I. INFORMATION

Hi-Tech SD-WAN is a service developed by Pho Tue SoftWare Solutions JSC to help organizations and businesses build a virtual WAN with performance equivalent to a traditional WAN connection by replacing part or all of the MPLS connection with other connections such as Internet, 4G, LTE..., while providing additional advanced features to ensure the safety and security of the organization and business.

Hi-Tech SD-WAN provides customers with a solution to establish a high-performance WAN based on many types of transmission channels (MPLS, FTTH, 4G, LTE...). With a diverse deployment model, Hi-Tech SD-WAN helps customers achieve stability when connecting services between different branches and is especially suitable for organizations and businesses with many applications on the current cloud computing platform.

1. Application Optimization
   Hi-Tech SD-WAN improves application performance and service quality for remote workers or branch offices. Optimizes application delivery by using caching, storing recently accessed information in memory to speed up future access.
2. Cost Optimization
   Viettel SD-WAN helps customers reduce costs and increase transmission capacity through the use of mobile connections and low-cost lines.
3. High Customizability
   By continuously monitoring applications and WAN resources, Hi-Tech SD-WAN is flexible and can quickly adjust to changing network conditions to maintain efficiency, prioritizing customers' important applications over other types of data. SDWAN will virtualize transmission services commonly used in wide area networks such as MPLS, broadband Internet services and 4G/5G/LTE. SDWAN then views these services as network resources (resource pool). SDWAN allows to utilize broadband connections in the resource pool to transmit application traffic.
4. Ensure continuous connection
   Hi-Tech SD-WAN has a mechanism to ensure network continuity to avoid affecting customers' business, maintain connections with the best quality, minimize network connection loss time, automatically switch to alternative network connections to ensure customer service quality.

II. FEATURES

1. Virtual WAN Setup
   Software-controlled virtual WAN setup connects business branches regardless of the type of transmission channel.
2. High Availability
   Minimize network outage time, automatically switch to alternative network connections to ensure customer service.
3. Quality of Service
   Prioritize bandwidth for the most important applications.
4. Security
   Compared to MPLS, SD-WAN leverages security tools (IPSEC) to authenticate, monitor, and encrypt the connection channel.

III. ADVANTAGE

1. Centralized Management
   Helps businesses optimize resources for network system management personnel.
2. Centralized monitoring
   Helps customers be more proactive in operating their network systems.
3. Increase stability and readiness
   Customers can build a backup system from the transmission line to the device, maximize bandwidth as well as optimize in prioritizing packet transmission on the best quality line.
4. Cost savings
   By replacing MPLS lines with other lines such as Internet, 4G, LTE... customers can save on investment costs, system operating costs while still ensuring network quality for applications to operate normally, almost equivalent to MPLS lines.
