As business environment changes, cloud computing technology matures, and the growth of remote work force increases, it is very important for enterprises to establish stable and secure connection between headquarters, branches, and data centers. Traditionally, WANs have been based on physical connections and dedicated bandwidth utilizing SLA-backed private multiprotocol label switching (MPLS) or leased line links to an organizations’ main data centers for all application and security needs.  But that comes at a premium price for connectivity and operational complexity and limited visibility associated with multiple point products. This network architecture usually results significant management overhead and difficulties, especially when trying to troubleshoot and resolve issues. Traditional WAN or MPLS connectivity cannot meet the radical change in network demands caused by digital transformation and an increasingly widespread remote workforce, but SD-WAN can. 

VTX SD-WAN (Software-Defined Wide Area Network) service uses SDN (Software-Defined Network) technology to simplify WAN deployment and management by separating network hardware from its control plane. The technology resides at the network edge and is managed via edge appliances. VTX SD-WAN virtually bonds the transport links between sites, and not caring the type of data circuit or wireless connection is used at each site. It “virtually” chooses the best path available to route traffic. At the same time, VTX SD-WAN combines WAN optimization and application-based intelligent technologies such as routing, private secure tunneling, end-to-end QoS, and global backbone network to provide secure high-speed, stable, and reliable WANs for enterprises, while significantly reducing deployment, operation and maintenance costs, and to achieve operational continuity and efficiency.
