Aiming to help businesses increasing the communication network to run seamlessly and stably and move towards the economic recovery after the Covid-19 pandemic crisis, CAT Telecom Public Company Limited (CAT) strengthens its leadership of modern technology and innovation to meet the need of all business fields by offering SD-WAN technology to help the business grow firmly and steadily. Recently the Manager of Data Communication Product   Department, Nisachol Kaewruang shared CAT’s aspiration in her talk entitled “How SD-WAN will make your business successful” at a seminar Vertical Business 2020 where guests from various business fields including healthcare, finance as well as retail business joined the seminar. The seminar was held during July 21-23, 2020 at Carlton Hotel Bangkok Sukhumvit.

Miss Nisachol said that the business with multiple branches now requires a faster and more stable information connection to enhance business growth and the increasing demand for more complex data connectivity so CAT has developed and expanded its services for businesses with multiple branches with one of the most emerging trends in communication networks technology SD-WAN (Software Defined Wide Area Network).   

"Back in the late '90s, businesses connected their networks to differentiate branches with a private network called Leased Line and Frame Relay technology. Until the 2000s, they brought the MPLS /IPVPN technology which is also a private network type to use in the business for faster and more securely connected. Nowadays, we are in the era of the technological transition where the trend has gradually changed, each business has a  public network to access the Internet, which consumes more and more bandwidth and also needs the stability at the same time, resulting in the wan systems being more redundant to manage than before in working system tracking, network loss tracking, network quality monitoring, link load balancing management, and network security policymaking, the sharing between the private and public network and network data analysis. This makes it more complicated to connect businesses with multiple branches until the arrival of SD-WAN technology which helps to manage the complexity of network connectivity faster and more conveniently." 

There are many advantages of SD-WAN which can meet all types of businesses such as the Zero Touch Provisioning technology. This feature allows the devices to be provisioned and configured from the central office automatically. Moreover, ZTP can be installed easily and quickly as SD-WAN automatically retrieves settings from the cloud and enables branch offices to be flexibly connected to the head office and reduces the workload of limited staff in branch offices.

Besides, the entire network can be managed from a centralized management at the headquarter as well as monitoring the use of the network in each branch, setting website or application access meanwhile maintaining its security in a high level. For example, the automotive business or the car industry wants to send a confidential image of the design of the new car so they can set the system to send it via the MPLS network or some organizations do not allow employees to use some applications, all can be configured and set by the main network at the center.

SD-WAN is also a Multi-WAN network that can connect with various kinds of connection types such as Multiprotocol Label Switching (MPLS), Internet Broadband and 3G/4G LTE which can be used together in active/active mode. That’s enabling the use of real-time applications such as video conferences or VoIP (Voice over IP) reaching its highest quality and efficiency and that can meet the need of hospital business that tends to provide service through video conference phone services for patients. For example, patients who have chronic diseases are in need to see a doctor regularly or patients who have the appointments to get their medication at a hospital continuously, using this technology can help lessen the burdens of both patients and doctors in travelling and also prevent the risk of the infection of the COVID-19 pandemic situation eventually.

 Besides, SD-WAN can reduce the cost of network management in each branch office that enables organizations to plan the management in using WAN in each branch more appropriate, stable in use, and also meets the need of the security as well.
