What is the advantage of SD - WAN?

　　As data analysis, the media flow, storage requirements and the increase of data backup, the data center, cloud, branches and other remote location of data transferred between more and more. Traffic growth makes WAN (WAN) and its running on the performance of the application must be optimized.

　　Traffic has risen steadily, the network administrator can see sensitive data transmission delays are on the increase. Offer scalability and throughput in flow transmission of WAN and application performance optimization solutions, has become the inevitable choice of the enterprise.

　　Advantages of WAN

　　Using data deduplication, compression and other protocol optimization technology to optimize performance, including higher bandwidth capacity, network latency, protocols, and overall network traffic monitoring and management.

　　At the same time, the software defined WAN (SD - WAN) technology is becoming a new method of network, can provide a variety of performance and cost advantages, including end-to-end network visibility and feedback, in order to improve transmission efficiency. The technology also created from proprietary hardware devices to SD - the path of the WAN, the WAN is agile programmable, enables the enterprise to keep up with the pace of the innovation of IT.

　　SD - WAN can provide advantages associated with software definition network (SDN), but in a wide area network, the network deployment and management, through automation SDN and SD - WAN virtualization resources, to improve performance, service delivery and improve availability, at the same time reduce the total cost of ownership.

　　SD - WAN by measuring the basic network traffic index, such as delay, packet loss, jitter and availability to run. Through these data, SD - WAN can active response to real-time network conditions, choose the best path for each packet. In many cases, the SD - WAN adopters can take advantage of the manufacturers of proprietary function of the solution. For example, Riverbed SteelHead RiOS can accelerate the SSL on the WAN traffic.

　　SD - WAN often integrated into the enterprise existing WAN, the SD - WAN an advantage of the overlay is can support MPLS and mixed WAN, no matter what type of network infrastructure can provide improvement.

　　SD - WAN adoption is growing fast, because the technology provides a wide range of operational and financial advantages, including:

　　SD - WAN routers can combine multiple WAN the bandwidth of the connection. The enterprises use the SD - WAN can according to need to add or subtract a WAN connection, also can combine cellular and fixed circuit connection. On the premise of SD - WAN, according to the change of demand, can be flexible to increase or decrease the bandwidth, SD - WAN technology can also make the WAN service rapid deployment to a remote site, without the need for IT to deploy.

　　The Internet links are usually much cheaper than a carrier-grade MPLS connection, carrier-grade MPLS connection is usually affected by the supply time and expensive price. SD - WAN technology makes enterprise effectively use all of the available network connections to meet all their requirements, and don't have to worry about maintenance free backup link.

　　Available in the SD - WAN, WAN traffic transmission in the process of the traffic is encrypted, and through the study of the fragmentation of network to improve network security, once the attack can minimize losses. SD - WAN can also help IT administrators continuous monitoring of the amount and type of traffic on the network, to quickly detect attacks.

　　MPLS link tends to provide high reliability of packet transmission, and Internet uplink will often fail. In order to make up for this problem, many used the SD - WAN enterprises to choose from different providers order multiple Internet links, so that in the case of a link failure guarantee 99.99% availability.

　　The application of SD - WAN technology enables the Internet to create a secure connection, high-performance, eliminates the MPLS network caused by return. The SD - WAN to cost effective way to provide business applications, at the same time optimization software as a service (SaaS) and other cloud-based services. The technology also by implementing automation to improve the efficiency of branch of IT, and provide reliable and low cost for the Internet of things project link.

　　Using distributed architecture and is using Internet technology of enterprises should be in ease of use and manageability, and existing MPLS network integration ability and intelligent automatic adjustment traffic evaluation SD - WAN solution.
