What is SD-WAN?
Cisco Meraki Software-defined WAN is a new approach to network connectivity that lowers operational costs and improves resource usage for multi-site deployments, allowing network administrators to use bandwidth more efficiently and ensure the highest possible level of performance for critical applications without sacrificing security or data privacy.
Traffic distribution over multiple pathways ( Internet, cellular, MPLS) with built-in load balancing and automatic failover capabilities

Policy-based routing: Traffic path assigned based on source, destination, or application
Dynamic path selection:Traffic path is chosen per-application based on loss, latency and jitter
Intuitive, scalable VPN solution to connect remote sites with ease ( Auto VPN )
AES Encryption to ensure data privacy
Intelligent path control
Easy-to-configure IPsec overlay using Meraki Auto VPN
Why Deploy SD-WAN?
Today, IT departments are under pressure to do more with less: manage more sites and more clients with limited budgets and a relatively small team, all without any reduction in reliability and security. The high cost of enterprise WAN connectivity, support, and personnel combined with the growth of bandwidth-hungry streaming applications and cloud-based services, is forcing many network admins to search for alternative solutions.
With SD-WAN, remote sites are connected over low-cost Internet links secured by VPN. MPLS-like reliability is provided through multiple uplinks with load balancing capabilities, intelligent path control, and automatic failover.
DUAL-ACTIVE VPN UPLINKS
In addition to supporting dual WAN uplinks and automatic failover, the MX also has the ability to build multiple VPN tunnels that are active simultaneously on both uplinks, whether they are Internet or MPLS connections. Traffic can then be load-balanced across these tunnels to make optimal use of available bandwidth.
POLICY-BASED ROUTING (PBR )
PbR functionality allows administrators to assign traffic to a particular VPN path based on criteria such as traffic protocol, source, destination, or application.
DYNAMIC PATH SELECTION
Dynamic path selection allows administrators to set performance thresholds for different types of traffic, in order to ensure that critical applications and data transfers always use the best path based on the loss, latency, and jitter over the available VPN tunnels.
