What is SD-WAN?
What is SD-WAN?
It is the software-defined WAN. It's a new approach to network connectivity that reduces operational costs and improves resource usage for multi-site deployments. It enables network administrators to use bandwidth more efficiently and ensure the highest level of performance for critical applications without sacrificing data privacy or security. Software Defined WAN (SD-WAN) is a set of features designed to allow the network to dynamically adjust to changing WAN conditions without the need for manual intervention by the network administrator. By providing granular control of how different types of traffic respond to changes in WAN availability and performance, SD-WAN can ensure optimal performance for critical applications and help prevent outages from highly performance-sensitive traffic such as VoIP.So what does SD-WAN offer?
In response to this question, comment that it allows administrators to maximize network flexibility and bandwidth efficiency. Operating costs and time spent on bandwidth management are reduced. Simplify WAN management.As it does?
In this post we are going to focus on Meraki SD-WAN. The Meraki SD-WAN implementation is made up of several key features, built on AutoVPN technology . Connect remote branches securely, without tedious manual VPN setup. Leveraging the power of the cloud, Meraki MX Security Appliances configures, monitors, and maintains your VPN so you don't have to. Intuitive and scalable VPN solution to easily connect remote sites to AutoVPN. For more information on AutoVPN technology : https://meraki.cisco.com/technologies/auto-vpnWhy choose SD-WAN?
As we have already mentioned on previous occasions, IT departments have limited budgets, they have to do more with less, manage multiple sites, clients, devices, applications, deal with the high cost of business WAN connectivity with dedicated access ... With SD-WAN, remote branches are connected through low-cost internet accesses, for example by local ADSL, but guaranteed by VPN. MPLS-like reliability is provided through multiple uplinks with capabilities to: - Traffic distribution and load balancing, intelligent path control (chosen by application based on loss, latency, and jitter), and automatic failover. - Centralized network visibility and control, QoS and bandwidth management. - Policy-based routing: traffic route assigned based on source, destination, or application.SD-WAN functions
Active Double VPN uplinks: In addition to supporting dual WAN uplinks and automatic VPN 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 be load balanced through these tunnels to make optimal use of the available bandwidth. Policy-based routing (PbR): The PbR functionality allows administrators to assign traffic to a particular VPN route based on criteria such as traffic protocol, source, destination, or application. Dynamic route selection: Dynamic path selection allows administrators to set throughput thresholds for different types of traffic to ensure that critical applications and data transfers always use the best path based on loss, latency, and jitter over traffic. VPN tunnels available. Summary: Operating costs and time spent on bandwidth management are reduced.- Independent transportation. It allows to establish independent transports that allow reducing costs and increasing bandwidth.
- Application optimization. It offers an optimal user experience for SaaS applications and is infallibly spread across the public cloud.
- Network control. Provides end-to-end segmentation to protect critical business computing resources.
- Secure connectivity.
- Makes it possible to meet SLAs in critical business applications.
