SD-WAN aims to support multiple connection types and VPNs between sites, offer dynamic and flexible WAN connectivity, reduce costs, improve network performance and provide a simple management interface.
A typical SD-WAN deployment consists of hardware or virtual devices installed at each of the client’s sites (edge) and networked with other devices located at the headquarters, data centers or recovery sites, or in the Cloud.
Software-Defined Wide Area Networking (SD-WAN) is a revolutionary way to approach the simplification of branch office networking and assure optimal application performance by using centrally controlled and managed WAN virtualization.
Unlike traditional WANs, SD-WAN delivers increased network agility and cost reduction. Software-Defined WAN has its roots in Software-Defined Networking (SDN), the underlying principle of which is to abstract the network hardware and transport characteristics from the applications that use the network.
Boost network data rates, reliability, and flexibility while slashing connectivity costs with Multi-WAN Link Load Balancing technology. SD-WAN load balancing engine can distribute the traffic of up to numbers of Internet links and can route data using smart intelligent algorithms. It all adds up to high speeds and rock-solid dependability at a savings of up to 90% compared to solutions built on traditional WAN and other expensive links.
With the WANOps, all your cable, DSL, cellular, and other links will work together to handle even the most demanding traffic, without lags or downtime. When you need more speed, add more connections. Internet Load Balancers are application aware, so you can ensure that most important data and applications always get VIP treatment. The best link for a given task is identified, and the traffic is directed accordingly, optimizing the available bandwidth and creating a smarter network.
Active-Active Deployment: should an ISP link become unavailable, one or more links will handle the traffic until the troubled link returns to normal.
Outbound traffic balancing: the link balancer will be able to distribute traffic leaving the organization across available links based on organizational preferences
Inbound traffic balancing: through smartDNS, a link balancer will be able to distribute incoming traffic across all selected links. Common examples include roaming VPN clients, webmail access, transactional applications and email retrieval by remote users.
Bond multiple slow WAN links to aggregate bandwidth at sites with poor connectivity options. Failover to cellular when other links go down. Use quality of service to control bandwidth usage and centrally manage wireless access points with built-in wireless LAN management. Bond WAN links and failover between multiple DSL/cable links to improve bandwidth availability and increase productivity. Stay up and running round-the-clock with automatic failover to cellular. Aggregate bandwidth and failover between multiple WAN links.
