What is SD-WAN?
Within the new technologies, specifically SD–WAN is having a great impact on all companies as it brings with it an evolution in the communications WAN communications that has not occurred for years.
What is SD-WAN?
It is the software-defined WAN. It is a new approach to network connectivity that reduces operational costs and improves resource utilization for multi-site deployments.
It allows network administrators to use bandwidth more efficiently and ensure the highest level of performance for critical applications without sacrificing security or data privacy.
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 fine-grained control over 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 outages of highly performance-sensitive traffic such as VoIP.
So, what does SD-WAN offer?
In answer to this question, it allows administrators to maximize network flexibility and bandwidth efficiency. Operational costs and time spent on bandwidth management are reduced. Simplify WAN management.
How does it do it?
In this publication we are going to focus on Meraki SD-WAN.
The Meraki SD-WAN implementation is composed of several key features, built on AutoVPN technology. It connects remote delegations securely, without tedious manual VPN configuration. 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 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 we have already mentioned in the past, IT departments have limited budgets, have to do more with less, manage multiple sites, clients, devices, applications, deal with the high cost of enterprise WAN connectivity with dedicated access?
With SD-WAN, remote delegations are connected through low-cost Internet access, for example by local ADSL, but secured by VPN. MPLS-like reliability is provided through multiple uplinks with the capabilities of:
– Traffic distribution and load balancing, intelligent path control (chosen per application based on loss, latency and instability) 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
Dual active 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 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 jitter over available VPN tunnels.
Summary:
Operating costs and time spent on bandwidth management are reduced.
- Independent transport. Allows the establishment of independent transports that reduce costs and increase bandwidth.
- Application Optimization. Delivers an optimal user experience for SaaS applications and extends seamlessly into the public cloud.
- Network control.
Provides end-to-end segmentation to protect business-critical computing resources. - Secure connectivity.
- Makes it possible to meet SLAs in business-critical applications.
