The traditional WAN (Wide Area Network) technology has long been the main option for IT, audio, and data network infrastructure. Along with the development of technology, now comes SD (Software-Defined) -WAN. Both the Traditional WAN and SD-WAN have their respective advantages. However, for various reasons, a number of companies or organizations tend to use SD-WAN.
Approximately, what advantages does SD-WAN have compared to Traditional WAN? SD-WAN is a unique approach to wide area networks because it combines traditional WAN technologies, such as MPLS (Multiprotocol Label Switching) and internet connection.
This allows a company or organization to direct traffic to a remote location and multiple offices or branches. For more details, here are some advantages of SD-WAN over Traditional WAN: Multiple link resilience Traditional WAN environments usually have one network link going to each location. With SD-WAN, various types of WANs can be combined, both private and public networks, and from different ISPs. So that this can be an advantage of SD-WAN because it can eliminate a single point of failure that can bring down the network.
Supports cloud storage applications (cloud) Traditional WANs are based on conventional routers that are not cloud friendly. A company or organization implementing a Traditional WAN needs to reshuffle all traffic – including those going to the cloud – from branch offices to a data center hub or headquarters where advanced security checking services can be implemented.
With SD-WAN, new lines can be added quickly and easily to sites requiring more capacity. By linking sites directly to the internet, SD-WAN reduces the likelihood of bottlenecks and delays common to longer WANs. Ease of implementation When a company or organization opens a new branch office, business processes, operations, and others can become more complex. The cost factor can swell. SD-WAN allows a company or organization to quickly set up a reliable and secure network, using whichever ISP is most suitable for each location.
Maximizing performance and productivity The lag caused by limited bandwidth capacity impairs application performance resulting in poor user experience and lost productivity. Unlike the traditional WAN architecture, the advantages of the SD-WAN can be seen from the model designed to fully support applications hosted in data center, public, or private cloud locations and Software as a Service (SaaS) solutions.
SD-WAN allows a company or organization to easily assign key applications to multiple links, including internal lines and Internet connections, providing a different quality of service assurance (QoS) for each. This enables the company to apply the right resources in every situation to maximize performance and productivity while minimizing costs.
