What is SD-WAN?Maria Cruz Alcocer
Within the new technologies, in particular SD-WAN is causing a great impact in all companies as it leads to an evolution in WAN communications that did not happen for years.
What is SD-WAN?
It is the WAN defined by software. It is a new approach to network connectivity that reduces operational costs and improves the use of resources for multisede deployments. It allows network administrators to use bandwidth more efficiently and ensure the highest level of performance for critical applications without sacrificing data security or privacy.
Software-defined WAN (SD-WAN) is a set of functions designed to allow the network to dynamically adjust to changing WAN conditions without the need for manual intervention by the network administrator. By providing detailed 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 avoid highly sensitive performance-aware traffic interruptions, such as VoIP.
Therefore, what does SD-WAN offer?
In response to this question comment that allows administrators to maximize the flexibility of the network and the efficiency of bandwidth. Operating costs are reduced and the time allocated to the administration of bandwidth. Simplify WAN management
As it does?
In this publication we are going to focus on Meraki SD-WAN. The implementation of Meraki SD-WAN consists of several key features, built on AutoVPN technology. Connect remote delegations securely, without the tedious manual configuration of VPN. Leveraging the power of the cloud, Meraki MX Security Appliances configures, monitors and maintains your VPN so you do not have to. Intuitive and scalable VPN solution for connecting remote sites with AutoVPN ease. For more information on AutoVPN technology: https://meraki.cisco.com/technologies/auto-vpn
Why choose SD-WAN?
As in previous occasions we have already commented, IT departments have limited budgets, they have to do more with less, manage multiple sites, clients, devices, applications, deal with the high cost of corporate WAN connectivity with dedicated access …
With SD-WAN the remote delegations are connected through low-cost internet access, for example by local ADSL, but guaranteed by VPN. The reliability similar to MPLS is provided through multiple uplinks with capabilities of:
- Traffic distribution and load balancing, intelligent route control (chosen by application based on loss, latency and instability) and automatic failover.
- Visibility and control of centralized network, QoS and bandwidth management.
- Policy-based routing: assigned traffic path based on the source, destination or application.
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 balanced in the load 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 route selection allows administrators to set performance thresholds for different types of traffic, to ensure that critical applications and data transfers always use the best route based on loss, latency, and instability over them. VPN tunnels available.
- Operating costs are reduced and the time allocated to the administration of bandwidth.
- Independent transportation It allows to establish independent transports that allow to reduce the costs and increase the bandwidth.
- Application optimization It offers an optimal user experience for SaaS applications and extends infallibly in the public cloud.
- Control of the network. It provides end-to-end segmentation to protect computing resources vital for businesses.
- Secure connectivity
- It makes it possible to meet SLAs in critical business applications.
