The top key SD-WAN advantages are: Centralized control over network traffic. Providing end-to-end connectivity to all enterprise applications. A flexible, configurable and easy to use network that supports a wide range of data-intensive applications. Providing end-to-end connectivity to corporate intranet and web servers. The ability to manage security risks, help reduce costs, improve service quality and increase scalability.
In order to fully appreciate all the key SD-WAN benefits, it is necessary to understand what SD-WAN really is. SD-WAN is an extensible WAN platform which supports both client and server mode traffic to multiple destination IP addresses with full WAN authenticity. This provides companies with a cost effective method for providing fast and low latency access to their data through a local area network (LAN). A WAN is also a great choice for supporting critical applications and services that require real-time application processing on the same network.
Today, there are a number of WAN vendors that offer various WAN solutions based on a variety of technologies such as ISCOns, L2TP/IPsec, ATM and ICMP. However, one of the most popular and highly used WAN solution is MPLS which stands for Multiple Protocol Label Switching Service. MPLS is used in conjunction with Wide Area Networking (WAN), which is a kind of network that allows different local area networks (LANs) to connect to each other. MPLS is one of the main reasons why a lot of enterprises are moving towards having a properly configured and networked office environment. MPLS gives companies the ability to reduce their costs related to centralizing network tasks such as controlling the speed of the internet, setting up internet access control panels, monitoring website traffic, controlling the content of e-mails sent out etc. This enables enterprises to achieve a high level of productivity.
