The Netify glossary for SD-WAN terms and questions.
For many businesses, allocating network resources and prioritising specific applications is still a static setup. Utilising traditional Wide Area Network (WAN) solutions, the prioritisation of applications is defined by network administrators and then…
Microsoft Azure Software Defined Wide Area Networks (SD-WAN) offers a network management solution for connecting Azure regions. Azure SD-WAN connects distributed workforces and networked appliances regardless of whether they are on-premises, remote, at…
Large businesses are typically spread over multiple branches and so branch office connectivity is essential for operating a distributed enterprise. With traditional WAN networks, businesses found managing and optimising branch office connectivity…
SD WAN is a good option to replace a basic internet VPN service. In many ways, SD WAN is an evolution of the standard IPSec VPN service, which is still used today to meet specific or simple requirements. IPSec remains a popular encryption security option…
A cloud-based Software Defined Wide Area Network (SD-WAN) solution is a network overlay that enables businesses to leverage standard cloud capabilities such as instantly available scaling and a more powerful feature set. By abstracting the network…
As the utilisation of cloud services within organisations is increasing, traditional enterprise network architectures have struggled to adapt to the changing requirements that using the cloud introduces. Software Defined Wide Area Network (SD-WAN)…
SD WAN technology can support MPLS as one of several types of connectivity. It is designed to be connectivity agnostic, meaning that service providers can offer support for MPLS, as well as internet service provider connectivity across 4G, 5G, and…
SD WAN (Software Defined Wide Area Networking) is better than MPLS (Multi Protocol Label Switching) because the technology is more in-line with the needs of almost all modern Enterprise businesses. * Note that there is always an exception to the rule and…
Businesses are typically transitioning from their traditional network solutions to Software-Defined Wide Area Network (SD-WAN) solutions due to performance-based incentives. One of the most compelling capabilities of SD-WAN is link aggregation, which…
Network Latency refers to the round-trip time delay for data transmission between a source and destination within a network. This means that latency is measured from the point of initiation (e.g. a download link is clicked) to the point in which the…
SD-WAN orchestration is a tool that provides Software Defined Wide Area Networks with a centralised management. This central management system provides SD-WAN solutions with a single interface with the capability for automation, coordination of network…
Over the Top (OTT) Software-Defined Wide Area Network (SD-WAN) is a solution for creating a virtual overlay on top of existing network infrastructure independent of the underlying transport links. This means that OTT SD-WAN can leverage pre-existing,…
Quality of Service (QoS) is a set of techniques to manage traffic across a network in order to optimise preferential performance. These optimisations vary between solutions but may prioritise specific network traffic, critical applications or services,…
Software-Defined Wide Area Network (SD-WAN) solutions offer businesses with the capability to utilise path selection through dynamic traffic routing in order to increase network performance and reliability. SD-WAN leverages multi-path utilisation,…
Software-Defined Perimeter (SDP) is a security framework designed to dynamically create individual connections between the network perimeter and each user/device. Developed by Cloud Security Alliance (CSA) in 2013, SDP addresses the limitations of…
Traffic steering is an essential feature that Software-Defined Wide Area Network (SD-WAN) solutions implement to improve the performance and reliability of your business network. Traffic steering intelligently routes data across multiple paths, improving…
SD WAN elements can be deployed in a physical WAN edge, virtualized server instance, or software application. The main reasons for deploying SD WAN using a physical appliance are as follows: Physical dedicated hardware appliances offer better throughput…
A single individual or company did not invent SD WAN - the term 'Software Defined Wide Area Network' was referenced by Gartner in 2014. Before SD WAN, the term SDN (Software Defined Networking) was initially discussed in 2007 as a technology to separate…
MPLS will remain a component of hybrid WAN architecture, but SD WAN is and will be and is the primary choice for most organizations. In the minds of most IT decision-makers, SD WAN has now firmly replaced MPLS to meet the needs of almost all Enterprise…
One of the greatest challenges for global enterprises has been the setup and deployment of new network edges that are dispersed across a wide range of geographical locations, whilst minimising costs of deployment. Traditionally, this would have required…
