What is SD-WAN?<\/h3>\n\n\n\n
SD-WAN is a company-owned WAN solution that is optimized using Software Defined Networking (SDN). Company traffic is routed efficiently and securely through the internet. Monitoring and management are handled as cloud applications and no longer physically from the end device on site. Flexible and agile network management is abstracted from a preconfigured virtual overlay. In short: SD-WAN means virtualization of the network.<\/strong><\/p>\n\n\n\n
Which companies benefit most from SD-WAN?<\/h3>\n\n\n\nIn principle, SD-WAN suits any company that operates several locations and attaches great importance to continuous, uninterrupted processes, whether outsourced or operated in-house. However, it is clear that larger companies with many locations, regardless of location size, are particularly suitable for the SD-WAN solution<\/a>.<\/p>\n\n\n\n
Is SD-WAN available even with poor local connectivity?<\/h3>\n\n\n\n
A resounding yes! SD-WAN enables the implementation of site connections via the broadband internet and LTE network. The dynamic SD-WAN feature called multipath optimization automatically selects the appropriate transmission path depending on load, in order to eliminate performance deficits in advance.<\/p>\n\n\n\n
Why SD-WAN over classic MPLS?<\/h3>\n\n\n\n
$\"Technical$ <\/figure>\n\n\n\n
Digitization, cloud applications (Amazon AWS, Microsoft Office 365, Salesforce) and virtualization often result in large bandwidth requirements. Most WAN constructs consist of a mixture of expensive MPLS connections and Internet connections that are encrypted via IPsec. Large MPLS bandwidths are often expensive, and the price jump is enormous, especially abroad. Since MPLS is mainly managed by the carrier, administering these structures is inflexible and cost-intensive. Experience shows that IT spends a lot of working time maintaining ongoing operations. A hybrid solution combining SD-WAN and MPLS is possible too, and companies weighing a migration from MPLS to SD-WAN<\/a> can plan the switch step by step.<\/p>\n\n\n\n

How SAVECALL supports your SD-WAN selection<\/h3>\n\n\n\n
<\/div>\n\n\n\n
The relatively young SD-WAN market is littered with many manufacturers with very different focuses. Without in-depth market knowledge, orientation is difficult, as the portfolio of providers varies greatly. This is exactly where SAVECALL is the right partner: we advise vendor-neutrally on whether a SD-WAN solution via a managed service provider<\/a> or in-house operation fits your company better, and work with you to develop a tailored solution.<\/p>\n\n\n\n
<\/div>\n\n\n\n
Conclusion<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\n
SD-WAN makes company networks more flexible, cheaper and easier to manage, especially for companies with multiple locations. Whether as a complement to or replacement for MPLS: a non-binding SD-WAN trial at the location of your choice quickly shows whether the switch is worthwhile for your company.<\/p>\n\n\n\n

Frequently asked questions about SD-WAN<\/h3>\n\n\n\n
What is SD-WAN?<\/strong>
SD-WAN stands for Software Defined Wide Area Network, a company-owned WAN solution optimized through Software Defined Networking. Traffic is routed efficiently and securely through the internet, while monitoring and management run as a cloud application instead of physically on site. A preconfigured virtual overlay abstracts the network management. In short: SD-WAN virtualizes the corporate network.<\/p> <\/div>
Which companies benefit most from SD-WAN?<\/strong>
SD-WAN suits any company with multiple locations that values continuous, uninterrupted processes, whether outsourced or operated in-house. Larger companies with many locations, regardless of size, benefit particularly. Companies looking to move from expensive MPLS lines to more affordable internet connections also gain significantly from SD-WAN.<\/p> <\/div>
Is SD-WAN available even with poor local connectivity?<\/strong>
Yes, SD-WAN enables site connections via broadband internet and LTE networks. Dynamic multipath optimization automatically selects the appropriate transmission path depending on load, eliminating performance deficits in advance. This makes SD-WAN usable even for locations with limited local infrastructure, as long as basic internet connectivity is available.<\/p> <\/div>
What are the advantages of SD-WAN over MPLS?<\/strong>
SD-WAN significantly lowers costs since it runs on cheaper internet lines instead of expensive MPLS connections. Centralized real-time management, high automation and simple provisioning of new locations at the touch of a button also save IT resources. Flexibility in choosing providers and contract terms remains, while hybrid models with MPLS are still possible.<\/p> <\/div>
Should SD-WAN be operated as a managed service?<\/strong>
For ongoing operations, a managed service provider handling design, rollout and monitoring is generally recommended. The SD-WAN market is young and highly fragmented, so solid market knowledge is needed to compare providers fairly. A good managed service provider acts as a technology partner rather than just a service vendor.<\/p> <\/div>
How does SAVECALL support your SD-WAN selection?<\/strong>
SAVECALL advises vendor-neutrally and finds the right SD-WAN solution for your site connectivity, individually tailored to your infrastructure. Together we clarify whether a managed service provider or in-house operation fits better, and support planning, selection and testing. A non-binding SD-WAN trial at the location of your choice is available at any time.<\/p> <\/div> <\/div>\n\n\n
