Software Defined Wide Area Network (SD-WAN) service refers to how SD-WAN is delivered to users currently using software. SD-WAN services pioneers the virtual layering network and allows enterprises to leave any combination of transport service like broadband and mobile networks to be used alongside standard multi-protocol label switching (MPLS) to deliver more flexible, availability and redundancy.
SD-WAN services replace the normal fixed type network with virtual software that uses intelligent routing to transfer data packets through the most secure and better lines possible. SD-WAN as a service offers several key benefits which include:
Global Reach: SD-WANs services commonly have points of presence (PoP) globally distributed which reduces latency or packet loss and increases bandwidth for highly distributed workforces and cloud assets connecting to the nearest PoP.
Simplified management: Managed SD-WAN is designed to be responsible for most of the management tasks, providing technology for the service providers. Users only need to link the network to their environment.
Reduced Cost: since SD-WAN is an advanced version of traditional WAN and has been designed to do most of the work, it will save cost on the acquisition of operators for the network. It also makes a cheaper alternative to replace the expensive MPLS links.
Distinguishing Feature of SD-WAN service
Authentication: With SD-WAN services, only approved users can have access to the network. Only authentic devices and users are allowed to connect to the network and send traffic to one another. Users are not verified with passwords alone but with multiple authentication processes.
Network Segmentation: segmentation is the division of a network into zones based on certain factors which helps to reduce network traffic among the parts. It reduces cybersecurity by limiting how far a threat can spread and also limit the movement of an intruder from one zone to another. In essence, we can say network segmentation can stop harmful threats from reaching zones that cannot defend themselves against attacks.
Flexibility and scalability: SD-WAN services are very flexible, always moving with the dynamic nature of network requirements and businesses. Through scalability remote users can alter configuration and add services as required, thereby, adding to the dynamic needs. It can easily adapt new networks into new branches and systems in order to aid connectivity and multiple network systems. In essence, SD-WAN services serve as a network that can host a variety of managed services.
