device that is located at the periphery of a network that facilitates the interconnections between the network and external networks. It can be used to link multiple remote networks using the External Border Gateway Protocol over the internet. WAN edge routing aids the transfer of data between networks. It could be on-premises or software-enabled. The traditional way of WAN edge routing used hardware devices, separate from WAN optimization and security appliances edge products. The emergence of complex applications made it necessary to find solutions to traditional WAN edge routing limitations. This is fulfilled in SD-WAN and a virtualized access protocol solution, SD-Access.
What is SD-WAN?
Why SD-WAN is the future of WAN edge routing.
Traditional edge routing backhaul architecture of sending traffic to data centers before transmission results in latency and impairs the seamless flow of the network. SD-WAN’s ability to recognize applications provides for intelligent routing on the cloud. SD-WAN can adapt to transport impairment in the network and give the best quality of experience (QoEx).
SD-WAN is cost-effective in terms of signal efficiency and enables a simple and secure flow of traffic to the cloud. SD-WAN may link users and applications by utilizing transport services such as LTE, MPLS, and the internet. Because SD-WAN does not rely on pre-existing links, it may also update routing lists and TCP/IP addresses. Furthermore, SD-WAN may be tailored to an enterprise’s specific requirements. Tailored for business provides a centralized setup that can be swiftly deployed throughout the network with improved visibility and decreased chance of data packet loss. With the addition of a secure access service edge, the company can now execute security checks directly in the cloud.
What is SD-Access?
How SD-Access is revolutionizing WAN edge routing.
Using a single network fabric, SD-Access simplifies the network and ensures operational effectiveness and optimal user experience. It improves existing access management processes through automation, network segmentation, access policies and endpoint monitoring via a single network fabric. With the help of automation, operations processes such as continuous endpoint monitoring and mobile device management can be carried out seamlessly. It constantly checks for vulnerabilities and contains potential risks when discovered without much interruption to business which makes it secure.
Automation also aids a seamless network. Network end-to-end segmentation helps to separate user, device, and application access without affecting changes to the network and serves as a layer of protection and security where one endpoint is compromised. This also reduces the cost of threats and attacks and the time spent in managing access. Security compliance is also heightened by its ability to monitor access IP addresses, access control lists and VLANs.
The data acquired from automation can also drive insights to improve operations. It makes it easy for IT to set network access and centrally configure and manage user policy, throughout the network. It is easy to increase the scope of a traditional network by integrating outdoor IoT points into the IT workflow.
SD-WAN and SD-Access as the future of WAN edge routing.
